Troubleshooting the DRAC/MC Module Problem • DRAC/MC module is not operating properly • System message indicates a problem with the DRAC/MC module • DRAC/MC module cable connections Action NOTE: To eliminate the possibility of a hardware problem with the module or its attaching devices, first ensure that the module is properly initialized and configured. See the Configuration Guide and the documentation that came with the module before performing the following procedure. 1 Reseat the DRAC/MC module and see if the DRAC/MC module fault indictor turns off. See "DRAC/MC Module" on page 61. See Figure 1-10 for more information about the module's indicators. 2 If another DRAC/MC module is available, swap the two modules. 3 If the fault indicator is off, but the serial device connected to the serial port is not properly operating, go to step 4. If the fault indicator is off, but the network management device connected to the network interface connector port is not properly operating, go to step 8. 4 Ensure that the serial cable is a null modem cable. 5 Reseat the serial cable to the serial connector on the DRAC/MC module and to the serial device. 6 Connect a known-working null-modem serial cable between the DRAC/MC module and the serial device. 7 Connect a known-working serial device to the DRAC/MC module. If the serial device and DRAC/MC module still do not communicate with each other, see "Getting Help" on page 127. 8 Reseat the network cable to the network connector on the DRAC/MC module and to the network device. 9 Connect a known-working network cable between the DRAC/MC module and the network device. 10 Connect a known-working network device to the DRAC/MC module. If the network device and DRAC/MC module still do not communicate with each other, see "Getting Help" on page 127. Troubleshooting Your System 109

Troubleshooting the DRAC/MC Module
Problem
•
DRAC/MC module is not operating properly
•
System message indicates a problem with the DRAC/MC module
•
DRAC/MC module cable connections
Action
NOTE:
To eliminate the possibility of a hardware problem with the module or its attaching devices, first ensure that
the module is properly initialized and configured. See the
Configuration Guide
and the documentation that came
with the module before performing the following procedure.
1
Reseat the DRAC/MC module and see if the DRAC/MC module fault indictor turns off. See
"DRAC/MC Module" on page 61. See Figure 1-10 for more information about the module’s indicators.
2
If another DRAC/MC module is available, swap the two modules.
3
If the fault indicator is off, but the serial device connected to the serial port is not properly operating,
go to step 4. If the fault indicator is off, but the network management device connected to the network
interface connector port is not properly operating, go to step 8.
4
Ensure that the serial cable is a null modem cable.
5
Reseat the serial cable to the serial connector on the DRAC/MC module and to the serial device.
6
Connect a known-working null-modem serial cable between the DRAC/MC module and the serial
device.
7
Connect a known-working serial device to the DRAC/MC module.
If the serial device and DRAC/MC module still do not communicate with each other, see "Getting
Help" on page 127.
8
Reseat the network cable to the network connector on the DRAC/MC module and to the network
device.
9
Connect a known-working network cable between the DRAC/MC module and the network device.
10
Connect a known-working network device to the DRAC/MC module.
If the network device and DRAC/MC module still do not communicate with each other, see "Getting
Help" on page 127.
