- XII - Information on Functionality INFORMATION Networking  Depending on the network environment at your premise, cases below may occur.  Unable to obtain a maximum communication speed.  Unable to obtain a stable communication speed.  Unable to establish a communication link.  If your network is connected to an external network, threats of unauthorized intrusion and information leak may increase. Install firewall software on your PCs connected to the Gateway as necessary. Wireless LAN  Standard values of up to 300 Mbps, 54 Mbps, and 11 Mbps present theoretical maximum values of IEEE 802.11 Wireless LAN Standard and do not present actual (effective) data throughput values.  Reachable distance and communication speed of the wireless LAN facility built in the Gateway largely differ with environmental conditions at your premise. These conditions include communication distances, electromagnetic factors (such as obstacles and microwave appliances), performances of connected PCs, and network usage rates.  When an IEEE 802.11b device, an IEEE 802.11g device, and an IEEE 802.11n device coexist in the network at your premise, the throughput of the IEEE 802.11n device may become significantly slow.  To enable communications with an IEEE 802.11n device, wireless encryption on the wireless LAN terminal must be set to “-” (no encryption), “WPA-PSK (AES),” or “WPA2-PSK (AES),” where the last choice is recommended.  WLAN channels 12 and 13 are not allowed to use. Your configuration of wireless channel 12 or 13 is invalid. Firmware upgrade  In order to keep the firmware of the Gateway up to date, the Gateway automatically checks for a new firmware version over an applicable external network and, if a new version is found, upgrades the installed firmware within the predefined timeframe.  During execution of firmware upgrade, all other connections are automatically disconnected.  Execution of firmware upgrade may interrupt your use of services via an external network such as viewing streaming content. If this happens, wait until execution of firmware upgrade is complete and then retry use of the interrupted service.
- XIII - Information on Functionality (Continued) INFORMATION Management of site-specific information  The Gateway can register and store information that is specific to you and your premise. If such site-specific information leaks, your loss may be unpredictable. Take utmost care in managing such site-specific information stored in the Gateway.  You can completely erase the site-specific information by initializing the Gateway. Follow the procedure in Section 8.1, “Initialization of the Gateway.” Important Information on Wireless LAN Security for Privacy INFORMATION  Because wireless LAN uses radio waves instead of LAN cables for communications among devices such as PCs through wireless LAN access points, it has the benefit of LAN connection anywhere as far as radio waves can reach.  Conversely, without proper security settings, wireless LAN may be susceptible to the following threats because radio waves can reach anywhere within their scope beyond obstacles such as walls:  Sniffing: A malicious third party may willfully intercept radio waves, thus stealing the content of communications such as e-mails or personal information such as user IDs, passwords, and credit-card numbers.  Unauthorized intrusion: A malicious third party may intrude on the personal or corporate network without consent, and either steal personal or confidential information (leaking), spread false information while impersonating a particular person (spoofing), overwrite intercepted communications (tampering), or spread malware to corrupt data and crash the system (destroying).  Most wireless LAN adapters and wireless LAN access points are equipped with security measures against the above-mentioned threats. By configuring the settings of such security measures properly, the user can minimize the susceptibility of the user’s wireless LAN system to these threats.  Some wireless LAN adapters and wireless LAN access points may ship with security settings not configured by default. Accordingly, in order to minimize possible threats to the user’s wireless LAN system, the user is required to configure all security settings before the user starts using wireless LAN adapters and wireless LAN access points.  By design, wireless LAN is still susceptible to security breach via special methods. Use wireless LAN with this in mind.  The Manufacturer advises the user to configure, at the user’s own judgement and responsibility, all security settings on wireless LAN devices properly before use, based on the user’s full understanding of possible threats when such settings are not made.  The Manufacturer disclaims any loss due to the user’s failure in configuring proper security settings on wireless LAN devices or due to security breach inevitable by design of wireless LAN.

