the password.
The SNMP manager server cannot get information from the IES.
Ping the IES from the SNMP server. If you cannot, check the cable, connections and IP
1
configuration.
Check to see that the community (or trusted host) in the IES matches the SNMP server's
2
community.
Make sure that your computer's IP address matches a configured trusted host IP address (if
3
configured).
I cannot telnet into the IES.
Make sure that a telnet session(s) is not already operating. The IES only accepts one telnet session
1
at a time (or a total of four Telnet and SSH sessions with multiple login enabled).
Make sure that your computer's IP address matches a configured secured client IP address (if
2
configured). The IES immediately disconnects the telnet session if secured host IP addresses are
configured and your computer's IP address does not match one of them.
Make sure that you have not disabled the Telnet service or changed the server port number that the
3
IES uses for Telnet.
Ping the IES from your computer.
4
If you are able to ping the IES but are still unable to telnet, contact your vendor.
5
I cannot use the console port to access the IES.
Make sure you use terminal emulation software with the correct settings. The default settings are
VT100 terminal emulation, 115200 bps, No parity, 8 data bits, 1 stop bit, and no flow control;
although you can use the commands to configure the console port speed.
