Checking external devices
Ensure that you complete an external device check before you install or service the system.
Procedure
To conduct an external device check, complete the following steps.
1. Verify that all external covers are present and are not damaged.
2. Ensure that all latches and hinges are in the correct operating condition.
3. Check the power cords for damage.
4. Check the external signal cables for damage.
5. Check the cover for sharp edges, damage, or alterations that expose the internal parts of the device.
6. Correct any problems that you find.
Checking internal devices
Ensure that you complete an internal device check before you install or service your system.
About this task
To conduct the internal device check, use the following steps.
Procedure
1. Check for any non-IBM changes that were made to the device. If any are present, obtain the “Non-IBM
Alteration Attachment Survey,” form number R009, from the IBM branch office. Complete the form
and return it to the branch office.
2. Check the condition of the inside of the device for any metal or other contaminants, or any indications
of water, other fluid, fire, or smoke damage.
3. Check for any obvious mechanical problems, such as loose components.
4. Check any exposed cables and connectors for wear, cracks, or pinching.
Checking the grounding of a system
Ensure that you understand how to check the grounding of a system.
About this task
To test the grounding of a system: Follow the steps for the system configuration that you are using. Before
you start, confirm that you know the system model type. Determine the location of the signal cables that
are attached to the system.
When you are asked to test the grounding continuity, use your local procedures to initiate the test. The
test is successful if the measured resistance is 0.1 ohm or less.
Attention: Some electrical circuits can be damaged if the external signal cables are present at the
node while it is undergoing a grounding test.
Procedure
1. Ensure that the node is powered off. See MAP 5350: Powering off a SAN Volume Controller node in the
IBM SAN Volume Controller Troubleshooting Guide .
2. Disconnect all signal cables from the node, which includes the following cables:
• The Fibre Channel cables
• The Ethernet cable or cables
3. Disconnect the power cable from the site power-distribution unit.
4. Disconnect both input power leads from the site power distribution units.
