The OmniS/R-5 chassis has five slots for an 

MPX

 and switching modules (see figure below). 

Slots are numbered from 1 to 5 starting with the topmost slot. Slots for two power supplies 
are located at the bottom of the chassis.

♦ Warning ♦

If you have an OmniS/R-5 with a single power supply, 
do not remove the cover on the empty power supply 
slot. In addition, if you have any empty switching 
module slots in an OmniS/R-5, you must cover them 
with blank panels (available from Alcatel) to prevent 
your chassis from overheating.

Covering empty slots forces air to flow directly over the 
power supplies, thereby cooling them. If the power 
supplies are not properly cooled, they will overheat 
and shut down.

The entire chassis can be wall-mounted or rack-mounted. You can view all cabling, power 
supplies, module interfaces, and 

LED

s at the front of the chassis.

The OmniS/R-5 uses the 

MPX

. Slot 1 is reserved for the 

MPX

; you cannot install a switching 

module in Slot 1. You can install a switching module in Slot 2 (if an 

MPX 

is installed in Slot 1) 

or an 

MPX

. When dual-redundant 

MPXs 

are installed, one of them must be installed in Slot 1 

and the other in Slot 2. Slots 3 through 5 are reserved for switching modules.
