Omni Switch/Router Chassis and Power Supplies
The Omni Switch/Router chassis houses the MPX , switching modules, and one or two power
supplies. The modular design of the chassis provides the ability to configure your Omni
Switch/Router to meet your networking needs. The Omni Switch/Router chassis also offer
such failure resistant features as redundant
MPXs , redundant power supplies, and hot
swapping of switching modules. (See Chapter 3, “Omni Switch/Router Switching Modules,”
for more information on hot swapping switching modules.)
There are three (3) different versions of the Omni Switch/Router chassis. The OmniS/R-3, a
three-slot version, is documented in OmniS/R-3 on page 1-8. The OmniS/R-5, a five-slot
version, is documented in OmniS/R-5 on page 1-10. A nine-slot version called the OmniS/R-9
is documented in OmniS/R-9 and OmniS/R-9P on page 1-13. The OmniS/R-3, OmniS/R-5 and
OmniS/R-9 chassis, the
MPX module, and several switching modules have met FCC Class B
requirements.
♦ Note ♦
In the current release, a maximum of seven (7) 32-port
switching modules (e.g.,
ESX-100C-32W ) is supported in
9-slot Omni Switch/Router chassis.
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-redun-
dant MPXs are installed, one of them must be installed in Slot 1 and the other in Slot 2. On the
OmniS/R-3, Slot 3 is reserved for a switching module. On the OmniS/R-5, Slots 3 through 5
are reserved for switching modules. On the OmniS/R-9, Slots 3 through 9 are reserved for
switching modules.
♦ Important Note ♦
You must have an MPX acting as the management
module; you cannot use any version of the MPM .
Warning
If you have any empty switching module slots in either
an OmniS/R-3 (3-slot) or OmniS/R-5 (5-slot) chassis,
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.
