FAN TRAYS
Each Cisco Catalyst 4500 Series chassis uses a single fan tray for cooling. All fan trays are composed of independent fans. If one fan fails, the system
will continue to operate without a significant degradation in cooling. The system will detect and notify the user (through LED, command-line
interface [CLI], and SNMP) that a fan has failed and the tray needs to be replaced.
FABRIC-REDUNDANCY MODULES (CISCO CATALYST 4507R AND 4510R ONLY)
The Cisco Catalyst 4500 Series redundancy scheme uses removable fabric-redundancy modules on the passive backplane to switch traffic to the
active supervisor engine. There is one fabric-redundancy module per line card. Fabric-redundancy modules and redundant clocks ship standard with
every Cisco Catalyst 4507R and 4510R chassis. Spare fabric-redundancy modules and clock modules are available for serviceability.
