Cisco Systems 4500 manual FAN Trays, Environmental Conditions, Regulatory Standards Compliance

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.

ENVIRONMENTAL CONDITIONS

The Cisco Catalyst 4500 Series requires the following conditions:

∙Operating temperature: 32 to 104ºF (0 to 40ºC)

∙Storage temperature: –40 to 167ºF (–40 to 75ºC)
