10 Gbps port LEDs should be lit while the device performs diagnostics. After the
diagnostics are complete, the LEDs will be dark except for those that are attached
by cables to other devices.
If the links on these cables are good and the connected device is powered on, the
link LEDs will light. Table 7 provides more details on specific LED conditions after
system start-up.
Observing the power status LEDs
Table 7 lists the device LEDs that show power status.
The software regularly polls the hardware for power status information. You can
display the status information from any management session using the show
chassis CLI command. In addition, the software automatically generates a Syslog
message and SNMP trap if a status change occurs.
Attaching a PC or terminal
To assign an IP address, you must have access to the Command Line Interface
(CLI). The CLI is a text-based interface that can be accessed through a direct serial
connection to the device or through Telnet connections.
