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.

It will take about a minute for the WebMux to completely reboot and begin

reporting activity in the LCD display. This will not reset your settings. It is for forcing

restarts. To perform a factory reset refer to the Factory Reset part in Section IV for LCD

instructions or CLI reference.

LCD and Keypad

Up Arrow Button and Down Arrow Button

These buttons navigate through the menus when the LCD cursor is in the LEFTMOST

position and also allow changing characters in the input fields that you will see to the

right of that position. Note that it is generally best to use the “Checkmark” button for

proceeding through the menus in the LCD display. When the cursor is in the

LEFTMOST position, the “Up arrow” will take you to the previous screen.

These buttons will change letters and numbers (cycling through a list) in the fields where

you enter data. It goes through lower case letters, upper case letters, numbers and

symbols.

Left Arrow Button and Right Arrow Button

These move the cursor left and right, into data entry fields and back. Note that the

“Checkmark” button can be pressed when input is complete, rather than moving back to

the leftmost position, to proceed through the menus.

Rear View

Power Supply

WebMux hot-swappable universal power supplies supports 90-264V input.

 Devices with redundant power supplies should have the power cords plugged in to

separate circuits so WebMux does not fail due to one failed circuit. Properly ground the

WebMux at the grounding terminal.

Ports

IPMI port is for connecting to a management network for access to IPMI services on the

WebMux. This allows you to remotely control power on/off (including soft and hard resets),

monitor temperature, and even access a remote console.

USB port may be used for firmware updates and to collect log data when network options

for those functions are not available. This is a future option that is currently in

development.
