System Lan Leds; Troubleshooting The Boot Process - HP Integrity rx2800 - i2 User's & Service Manual

a. Turn off the server power button and unplug the ac power cords and any cables.
b. Re-seat all of the SAS disk drives installed in the server.
c. Reconnect the ac power cords and any cables. Restart the server to determine whether
the LEDs now become illuminated during the boot. If not, contact your reseller.
4. Use the UEFI Shell info io command to check the SCSI drives.

System LAN LEDs

There are four system LAN LEDs on the rear bulkhead of the server. These LANs are connected to
the system board.

Troubleshooting the boot process

Table 45 shows the normal boot process, as reflected in changes to front panel LED states:

NOTE: In the normal boot process, shown in the preceding table, even though the BMC is running
while the system is shut down (power LED is steady amber), it doesn't drive the external health LED
to steady green until +12 V dc power from the Bulk Power Supplies is applied.
The following list itemizes the steps that characterize basic platform boot flow. Step numbers
provided correspond to the steps in
3) System power switch turns on bulk power supplies and fans, and releases RESET on all CPUs
simultaneously, when toggled on.
5) Initial CPU firmware code fetch is PAL code from EEPROM in PDH, retrieved 4 bytes at a time
by DMDC in ICH10 (No shared memory or I/O devices are available at this time; for example
they are not initially configured).
