Cooling System
The cooling system in a PTX10008 router consists of two hot-removable and hot-insertable FRU fan trays
(see
Figure 8 on page
32) and two fan tray controllers (see
Figure 9 on page
32).
Two fan tray models and their associated fan tray controllers are available. Both models of fan tray contain
11 fans. The fan trays install vertically on the rear of the chassis and provide front to back chassis cooling.
