ESD Caution:

Circuit boards and drives contain electronic components that are extremely sensitive to static electricity. Ordinary amounts of static electricity from clothing or the work environment can destroy the components located on these boards. Do not touch the components along their connector edges.
Use a Antistatic Wrist strap. Attach one end of the strap to your wrist and the other end to the chassis, depending on what type of strap you use, with the adhesive end or the metal plug.
Use an Antistatic Mat. Place ESD-sensitive components such as motherboards, memory, and other PCBs on an antistatic mat.

Contamination Caution:

Dust particles of packaging material are number one cause of datacenter contamination. Make sure to remove all packaging material, up to the ESD safe packaging material, while still being outside the datacenter.

▼ Remove the Scalability Fans Cable
1. Use a grounding strap to protect the equipment from ESD damage.
2. Unpack and inspect the replacement cable.
Caution – Use an antistatic mat to protect the cable.
Note – For access to the cable, the server must be powered down so that the
components shown below can be removed.
3. Halt and power down the server.
See “Prepare to Power Off the Server” on page 54.
4. Remove the scalability card cage.
See “Remove the Scalability Card Cage” on page 147.

5. Undo four T20 Torx screws to remove the access panel from the side of the
scalability card cage.
Note – There are two scalability fan cables, one on the left side of the server and one
on the right. The replacement cable can be used for either side.
6. Reach into the opening to disconnect the cable.
Disconnect the two small connectors from the interior of the card cage. Disconnect
the large connector from the rear of the scalability card cage.
7. If you are removing both cables, repeat Step 5 and Step 6 for the second cable.

Install the Scalability Fans Cable
1. Use a grounding strap to protect the equipment from ESD damage.
2. If the side access panel has not already been removed, undo four T20 Torx
screws to remove the panel.
Note – There are two scalability fan cables, one on the left side of the server and one
on the right. The replacement cable can be used for either side.
3. Inside the opening, connect the large cable connector to the rear of the cage,
then connect the two small cable connectors to the small sockets inside the card
cage.
The connectors are not reversible.
4. Use four T20 Torx screws to attach the access panel.
5. If you are replacing both cables, repeat Step 2 through Step 4 for the second
cable.
6. Install the scalability card cage (item 3).
See “Install the Scalability Card Cage” on page 149.

7. Restart the server.
