Goal

 Description

Customers have reported that the Sun Fire[TM] E2900 Server takes a long time to power on. A considerable time passes before the LEDs indicate that the platform is powered on.

Solution

Steps to Follow

1) Power on the Sun Fire Server.

The system controller runs SCPOST.   If the system controller SCPOST level is set to max, this process takes approximately 20 minutes.  While SCPOST is running, there are no LEDs lit on the front panel.  

It is the responsibility of  ScApp to light these LEDs, and ScApp does not load until SCPOST finishes running.  It is particularly confusing that The  Source A & B  LEDs do not light until ScApp is loaded.

2) After powering on the platform, do the following:

a) Open the front doors, and you'll see the green LEDS flashing on the four PSUs.

       b) Look at Fan 3, which is spinning to provide cooling to the system controller.

3) Monitor the progress of SCPOST by establishing a connection to Serial Port A on the back of the server.

      When the lom shell prompt appears, the System Active and Source A & B  LEDs on the front panel are lit.

The SCPOST takes longer to run on a Sun Fire E2900 Server than on a Sun Fire[TM] V1280 because the Sun Fire E2900 ships with a version 2 system controller. This version has four times as much memory as the original system controller:

System Controller, Version 2 = 128 MB memory
System Controller, Version 1 = 32 MB memory

The bulk of the 20 minutes to run a max level SCPOST on a system
controller, version 2, is taken up by the memory tests:

POST Complete.

Although, you set SCPOST to the max level after replacing an
IB/SSC assembly, use the lom shell command setupsc to set it to
min.
