Fan Tray Assembly

Caution The DC PEM and DC PDU assembly weighs 14.0 pounds (6.35 kg.). Use two hands when handling the power supply.

Warning Power to your router must be Off and all cables disconnected before you connect the DC PDU. The DC PDU is not a hot-swappable, field replaceable unit.

Fan Tray Assembly

The Cisco 12404 router has one fan tray (Figure A-8). Facing the rear of the chassis the fan tray assembly is located on the right side of the chassis. The fan tray assembly maintains acceptable operating temperatures for the internal components by drawing cooling air through the card cages from side to side.

The fan tray assembly is a sheet metal enclosure containing seven fans and two fan controller cards.
