Powering On the Server

When all the power cables are connected and the external circuit breakers are switched on, the server enters Standby mode. The Source A and Source B indicators are the only indicator LEDs to be illuminated on the system indicator board. The IB_SSC assembly Active LED is lit, but not visible from the front of the server.

Powering the server on from Standby mode can be achieved in either of two ways:

Operating the On/Standby switch

Sending the poweron command via the LOM port

The On/Standby switch of the Netra 1290 server controls only low voltage signals and no high voltage circuits pass through it.

Note – The power switch is not an On/Off switch, it is an On/Standby switch. It does not isolate the equipment.

Once the server is powered on, if the auto-boot?variable has been set true in the OpenBoot PROM, the server will automatically boot into the Solaris Operating System.

To Power On Using the On/Standby Switch

1.Check that power is applied to the server and that it is correctly in Standby mode.

2.Momentarily press the On/Standby switch to the right.
