Take protectionmeasures such as wearing an earmuff or earplug. In addition, make goodpreparation before the hot-swapping to minimize the operation time.Before you install or replace a switching fabric module on an operating12904E switch, first remove the fan tray. Install the fan tray immediately afteryou finishing installing or replacing the switching fabric module.For good ventilation, install filler panels in empty switching fabric module slots.Long-time exposure to strong air flow might cause discomfort.

It applies to the12904E switch. The 12904E switch has two fan tray slots: FAN1 and FAN2.One fan tray is sufficient for heat dissipation of the switch.

Whenthe fan tray is operating, ambient air flows in through the air vents in the MPUand LPU/interface module adapter panels, circulates through the switchingfabric module section, and flows out through the air vents in the fan tray withthe heat carried from the MPU, LPU, and switching fabric module sections.Captive screwHandleSwitchingfabricmodulestatusLEDFanPanel side view Fan side viewFan traystatusLEDPositioning pinESD-preventivewrist strapPhillipsscrewdriverBefore you install a fan tray, install switching fabric modules or filler panels inthe switching fabric module slots.To install a fan tray in the FAN1 slot, orient the fan tray so that the LEDs are onthe left side of the front panel.
