Omni Switch/Router Chassis and Power Supplies

OmniS/R-5
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
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.
