Are the Wireless Services Modules (WiSMs) in Catalyst 6500 Switches hot-swappable?
A. Yes, the WiSMs are hot-swappable blades, which means they can be inserted/removed without powering off the switch. The Cisco Catalyst chassis can hold one or more WiSMs, Supervisor Engine 720 modules, redundant power supplies, and cooling resources, in addition to the other integrated services modules. Modules communicate across a fully redundant backplane. This enables hot-swappable capabilities and easy serviceability.