For proper operation of the Gateway, it is requested that you always keep the firmware version up to date according to the firmware upgrade procedures in this chapter. You can confirm the firmware version currently installed in the Gateway according to the procedure in Section 6.2. There are two firmware upgrade methods: automatic firmware upgrade (see Section 6.3) and manual firmware upgrade (see Section 6.4). INFORMATION  In order to keep the firmware of the Gateway up to date, the Gateway automatically checks for a new firmware version over an applicable external network and, if a new version is found, upgrades the firmware as scheduled. For the purpose of this automatic firmware upgrade, a new version firmware file is downloaded in the Gateway upon finding over the external network or, if the connection is busy, at the time of upgrading the firmware.  During upgrading of the firmware initiated by manual firmware upgrade, the ALARM lamp in the front access area of the Gateway blinks in orange.  While firmware upgrade is in progress, do not disconnect power until installation of a new firmware version is finished. Otherwise, firmware upgrade will not complete successfully.  When the Gateway has downloaded a new version firmware file and is manually restarted before the predefined timeframe by unplugging and plugging the power cord, the Gateway starts up in the new firmware version.  When the Gateway starts up in the state of factory shipment and a new firmware version is found after this startup process, the Gateway automatically upgrades the firmware. Wait until downloading of a new version firmware file, restarting of the Gateway, and upgrading of the firmware are all complete.  For the purpose of upgrading the firmware, the Gateway automatically restarts and all network connections temporarily get disconnected. Accordingly, terminate the ongoing communications, if any (such as communications with the user PC connected to the network), before upgrading of the firmware takes place.  Operation of manual firmware upgrade is not available during upgrading of the firmware, during task scheduling for automatic firmware upgrade, during restarting of the Gateway, or during any setting/maintenance operation.  Firmware upgrade does not guarantee upgrading of all functions to the latest.  Use a firmware version applicable to the Gateway whenever you perform firmware upgrade. Otherwise, the Gateway may become inoperative.  Firmware upgrade may not always keep your settings. It is hence recommended that you back up your settings before upgrading of the firmware takes place.

Is the POWER lamp in the front access area of the Gateway lit in green?  No: Try actions for Stage a.  Yes Is the ALARM lamp in the front access area of the Gateway off?  No: Try actions for Stage b.  Yes When the WAN port in the rear access area of the Gateway is in use, is the WAN lamp in the front access area lit in green or blinking in green?  No: Try actions for Stage c.  Yes When any of the wired LAN ports in the rear access area of the Gateway is in use, is the subject LINK lamp in the rear access area lit in green or blinking in green?  No: Try actions for Stage d.  Yes Is the IP address of the connected PC set to be automatically assigned?  No: Try actions for Stage e.  Yes Is the connected PC able to open and perform the “EMS Gateway” setup page in the browser?  No: Try actions for Stage f.  Yes Is there any other trouble?  Yes: Try actions for Stage g. Stage Symptom Suspected Cause and Action To Be Taken a. The POWER lamp in the front access area of the Gateway is not lit in green.  Check if the power cord plug is firmly inserted in the outlet.  Try connecting any other device to the outlet to see if the power is supplied to the outlet.  If the power cord is plugged to a service outlet of any other device such as PC, plug the power cord directly to a mains outlet. Otherwise, disconnection of power to the service outlet also disconnects power to the Gateway.  Check if the power cord is free of damage. If you find any damage, immediately unplug the power cord from the outlet. b. The ALARM lamp in the front access area of the Gateway is lit in red. The Gateway is in error. Restart the Gateway by unplugging and plugging the power cord with an interval of 10 seconds or longer between unplugging and plugging. c. When the WAN port in the rear access area of the Gateway is in use, the WAN lamp in the front access area is not lit in green or not blinking in green.  Check if both the Gateway and the WAN side equipment are turned on.  Reconnect the LAN cable between the WAN port of the Gateway and the LAN port of the WAN side equipment until you hear a click from each port connection. (Continued on next page)
- 31 - (Continued) Stage Symptom Suspected Cause and Action To Be Taken d. When any of the wired LAN ports in the rear access area of the Gateway is in use, the subject LINK lamp in the rear access area is not lit in green or not blinking in green.  Check if both the Gateway and the destination equipment are turned on.  Check if the wired LAN connection to the destination equipment meets the networking environment of your premise.  Check if the wired LAN facility in the destination equipment (LAN board or LAN card) is properly configured.  Reconnect the LAN cable between the subject LAN port of the Gateway and the LAN port of the destination equipment until you hear a click from each port connection.  When the user prepares a LAN cable, procure a LAN cable of category 5e or higher if 1 Gbps (1000 Mbps) link speed for 1000BASE-T is desired. Otherwise, slowdown of link speed or communication failure may result. e. The IP address of the connected PC is not set to be automatically assigned.  Referring to instruction manual of the connected PC, set up the wired LAN connection of the connected PC so that the IP address of the connected PC is automatically assigned by DHCP server (the Gateway).  To cause the above setting to take effect, the Gateway needs to start up and become ready prior to startup of the connected PC. To ensure this, recycle power of the connected PC while the Gateway is running. f. The connected PC is not able to open the “EMS Gateway” setup page in the browser.  Check if the connection is appropriate referring to Chapter 4 (wired connection) or Chapter 5 (wireless connection).  Set up the OS and the browser so as not to use proxy.  Temporarily terminate firewall and/or antivirus software, if running on the user PC, before trying to open the “EMS Gateway” setup page. The connected PC is not able to perform the “EMS Gateway” setup page properly in the browser.  Enable JavaScript™ in the browser settings.  Use compatible browser defined in Subsection 1.3.2. g. There is any other trouble.  Check if the latest firmware version is applied and, if not, perform firmware upgrade according to Chapter 6.  Initialize the Gateway and set up the Gateway from scratch according to Section 8.1.
