1U Rackmount System

Power Supply Fail LED Header

Connect a cable from your power sup- ply to JPWF to

provide a warning of power supply failure. This warn-

ing sig- nal is passed through the PWR_LED pin to

indicate of a power failure on the chassis. See the

table on the right for pin definitions.

Alarm Reset

If three power supply modules are installed, the

system can notify you when any of the three fails.

Connect JAR to a micro-switch to enable you to turn

off the alarm that is activated when a power module

fails. See the table on the right for pin definitions.

I-Button

The I-Button, located near the floppy connector, is a

computer chip en- closed in a durable stainless

contain- er to enable RAID 5 under Software R AID

mode. See the table on the right for pin definitions.

Unit Identifier Button

There are three Unit Identification (UID) devices on

the motherboard. A rear UID switch and a rear UID

LED indicator. The Front Panel UID LED is connected

to a pin in the Front Control Panel (Pin 7 of JF1).

When the user pushes the rear UID switch, the Front

Panel UID LED and the backplane UID LED (LE5) will

turn on. Push the rear UID switch again to turn off both

Indicators. These UID Indicators provide easy identifi-

cation of a system unit that may be in need of service.
