You can hot swap the expansion modules during operations, except the Layer 3 GEMs. You must power
down the switch before you can insert or remove the Layer 3 GEMs.

operations.
Layer 3 GEMs (N55-M160L3 and N55-M160L3-V2) provide 160 Gbps of Layer 3 services. The
N55-M160L3-V2 uses a newer version of the Layer 3 ASIC that enables higher table sizes in a future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).
