Alarm Relay Connector
The access carrier provides one independent alarm relay for a system alarm light or
buzzer. This relay uses SPDT (Single Pole Double Throw) contacts (common, normally
open, and normally closed). After making any necessary connections to your alarm
system, plug the connector that you received in the box with the access carrier into the
socket on the power I/O card.
NAM Fan Tray
A fan tray for the NAMs is used so that the ambient temperature remains within the
acceptable range. A replacement fan tray is available as a separately orderable product.
Once the carrier is connected to AC power, the fans in the fan tray begin circulating air
and the green LED lights. If not, check potential reasons in
Troubleshooting in the
appropriate product manual.
Installing the Baffle
A baffle with self-retaining nuts is provided for heat deflection. Extender brackets are
also provided to convert the baffle for use in a 23-inch rack.
Procedure
1. If installing the baffle in a 23-inch rack, attach the two extender brackets to each
side of the baffle using four of the self-retaining nuts (#12-24) and four of the screws
(#12-24 x 1/2-inch) provided.
2. If the rack does not have threaded screw holes, slip a self-retaining nut onto the first
available hole on each side of the rack beneath the installed carrier. Align the hole
of the nut with the hole in the rail.
