If a fan fails, the fault indicator on the fan canister will glow. For more information about
indicators, see "Checking the Controller Enclosure Indicator Lights" on page 36.
If you replace the fan canister and continue to experience problems, the controller
enclosure may have defective components or connections. Check the storage
management software (TPSSM7) for indications of other component failures.
The fan/communications canister is a single, removable unit containing two cooling
fans. This canister plugs into a slot at the center at the rear of the controller enclosure, just
above the power supplies (Figure 2-10). The fan/communications canister has three
captive screws and a pull ring for securing and removing the canister. The canister
contains dual fans that provide a redundant cooling system to both power supply
canisters. If one fan within the canister fails, the other will continue to operate. A single
fan will provide sufficient air circulation to prevent the power supplies from overheating
until you can replace the entire fan/communications canister.
