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 tapped briefly (for less than one second), a
graceful shutdown takes place; in this case file integrity and data is
protected. If the button is pressed and held (for three seconds or longer),
a hard shutdown takes place.
C a u t i o n
A hard shutdown can introduce the risk of hard disk drive (HDD) file
corruption.
If policies on the server that runs on the module have disabled shutdown
without login, you must press the button two or three times. Similarly, if
the server’s power management or screen saver policies have been altered
(which is
not
recommended, as described in the
Installation and Getting
Started Guide ), you must push the button two or three times. In either
case, press the button briefly each time for a graceful shutdown.
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.
The USB device is then available on the headless server.
