Expansion Modules
Expansion modules allow Cisco Nexus switches to be configured as cost-effective 10-Gigabit Ethernet
switches and as I/O consolidation platforms with native Fibre Channel connectivity.
The Cisco Nexus 5500 Platform is equipped with expansion modules that you can use to increase the
number of 10-Gigabit Ethernet and FCoE ports or connect to Fibre Channel SANs with 8-, 4-, 2-, or
1-Gbps Fibre Channel switch ports. The chassis supports hot swapping of the expansion modules.
The Cisco Nexus 5548 supports one of the following expansion modules:
• N55 M16P Generic Expansion Module, page 1-20
• N55 M8P8FP Generic Expansion Module, page 1-21
• N55 M16UP Generic Expansion Module, page 1-22
N55 M16P Generic Expansion Module
The N55 M16P Generic Expansion Module (GEM) provides 16 1- or 10-Gigabit Ethernet ports using the
SFP+ transceiver.
Figure 1-18 shows the components that you use to install this expansion module.
