Remote Supervisor Adapter
1. Insert the Remote Supervisor Adapter Support CD-ROM into the CD-ROM drive
and restart the NAS Gateway 300. If the NAS Gateway 300 does not boot from
the CD-ROM, use POST/BIOS setup to configure the CD-ROM drive as a boot
device.
After the NAS Gateway 300 boots, the main menu displays.
2. Use the Up and Down arrow keys to select Hardware Status and Information
and press Enter . The Hardware Status and Information menu reports on the
Advanced System Management devices in the NAS Gateway 300 in the
following manner:
System Management Processor Communication : Passed

Power checkout
Power problems can be difficult to troubleshoot. For example, a short circuit can
exist anywhere on any of the power-distribution busses. Usually a short circuit
causes the power subsystem to shut down because of an overcurrent condition.
A general procedure for troubleshooting power problems is as follows:
1. Shut down (see “Shutting down and powering on the NAS Gateway 300” on
page 87) the system and disconnect the ac cords.
2. Check for loose cables in the power subsystem. Also check for short circuits; for
example, a loose screw could cause a short circuit on a circuit board.
3. Remove adapters and disconnect the cables and power connectors to all
internal and external devices until the NAS Gateway 300 is at minimum
configuration required for power-on (see “Minimum operating requirements” on
page 152).
4. Reconnect the ac cord and power on the NAS Gateway 300. If it powers up
successfully, replace adapters and devices one at a time until the problem is
isolated.
For specific power problems, see “Power error messages” on page 148.
