WS-X4593-E Cisco Catalyst 4503-E Fan Tray, Six Fans, Hot-Swappable

The WS-X4593-E is the fan tray for the Cisco Catalyst 4503-E chassis, and it is the one fan tray model available for that switch. The 4503-E takes a single hot-swappable fan tray.

The tray holds six individual fans. The fans are not field replaceable one by one, and a fan failure means the whole tray comes out. Air is drawn in on the right side of the chassis and exhausted on the left side, which makes the chassis fan tray airflow right to left. The STATUS LED on the tray front panel is green when the tray runs normally and red when one or more fans have failed.

The 4503-E is a chassis with three horizontal slots: the supervisor engine goes in slot 1 and the chassis takes up to two modules, with a 48 Gbps full-duplex backplane per slot. A system with a single power supply needs at least one fan tray and one supervisor engine for the power supply OUTPUT FAIL LED to work properly. The spare number is WS-X4593-E=.

Other Catalyst 4500-E chassis take different trays: WS-X4596-E for the 4506-E and WS-X4597-E for the 4507R-E, including the WS-C4507R-E 7-slot chassis. More chassis parts are in Cisco switches.
