CMM Slot Locations
In a non-redundant (i.e., single CMM) configuration, the CMM module can be installed in either Slot A or
Slot B of the chassis. In redundant CMM configurations, a CMM is installed at both Slot A and Slot B
(refer to
for more information on CMM redundancy).
Note that both Slots A and B are longer than the Network Interface (NI) slots. These slots run vertically
and are located near the center of the chassis. Refer to the figure below.

OS7700-CMM Versus OS7800-CMM
OS7700-CMM and OS7800-CMM modules offer identical functions. In addition, OS7700-CMM and
OS7800-CMM front panels provide the same port configurations and status LEDs. However, there are two
notable differences:
1
The physical dimensions of the OS7700-CMM differ from those of the OS7800-CMM. As a result,
OS7700-CMMs and OS7800-CMMs are not interchangeable between the 7700 and 7800 chassis types.
2
OS7700-CMMs and OS7800-CMMs use identical processor boards. However, OS7800-CMMs use
twice the number of network interface-related ASICs on the fabric board. This is because OmniSwitch
7800 switches support up to 16 network interface (NI) modules and OmniSwitch 7700 switches support up
to 8 NI modules.
