Alarm Connections
The chassis provides header connections to relay contacts that close/open upon the occurrence of
an alarm trap that the user configures as
critical
,
major
, or
minor
. These relay contacts
are available for the connection of user-provided alarm equipment that is external to the chassis.
The alarm relays have a rating of 24V at 1.5 A. Each relay has three contacts:
• N.O. (Normally Open)
• N.C. (Nornally Closed)
• C (Common)
The header connections use 0.045-inch square, 0.4-inch long wirewrap posts. Use five turns of 20
or 22 AWG wire, six turns of 24 AWG wire, or seven turns of 26 AWG wire for making connections
to these posts. Refer to
Table 2-10 for pinouts.
Status Input Connections
The chassis provides header connections for one or two status inputs from a user-provided external
device(s). When making a connection to the status inputs, a series resister (Rs) must be used to limit
current flow through the circuit. The value of the resistor is determined by the battery voltage used
in your specific installation. Refer to
Figure 2-11 for the recommended resistor values.
Refer to Table 2-10 for pinouts.

Module Installation
Refer to Chapter 3, Switch Fabric and V6.2 Controllers for procedures on how to properly install
and remove modules in and out of the Xedge 6640/6645 chassis.
Note
IMPORTANT! To avoid equipment damage, install only supported Xedge modules in appropriate slots of the
Xedge 6640/6645 chassis. Refer to
Table 1-1 and Table 1-4 before installing any modules.

If V
Batt
= 24 Vdc nominal, then Rs = 0 to 500 ohms.
If V
Batt
= 48 Vdc nominal, then Rs = 2500 to 4500 ohms.
