Chapter 1 Netra 1290 Server Overview 7
Power Failure
On recovery from a power outage, the SC attempts to restore the system to its
previous state.
System Controller Reboot
The SC can be rebooted and will start up and resume management of the system.
The reboot does not disturb the currently running Solaris Operating System.
Host Watchdog
The SC monitors the state of the Solaris Operating System and initiates a reset if the
system stops responding.
Serviceability
The software serviceability features promote the efficiency and timeliness of
providing routine as well as emergency service to the server.

LEDs
All field-replaceable units (FRUs) that are accessible from outside the server have
LEDs that indicate their state. The SC manages all the LEDs in the server, with the
exception of the power supply LEDs, which are managed by the power supplies. For
a discussion of LED functions, see the
Netra 1290 Server Service Manual , 819-4373.
Nomenclature
The SC, the Solaris Operating System, the power-on self-test (POST), and the
OpenBoot™ PROM error messages use FRU name identifiers that match the physical
labels in the server. The only exception is the OpenBoot PROM nomenclature used
for I/O devices, which use the device path names as described in
Chapter 4 to
indicate I/O devices during device probing.
