Troubleshooting Your System
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 printer, keyboard, mouse, or other external device). Ensure that all external
cables are securely attached to the external connectors on your system. See Figure 1-3 for the front-panel
connectors on your system and Figure 1-5 for the back-panel connectors.
Troubleshooting the Video Subsystem
Problem
• Monitor or monitor cable
• Keyboard/video/mouse (KVM) custom cable
• KVM module
• Server module
Action
1 Ensure that the server module(s) is turned on.
2 Check the monitor connection to the custom cable.
Try swapping monitor cables if another monitor cable is available.
3 Check the custom cable connection to either the front-panel custom-cable connector on the server
module or the back-panel KVM module.
4 If the monitor does not function from the back-panel KVM module, ensure that the KVM selection
indicator on the front panel of the server module is green. If not, press the KVM selection button. See
Figure 1-3.
NOTE:
See "KVM Modules" on page 22 for instructions on how to select a server module from the keyboard
connected to the KVM module.
