Troubleshooting the Cooling Subsystem
The Cisco 12404 Internet router has a fan tray assembly located on the left side
of the chassis when you are facing the front of the chassis. The fan tray assembly
assembly provides cooling air for the router components. The fan tray assembly
receives power and signals though a connector mounted on the fan tray, which
mates with a connector mounted on the backplane.
The fan tray assembly contains:
•
7 fans
•
2 controller cards
•
1 connector
Note
In noisy environments listen for the fans. Place your hand at the left side
of the chassis beside the fan tray assembly to feel for air being forced out
the exhaust vents.
