  • Page 39: Network Configuration

    NETWORK CONFIGURATION The SNMP/Web adapter network interface is very flexible and can be configured for operation in various environments. This section details all possible network configuration combinations, while it is recommended to refer to Console/Web interface sections for the specific configuration commands / menus.

  • Page 40: Dns Configuration

    DNS CONFIGURATION DNS configuration affects the SNMP/Web adapter ability to resolve symbolic hostnames to IP addresses, and may impact other functionality (such as e-mail sending, for example): The SNMP/Web adapters can be configured to automatically obtain DNS server address (e.g. Primary and Secondary DNS server as specified in the DHCP response).

  • Page 41: Multi-server Network Shutdown (rccmd)

    6 MULTI-SERVER NETWORK SHUTDOWN (RCCMD) The SNMP/Web adapters include a module for Multi-Server Network Shutdown. This module allows the configuration of a shutdown strategy for several servers powered by the UPS when the batteries are running low following a prolonged mains failure. NETWORK SHUTDOWN WITH RCCMD RCCMD (Remote Console Command) is a mechanism that allows the execution of commands on remote systems.

  • Page 42: Network Configuration

    Finally, it is possible to configure the actual condition that triggers the RCCMD Shutdown command: • After X minutes that the UPS is running on battery • At X minutes of estimated minutes remaining of battery autonomy • When the UPS signals a low battery condition Note that a low battery condition will force the shutdown of the configured RCCMD Clients regardless of the chosen shutdown condition.

  • Page 43: Rccmd Client Relay

    RCCMD CLIENT RELAY The maximum number of RCCMD Clients that can be managed by the SNMP/Web adapter is limited. In order to reach a higher number of RCCMD Clients, one or more of these clients can be configured to operate as relays. Basically, the RCCMD Client needs to be configured so that it will execute a batch or script file that issues more RCCMD Shutdown commands.

  • Page 44: Security

    The adapters come with a predefined supervisor user, whose default username and password are ge and ge. New users can then be created using either the console or the web interface. NOTE Only the supervisor user can create new users.

    SERVICES (ACCESS METHODS) The table below lists the available services (access methods), highlighting the major security features for each interface.

  • Page 46

    The fingerprint may be checked against the information provided by the SNMP/Web adapter to confirm to SSH server identity. On the console interface inject the ssh-fingerprint command. Below is a sample output of the ssh-fingerprint command: GEDE> ssh-fingerprint 1024 6e:07:31:58:16:91:ae:2e:43:6f:03:64:94:57:55:6d ssh_host_rsa_key.pub 1024 06:97:69:97:cd:93:1b:b6:29:ca:34:e5:8c:35:7c:6e ssh_host_dsa_key.pub 1024 d1:9b:50:13:b3:e3:98:8e:8c:76:49:14:be:21:ed:b3 ssh_host_key.pub The output can be interpreted as follows:...

  • Page 47: Ssl Certificates

    7.3.2 SSL Certificates HTTPS is not a protocol itself, but it actually refers to HTTP communication over SSL (Secure Sockets Layer) connection. HTTPS uses public-key cryptography to protect the communication. With HTTPS, the server sends back its identification in the form of a digital certificate. The certificate usually contains the server name, the trusted certificate authority (CA), and the server's public encryption key.

  • Page 48

    On the console interface inject the ssl-fingerprint command. Below is a sample output of the ssl- fingerprint command: GEDE> ssl-fingerprint MD5 Fingerprint=8F:A1:CE:8B:B3:04:E7:07:90:6D:02:77:6F:EE:9E:22 SHA1 Fingerprint=F5:D2:CA:27:BF:DA:98:31:39:6F:18:8C:C5:9C:BC:6C:D3:62:15:AC It can be seen that the thumbprint shown by the web browser (with thumbprint algorithm shown as sha1) matches the SHA1 fingerprint as shown by the ssl-fingerprint command.

  • Page 49: Customer Responsibility

    Particularly, it is recommended to focus on the following settings: • The default username and password for the superuser are ge and ge. It is recommended to change default username and password (by configuring new and unique ones) at the initial card configuration •...

  • Page 50: Other Functionalities

    OTHER FUNCTIONALITIES SYSTEM TIME The SNMP/Web adapter provides means to maintain the system time. Particularly, the adapter will maintain an internal clock when powered-up, while an RTC with battery back-up will hold date/time information when off (or during power-cycles). This system offers a sufficient accuracy in the short term. However, in the longer term the time drift may become significant.

  • Page 51: Ups Load Alert

    8.3.1 UPS Load Alert The SNMP/Web adapter monitors the UPS Output Percent Load and reports a UpsLoadAlert when the load drops of a defined percentage (the actual load step detected is also saved in the UPS log). This functionality warns the user that there has been a drop in the UPS load. This could indicate potential issues with the UPS load (fuse blown, breaker tripped, unit off, etc.).

  • Page 52: Maintenance

    Therefore: • Never power off or un-plug the device during upgrade • Use only GE officially released software • Avoid unnecessary upgrades (in line of practice, only perform upgrades when recommended to do so by GE) CONFIGURATION FILE The SNMP/Web adapter settings are stored in non-volatile memory.

  • Page 53: Troubleshooting

    10 TROUBLESHOOTING 10.1 TROUBLESHOOTING UPS CONNECTION The SNMP/Web adapter front panel features a LED marked ‘UPS’. This LED should be OFF in normal conditions. If the LED is ON then there is a problem in the communication with the UPS. NOTE: It may take up to one minute for the adapter to synchronise the communication with the UPS.

    10.6 TROUBLESHOOTING E-MAIL NOTIFICATION (SMTP) When e-mail notification via SMTP is configured and enabled, the SNMP/Web adapter will notify the selected recipients upon UPS alarm activation / deactivation. If problems are experienced with this functionality, follow the flowchart below to identify the root-cause of the problem and implement proper corrective actions.

  • Page 57: Troubleshooting Network Shutdown

    10.7 TROUBLESHOOTING NETWORK SHUTDOWN When experiencing difficulties with the Network Shutdown functionality (RCCMD), there are a few diagnostic tools that can be used. The first step is to ensure that the SNMP/Web adapter can reach the RCCMD Client. The actual network connectivity between the two nodes can be checked with the usual ping command.
