Booting the Switch
The OmniSwitch 6855 Series switch does not use an on/off 
switch. The power cord is the switch’s only connect/discon-
nect device. The power connector socket is located on the 
switch’s power supply. For more information, refer to the 
OmniSwitch 6855 Series Hardware Users Guide.
To boot the switch, plug the power cord (provided) into the 
power connector socket or power brick at the switch’s rear 
panel. Next, plug the power cord into an easily-accessible 
power source, such as a grounded AC outlet or an Uninterrupt-
ible Power Supply (UPS).
The switch immediately begins the boot process. Allow a few 
moments for the switch to boot completely, then verify the 
status of all LEDs on the switch’s front panel. A successful 
boot displays the following LED states:
If either the OK or PS1 LED states differ from the states 
shown in the table, refer to the OmniSwitch 6855 Series Hard-
ware Users Guide for more information. Contact Alcatel-
Lucent Customer Support if the unexpected LED state persists.
