If the HP Server Powers On but Fails POST (Power-On Self Test)
Use this checklist to check for the following problems when the HP Server fails POST:
1. Clear CMOS and see if the HP Server boots.
Check the HP Server's reference label for instructions on clearing CMOS.
2. If the monitor is working, check the POST pass code it displays.
If the code is between #0 and 3Ah, and the code does not change,
a. Reseat the HP Server's memory boards and then reboot the HP Server.
b. Swap out the Legacy I/O Board and reboot the server
3. If clearing the CMOS does not solve the problem, refer to "If the HP Server Passes the Post but
Will Not Function" later in this chapter.
