Unit ID Switch

There are three Unit Identiﬁ cation

(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

control panel (pin 7 of JF1). When

the user pushes the rear UID switch,

the control panel UID LED and the

back panel 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.
