Basic and Advanced Troubleshooting Tables

Use the following troubleshooting tables to determine the symptoms or condition of a suspect server

blade. Be aware that the state of the front panel LEDs can be viewed locally; or remotely using the

vfp command from the MP.

The tables are designed to cover troubleshooting symptoms from AC power-on up to booting the

OS, specifically in Steps 1-5. In most cases, Table 12: “Basic Front Panel LED Troubleshooting

States”, identifies the step number where troubleshooting should begin. Alternatively, you can skip

Table 12, and start with Step 1 in Table 13: “Basic Low End Troubleshooting”, sequencing through

the table steps to locate the symptom/condition most descriptive of your current server blade status.

This becomes the first step in your troubleshooting procedure. Where appropriate, an action or

actions prescribed in the Action column of Table 13: “Basic Low End Troubleshooting”, is followed

by a reference to the corresponding subsection of this chapter for further information.

NOTE: In Table 12, the Unit Identifier (UID)/Locator LED has not been included, because it is

not used directly for troubleshooting server blades. However, indirectly, it can provide useful system

information (for example when it is blue, this indicates the BMC is working). It also indicates the

server blade which has an error or fault condition by illuminating steady blue on the front of the

server blade in question.

Nothing is logged for this condition.Server blade appears “dead” -- no front panel

LEDs are on, and no fans are running. BMC and

iLO 2 MP are running.

1. For new server installations, review the installation

procedures.

2. Verify that the enclosure power cord(s) are connected

to both the power supplies and to the AC receptacle(s).

3. Verify that AC power, at the proper AC voltage levels,

is available to the receptacle(s).

4. If the Power button’s integrated LED on front panel

remains off, then reseat the server blade.

5. As a last resort, replace the server blade. The preceding

problem is fixed when the front panel LED states are as

follows: Server health is off and Internal health is steady

amber.

A fatal fault has been detected and logged, attempting to

power on the server.

LED (UID) can be turned on or off through the

system console.

2. If the enclosure power supply LED is green, then you

may need an additional power supply to supply sufficient

power to run the blades in the enclosure.
