310 Troubleshooting Your System
Checking the Equipment
This section provides troubleshooting procedures for external devices
attached to the system, such as the monitor, keyboard, or mouse. Before you
perform any of the procedures, see "Troubleshooting External Connections"
on page 310.
Troubleshooting External Connections
Loose or improperly connected cables are the most likely source of problems
for the system, monitor, and other peripherals (such as a keyboard, mouse, or
other external device). Ensure that all external cables are securely attached to
the external connectors on your system. See Figure 1-13 for the front-panel
connectors on your system and Figure 1-15 for the back-panel connectors.
Troubleshooting Video
1 Check the connection to the iKVM module.
Try swapping cables if another monitor cable is available.
2 Verify that the iKVM firmware revision is current.
3 Check the monitor connection to either the front-panel connector on the
blade or the back-panel iKVM module.
4 Ensure that the port is not disabled by the CMC or by redirection to
another port.
5 If two or more blades are installed in the enclosure, select a different blade.
If the monitor is connected to the back-panel iKVM module and works
with another blade, the first blade may need to be reseated. See "Removing
and Installing a Blade" on page 155. If reseating the blade does not help,
the blade may be faulty. See "Getting Help" on page 361.
6 Swap the monitor with a known-working monitor.
If the monitor does not work when connected to the blade front-panel
connector, the blade may be faulty. See "Getting Help" on page 361.
If the monitor does not work when connected to the iKVM module, the
iKVM module may be faulty. See "Getting Help" on page 361.
