Removing and replacing the external HMC cable in the

9008-22L, 9009-22A, or 9223-22H

Find information about removing and replacing the external HMC cable in the 9008-22L, 9009-22A, or

9223-22H.

Preparing the system to remove and replace the external HMC cable

To prepare the system to remove and replace the external HMC cable, complete the steps in this

procedure.

Procedure

Removing the external HMC cable from the 9008-22L, 9009-22A, or

9223-22H

To remove the external HMC cable, complete the steps in this procedure.

Procedure

1. Attach the electrostatic discharge (ESD) wrist strap. The ESD wrist strap must be connected to an

unpainted metal surface until the service procedure is completed, and if applicable, until the service

access cover is replaced.

Attention:

vAttach an electrostatic discharge (ESD) wrist strap to the front ESD jack, to the rear ESD jack, or to

an unpainted metal surface of your hardware to prevent the electrostatic discharge from damaging

your hardware.

vWhen you use an ESD wrist strap, follow all electrical safety procedures. An ESD wrist strap is

used for static control. It does not increase or decrease your risk of receiving electric shock when

using or working on electrical equipment.

vIf you do not have an ESD wrist strap, just prior to removing the product from ESD packaging and

installing or replacing hardware, touch an unpainted metal surface of the system for a minimum of

5 seconds. If at any point in this service process you move away from the system, it is important to

again discharge yourself by touching an unpainted metal surface for at least 5 seconds before you

continue with the service process.

2. Disconnect the HMC cable indicated in the FRU Location field in the upper left of this page. See

Figure 1.

Figure 1. Removing an HMC cable

Replacing the external HMC cable in the 9008-22L, 9009-22A, or

9223-22H

To replace the external HMC cable, complete the steps in this procedure.

Procedure

1. Ensure that you have the electrostatic discharge (ESD) wrist strap on and that the ESD clip is plugged

into a ground jack or connected to an unpainted metal surface. If not, do so now.

2. Connect the HMC cable indicated in the FRU Location field in the upper left of this page. See

Figure 2.