- 32 - 7.2 During Use For troubles during use, try actions according to the table below. If the error persists, check if the latest firmware version is applied and, if not, perform firmware upgrade according to Chapter 6. Symptom Suspected Cause and Action To Be Taken Wired LAN connection encounters slowdown of link speed or communication failure. When the user prepares a LAN cable, procure a LAN cable of category 5e or higher if 1 Gbps (1000 Mbps) link speed for 1000BASE-T is desired. Otherwise, slowdown of link speed or communication failure may result. Wireless LAN connection encounters communication failure.  Open the “EMS Gateway” setup page, select Wireless Configuration from Wireless menu, and check if a proper channel of the wireless LAN terminal (user PC) is specified. When the autoselect channel setting fails to establish a wireless connection, change the setting to a specific channel verified on the user PC.  Check if encryption method parameters and Security Encryption Key values match between the Gateway and the user PC. In particular when WEP is in use, ensure that the values of WEP Key Index and WEP Keys #1 to #4 match between the Gateway and the user PC.  When MAC address filtering is in use, ensure that the MAC address of the user PC is registered to the Gateway according to the procedure of Section 5.2.  Wireless LAN connection may fail when the encryption setting of an IEEE 802.11n-based user PC is “WPA-PSK (TKIP)” or “WPA2-PSK (TKIP).” To ensure communications with an IEEE 802.11n-based user PC, change the encryption setting to “WPA-PSK (AES)” or “WPA2-PSK (AES),” where the latter is recommended. As an alternative, if applicable, change the operation mode of the user PC to IEEE 802.11g or IEEE 802.11b. LAN terminals cannot communicate with one another. LAN terminals may not support communications based on domain names. Try not to use domain names. Firmware upgrade fails. Operation of manual firmware upgrade is not available during upgrading of the firmware, during task scheduling for automatic firmware upgrade, during restarting of the Gateway, or during any setting/maintenance operation. The ALARM lamp in the front access area of the Gateway is lit in red. The Gateway is in error. Restart the Gateway by unplugging and plugging the power cord with an interval of 10 seconds or longer between unplugging and plugging.
- 33 - 8. APPENDIX 8.1 Initialization of the Gateway Initialization means deletion of settings made after installation of the Gateway, thereby restoring the Gateway to the state of factory shipment. When the Gateway does not operate properly or when the Gateway is to participate in a completely different network, it is recommended that you initialize the Gateway and set up the Gateway from scratch. Be noted, however, that this initialization completely deletes the settings you made to the Gateway. It is advised that you back up the current settings onto an external medium before you perform initialization. INFORMATION  Log-in authentication settings of user ID and password are important personal information which, if stolen, may be abused. Take utmost care in managing your user ID and password.  Initialization completely deletes the settings you made to the Gateway. It is advised that you back up the current settings onto a hard disk of your PC or similar medium before you perform initialization. To perform initialization, follow the steps below. 1. Unplug the power cord from the outlet to turn off power of the Gateway. 2. While pressing down the INIT button in the rear access area of the Gateway (see Section 1.2 for the button location), plug the power cord into the outlet to turn on power of the Gateway. 3. Keep pressing down the INIT button for 10 seconds or longer. The Gateway starts up in the state of factory shipment.
