Hardware Components

Front Panel Buttons, LEDs, and

Connectors

This section describes the different buttons, LEDs, and connectors on the

front panel of a module:

■ Module Shutdown button—This button is used to shut down the

module. A message is written to the switch log to indicate the module has

shut down. If the button is pressed briefly (for approximately one second),

a graceful shutdown takes place; in this case file integrity and data is

protected. If the button is pressed and held (for four seconds or longer),

a hard shutdown takes place. (Note, however, that if the domain has

disabled shutdown without login, you must press the button two or three

times.)

Caution A hard shutdown can introduce the risk of hard disk drive (HDD) file

corruption.

■ Note the module can also be shut down by using a CLI command.

Note also that the shutdown button can be enabled and disabled using a

CLI command. See “Device Disable” on page D-4.

■ 10/100/1000T Management Port—This port provides a direct connec-

tion to the SBM for management, typically in troubleshooting situations.

Traffic is not routed through this port beyond the module. Its default IP

address is 192.168.2.10/30.

■ USB Port—This port is used to attach a USB device, such as a flash drive.
