If the system does not power on, check the LED display. If the power LED
is not on, you may not be receiving AC power. Check the AC power cord to
make sure that it is securely connected.
Troubleshooting System Startup Failure
If your system halts during startup, especially after installing an operating
system or reconfiguring your system's hardware, check for invalid memory
configurations. These could cause the system to halt at startup without any
video output. See the compute sled's Hardware Owner's Manual for
information about the "System Memory".
For all other startup issues, note any system messages that appear onscreen.
See "Using the System Setup Program" on page 67 for more information.
Troubleshooting External Connections
Ensure that all external cables are securely attached to the external
connectors on your sled before troubleshooting any external devices.
See Figure 1-1 and Figure 1-3 for the front- and back-panel connectors
on your system.
Troubleshooting the Video Subsystem
1 Check the compute sled and power connections to the monitor.
2 Check the video interface cabling from the compute sled to the monitor.
Troubleshooting a USB Device
Use the following steps to troubleshoot a USB keyboard and/or mouse. For
other USB devices, go to step 5.
1 Ensure that the compute sled is turned on.
2 Disconnect the keyboard and mouse cables from the sled briefly and
reconnect them.
3 If the problem is resolved, restart the sled, enter the System Setup
program, and check if the nonfunctioning USB ports are enabled.
4 Swap the keyboard/mouse with a known-working keyboard/mouse.
