Sample Extended Double-Wide Network Module
Tip
For information on configuring network module slots to fit extended double-wide network modules, see
the
“Preparing Cisco Router Slots for Network Module Installation” section on page 2-8
.
Note
Extension modules, such as the EVM-HD-8FXS/DID, are equivalent to a single-wide network module.
However, extension modules are not supported in all Cisco access router network module slots. See
Table 1-1
for information on slots supporting extension modules.

Network Module Slot Locations and Numbering on Cisco Access Routers
Most Cisco access router network module slots are numbered from right to left, bottom to top. However,
some routers use different slot numbering schemes. See
Figure 1-5
and
Figure 1-6
for examples of
network module slot numbering on Cisco access routers.
