2. If no LEDs on the control panel are working, replace the bezel assembly; then, try to
power-on the blade server from the Management Module Web interface. See the
Management Module User’s Guide for more information.
3. Turn off the blade server.
4. Remove the blade server from the Bull Blade Chassis - Enterprise and remove the
cover.
5. Remove or disconnect the following devices, one at a time, until you find the failure.
Reinstall, turn on, and reconfigure the blade server each time.
−
I/O expansion option.
− Hard disk drives.
−
Memory modules. The minimum configuration requirement is 2 GB (two 1 GB
DIMMs).
The following minimum configuration is required for the blade server to start:
− System-board and chassis assembly (with two microprocessors)
−
Two 2 GB DIMMs
− A functioning Bull Blade Chassis - Enterprise
6. Install and turn on the blade server. If the problem remains, suspect the following
components in order:
a.
DIMM
b. System-board and chassis assembly
If the problem is solved when you remove an I/O expansion option from the blade server
but the problem recurs when you reinstall the same expansion option, suspect the
expansion option; if the problem recurs when you replace the expansion option with a
different one, suspect the System-board and chassis assembly.
If you suspect a networking problem and the blade server passes all the system tests,
suspect a network cabling problem that is external to the system.
