LAN LEDs

There are four LAN LEDs on the front panel of the server blade. They are NIC 1 through NIC 4.
Table 21 details the functions of the LAN LEDs.

The following list itemizes the steps that characterize basic platform boot flow:
1. Server blade power switch requests power from the Management Module (the microcontroller
that manages the enclosure power and cooling). Once the power is request is granted, server
blade power turns on. After the power sequence has completed successfully, BMC releases
system reset.
2. Initial processor firmware code fetch is Platform Abstraction Layer (PAL) code from FEPROM
in processor-dependent hardware (PDH), retrieved 4 bytes at a time by the data
multiplexer/demultiplexer controller (DMDC) in zx1. No shared memory or I/O devices are
available at this time. They are not initially configured.
3. Firmware code stack is initially in battery-backed RAM (BBRAM) in PDH, retrieved 4 byes at
a time, through the PDH and DMD buses.

Normal Power-Up Through HP-UX Boot
No AC power to the server blade.
Server blade is shut down (server is off), AC power and
standby power is active, last health status was healthy.
Server blade power rails are on when Power switch is
toggled. Hardware drives power LED.
Server blade has powered up and is either at EFI, booting,
or at OS.
