Attention:
Possible equipment damage due to overheating – If the shelf is powered on, do not remove both fans at the
same time. Otherwise, the equipment might overheat.
11. Disconnect the left cable chain from its vertical guide rail:
a. Using a flashlight, locate the orange ring on the end of the cable chain attached to the vertical guide rail.
b. To unlatch the cable chain, insert your finger into the orange ring.
c. To unplug the cable chain, pull toward you approximately 1 inch (2.5 cm).
Attention:
Leave the cable chain connector within the vertical guide rail.
Attention:
Possible hardware damage — If the drive tray is powered on, the cable chain is energized until both ends
are unplugged. To avoid shorting out the equipment, do not allow the unplugged cable chain connector to touch the
metal chassis if the other end of the cable chain is still plugged in.
12. Disconnect the left cable chain from the horizontal guide rail, and pull the entire cable chain out of the drive shelf.
If you are performing this procedure with the power on, all LEDs go off when you disconnect the last cable chain connector,
including the amber Attention LED
13. Replace the left fan canister. If the drive shelf is receiving power, confirm that the amber LED on the back of the fan is not
illuminated and that air is coming out the back of the fan.
The LED could remain on for as long as a minute after you reinstall the fan while both fans settle into the correct speed.

2. Unlatch the drive drawer by pulling out on both levers.
3. Using the extended levers, carefully pull the drive drawer out until it stops. Do not completely remove the drive drawer from
the drive shelf.
