Installing the Fan Tray
The C-Series chassis contains one field-replaceable fan tray. There are two types
of fan trays that you can install: one contains six fans that run at varying speeds
depending on system temperature; the other contains six fans that run at a
constant speed. For both types of trays, air flows through the system toward the
fans (right to left) and is exhausted on fan-side of the chassis. The fan tray is
accessible from the front of the chassis.
WARNING: To ensure proper temperature and airflow control, the fan tray
must always be installed and operating properly.
NOTE: The system does not have an air filter. Ensure that you clean the
installation site and chassis regularly.
5 Rotate the levers toward the card to seat the backplane connectors and
line card in place. Push on the knurled section of the levers until the
thumb tabs pop up and lock the unit in place.
CAUTION: Installing a card without fully engaging the
locking mechanism might damage the EMI seal on the card
below it when you install that card.
6 Install a blank panel in all slots that do not have a card, and secure it
with the screws provided.
Step Task
1 Slide the fan tray into the fan slot.
2 Gently push on the front of the tray until it stops. The fan tray should be
flush with the chassis.
3 Use a #2 Phillips screwdriver to secure the fan tray into place by
tightening the screws at the top and bottom of the fan tray.
