SECTION II - WEBMUX MAIN COMPONENTS
Front View
Switches and Indicator Lights
Power
This switch toggles power on and off. To power off, the switch must be pressed and held for
5 seconds. However, it is recommended that you do not regularly use this power switch to
shut down the unit.
It is highly recommended to use the LCD panel, web interface, or command line
interface to issue a proper system shut down.
Failure / Overheat Indicator
The system monitors the CPU and will flash this indictor light if it should fail. If the system
exceeds the CPU temperature limit, this indicator light will go on and the CPU will add idle
cylces - lowering performance (and heat). This is only likely to occur in cases of CPU fan
failure or a data center cooling failure to the WebMux.
Management LAN Indicator
Under normal operations this indicates activity on the Management LAN interface. Even if
the system is not running, there is still standby power. If there is an active Ethernet
connection in this port and the system is not running, it is useful both as a front panel
indication that there is standby power to the system and that there is a connection link on
the Management LAN interface (indicating that the switch at the remote end of the cable is
up too).
Activity/Reset
This indicator serves two functions, as the disk activity indicator and the HARD RESET
button to force restart the WebMux. Under normal operations the indicator light will
occasionally flicker if during disk activity. It may also indicate that the system may not be
“dead” despite other indicators. When this button is pushed in, it will force a reboot of the
WebMux. Only use this to reboot the WebMux if all other normal means to reboot the unit
(through the LCD, web GUI, or CLI) does not work.
