The recommended ways to mount the chassis are as
follows:
• Flush-mount: To flush-mount a Total Access 1500
19-Inch Chassis in the rack, use a #2 phillips-head
screwdriver and attach the mounting brackets (see
Figure 2) with the flanges containing the slotted
rack-mounting holes facing the front of the Total
Access 1500 19-Inch Chassis. The mounting brack-
ets should be attached using the set of mounting
bracket holes closest to the rear of the Total Access
1500 19-Inch Chassis.

• Mid-mount: To mid-mount a Total Access 1500 19-
Inch Chassis in the rack, use a #2 phillips-head
screwdriver and attach the mounting brackets (see
Figure 3) with the flanges containing the slotted
rack-mounting holes facing the rear of the Total
Access 1500 19-Inch Chassis. The mounting brack-
ets should be attached using the set of mounting
bracket holes closest to the front of the Total Access
1500 19-Inch Chassis.

Installing the Chassis
After attaching the mounting brackets to the Total
Access 1500 19-Inch Chassis sides, use the appropriate
screws for the CO rack type and mount the chassis in the
rack as follows:
1. Flush-mount: For flush-mount systems, the Total
Access 1500 19-Inch Chassis must be mounted
from the rear of the rack, with mounting bracket
flanges facing rearward.
2. Mid-mount: For mid-mount systems, the Total
Access 1500 19-Inch Chassis must be mounted
from the front of the rack, with the mounting
bracket flanges facing forward.
NOTE
Other orientations will require either mounting
from the front or rear, and depend on the rack
type installed in the CO and the standard
operating procedures established by the CO.
Once the orientation of the chassis has been determined,
use the four appropriate screws for the CO rack and an
appropriate screwdriver and secure the Total Access
1500 19-Inch Chassis in place on the rack.
Connections
Interconnections between the common modules and
channel units are accomplished through the backplane
PCB. All external connections to the Total Access 1500
19-Inch Chassis are through connectors and wire-wrap
headers located on the backplane.
NOTE
When connecting power and ground wiring, be
sure to follow all local, national, and company
codes.
