Cisco WS-X4582E Catalyst 4510R-E Fan Tray Module

Cisco WS-X4582-E Catalyst 4510R-E Fan Tray Module is a spare cooling assembly for Cisco's Catalyst 4500 Series switches, designed to fit the Catalyst 4510R-E and the 4510R-E family’s fan bay. The unit houses ten fans (commonly described in catalog listings as a 10-fan tray) and is installed to provide the chassis with redundant airflow for thermal management. Cisco documents identify WS-X4582-E on the fan tray front panel and note that the Catalyst 4510R-E and the 4510R+E use the same fan tray, with the spare variant listed as WS-X4582-E=; end-of-sale notices also acknowledge WS-X4582-E= (and related WS-X4597-E=) as spare fan trays for 4507R-E and 4510R-E, with no direct replacement for this exact module. In service, the fan tray contributes to cooling by distributing airflow across the chassis backplane and line cards, supporting stable performance under load and part of the chassis’s redundancy strategy.
