Replacing an I/O Module for a Cisco Nexus 5548 Switch
To replace an I/O module with another I/O module (Layer 2 I/O module or layer 3 I/O module) you must
remove the right fan module and then pull the I/O module out using the handle of the left fan module,
which is installed in the middle of the I/O module. You then install the replacement I/O module and fill
its fan module slots with the fan modules from the original I/O module.
Note If the module includes the product ID on the front, it is a Layer 3 I/O module (product ID N55-D160L3
or N55-D160L3-V2). The N55-D160L3-V2 uses a newer version of the Layer 3 ASIC and enables higher
table sizes in a future software release from 8K host entries to 16K host entries or from 4K multicast
routes to 8K multicast routes (IPv4). The Layer 2 module (product ID N55-DL2) does not include the
product ID on the front.
