3.3 Connection to Alarm Contacts

The alarm contacts for the 9101 LAN Chassis are located in the middle of the upper
portion of the chassis and are shown in Figure 3-7. A set of alarm contacts is
associated with each power supply.

NOTE: The alarm contacts located on the rear of the 9101 LAN Chassis are

relay contacts that either open or close a circuit. They can therefore be
used to close a circuit allowing current to flow to an alarm or alert
system or indicate a logical 1 or 0 through the presence or absence of a
voltage.

NOTE: An external Chassis Ground connection can be accessed via the back

side of the 9101 Chassis, as referenced in Figure 3-7.
