June 2007 Installing the Hardware 5
Note. Alcatel-Lucent provides factory-installed blank 
cover plates for empty backup power supply or 10 Giga-
bit expansion module bays. Do not remove these cover 
plates unless a backup power supply or expansion module 
is to be installed immediately at the corresponding bay.
5 If you are installing multiple switches in a stacked 
configuration, repeat steps 1 through 4 for the remaining 
switches that will make up the stack.
6 Once all OmniSwitch 6800 Series switches have been 
removed from their packaging, continue to “Setting Up 
the Switch.”
Setting Up the Switch
Note. Due to their airflow and access requirements, 
OmniSwitch 6800 Series switches cannot be wall-
mounted.
Airflow Considerations
Be sure that your switch is placed in a well-ventilated, static-
free environment. Always allow adequate clearance at the 
front, rear, and sides of the switch.
The following diagram shows recommended minimum clear-
ances for adequate chassis airflow and access to components at 
the rear of the chassis:
