9. Insert the new canister into the slot with the handle pointing towards the
center of the slot. Insert the unit in the same orientation as the one that you
removed.
10. Push the canister back into the slot until the handle starts to move.
11. Finish inserting the canister by closing the handle until the locking catch clicks
into place. Make sure that the canister is firmly and correctly seated, otherwise
this can lead to problems.

Replacing a fan module
Remove and replace a fan module.
Replacing a Storwize V7000 Gen2 fan module
Use this procedure to replace a faulty fan module with a new one received from
CRU or FRU stock.
About this task
A fan module is located behind each node canister, and is accessed using the node
canister slot after the node canister is removed.
Do not remove the node canister and faulty fan module before the replacement fan
is on hand. The replacement procedure described must be completed within 5
minutes of the faulty fan module being removed to ensure that components do not
shut down due to excessive temperatures.
When removing a node canister, aim to maximize drive and system availability by
maintaining one online node in the control enclosure. If you cannot maintain at
least one node canister online in the system, then you might need to follow the
system recovery procedure after the node canister is replaced into the enclosure.
Procedure
1. Remove the replacement fan module from its packaging. Familiarize yourself
with the part by reading through this procedure.
2. Remove the node canister that is on the same side of the enclosure as the
faulty fan module. See “Procedure: Removing a Storwize V7000 Gen2 node
canister” on page 279.
3. Locate the two orange locking rings of the fan module inside the left and right
edges of the node canister slot. Note their position relative to the inside of the
canister slot.
4. Simultaneously rotate both rings upwards through 90 degrees, releasing the
fan module from the slot. Pull the locking rings to slide the faulty fan module
out from the canister slot.
5. Ensure that the orange locking rings on the replacement fan module are
rotated open so that they extend out from the fan module.
6. Slide the replacement fan module into the canister slot until it stops.
7. Simultaneously rotate both locking rings downwards through 90 degrees
while applying gentle pressure to push the fan module into the slot. The fan
module is installed correctly when the back edges of the locking rings are
flush with the relief detail inside the canister slot.
8. Replace the node canister into the canister slot until it stops.
