Chapter 6. Remote management and system diagnostics
You can use the command-line interface of the EXP2500 environmental service
module (ESM) to perform system diagnostics and other subsystem management
tasks. Before you can issue any commands, you must connect to the EXP2500
ESM Ethernet port, establish a session with the EXP2500 ESM, and then launch its
command-line interface.
Launching the EXP2500 ESM command-line interface
Complete the following steps to launch the EXP2500 ESM command-line interface:
1. Use Telnet, or a terminal application that supports Telnet, to connect to the
EXP2500 ESM Ethernet port that has a default address of 192.168.128.101 and
a subnet mask of 255.255.0.0.
2. Enter USERID as the login name and press ENTER. Leave the password field
blank. The command-line interface launches.
See EXP2500 ESM command-line reference for the list of commands.
