The Supervisor Engine IV can be deployed in single-chassis nonredundant mode in the Cisco Catalyst 4006, Catalyst 4503, Catalyst 4506, and
Catalyst 4507R. It also can be deployed in single-chassis redundant mode as an option in the Cisco Catalyst 4507R chassis (slots 1 and 2 only).

SUPERVISOR ENGINE IV REDUNDANCY FOR BUSINESS RESILIENCY
The Cisco Catalyst 4507R chassis using the Supervisor Engine IV has been designed with an optional 1 + 1 redundant supervisor capability for
integrated resiliency. One Supervisor Engine IV is designated as the primary (active) supervisor and is responsible for normal system operation. The
other (secondary) can serve as a standby, monitoring the operation of the primary supervisor.
With the support of stateful switchover (SSO), information is synchronized between supervisors to allow the standby supervisor to immediately take
over in subsecond time when the primary is nonoperational. Layer 2 links are maintained transparently without the need of renegotiating sessions. As
a result, business-critical applications such as voice-over-IP (VoIP) calls are not dropped. Nonstop forwarding (NSF) awareness is also supported,
