Follow these steps to install fan trays in the chassis.
Procedure
Step 1
Lift the fan tray (with two hands) and slide it halfway into the module bay.
Step 2
Slowly push the fan tray into the chassis until it mates with the backplane connector at the back of the chassis
bay.
To prevent damage to the connectors, do not use excessive force when inserting the fan tray into
the chassis.
Caution
Step 3
Tighten the captive screw(s) on the fan tray using the 6-inch long number 2 Phillips screwdriver to a torque
of 10 in-lb to secure it to the chassis.
Step 4
Repeat Step1 through Step 3 for the second fan tray.
On the Cisco ASR 9922 Router, the third and fourth fan trays (under the middle cage) are installed
upside down compared to the first and second fan trays (above the middle cage).
Note
Installing Cards in the Chassis
This section describes how to reinstall the RSP cards, RP cards, FCs, and LCs back into the chassis.
See the
Cisco ASR 9000 Series Aggregation Services Router SIP and SPA Hardware Installation Guide
for
information about installing shared port adapter (SPA) and SPA interface processor (SIP) cards.
Be sure to verify that you are inserting a card into its correct slot. RSP/RP cards must only be inserted in the
two slots reserved for RSP/RP cards (RSP0, RSP1, RP0, RP1). FCs must only be inserted in the FC slots of
the Cisco ASR 9922 Router and Cisco ASR 9912 Router. All other slots are for LCs.
Caution
Unoccupied card slots must have a blank filler card installed for electromagnetic compatibility (EMC) and to
ensure proper air flow through the chassis.
Caution
Be careful to avoid damaging the electromagnetic interference (EMI) gasket that runs along the full height of
the card front panel edges. Damage to the EMI gasket can affect the ability of your system to meet EMC
requirements.
Caution
Handle all cards by the metal card carrier edges only; avoid touching the board or any connector pins. After
removing a card, carefully place it in an antistatic bag or similar environment to protect it from ESD and dust
in the optic ports (fiber-optic line cards).
