Field Replaceable Units
in the shipping container are complete; notify the project manager or the Customer Care
Center of any discrepancies.
Note: T1100 AS removable media drives and adapter are considered one FRU. Remove
and replace the entire adapter assembly including both removable media drives.
2. Turn OFF the power switch on theT1100 AS chassis.
Next, turn OFF the circuit breakers or power distribution units that supply power to theT1100
AS chassis containing the removable media disk drive assembly to be removed. To locate the
circuit breakers supplying power to theT1100 AS chassis, refer to the system interconnect
diagram for the system type and/or read the labels on the breakers. To access the circuit
breakers on some frames, it may be necessary to remove the plastic covers on the front of the
breakers. If the covers are removed, to maintain NEBS compliance, make sure they are replaced
when the FRU replacement has been completed.
WARNING: AT1100 AS chassis is redundantly powered from both A and B
-48 VDC buses. Ensure that both the circuit breaker supplying A power to a chassis
and the circuit breaker supplying B power to aT1100 AS chassis are turned OFF
by measuring the voltage with a VOM on the cables that connects theT1100 AS
chassis to its breakers. Both A and B power LEDs on the front fascia of theT1100
AS chassis should be OFF.
3. Prepare theT1100 AS chassis for access to the FRU using one of the following procedures:

when working on electronic components.

4. To replace the CD/DVD drives, first open the front fascia by unscrewing the knurled screws
on either side of the chassis, and use the key to unlock the front fascia.
Once unlocked, the front fascia swings open from the top of the chassis. The CD/DVD drives
are above the square fan on the left side of the chassis.

WARNING: This procedure CANNOT be performed while theT1100 AS
chassis is powered on. Never power OFF aT1100 AS chassis until the application
software and platform operating system (OS) are shut down. If possible, use
the procedures in the application manual for a "soft shutdown." If the
application interface is not operating or is not accessible, a hard shutdown
(turning OFF the breakers) is sometimes required. Contact the Customer Care
Center before doing a hard shutdown.
