2-2 Installing and Connecting the Protection Switch DXC-100PSX
3. Connect the opposite end to the DB9 connector located on the DSMC.2 rear
interface module, marked PROTECT SWT.
4. Install the primary and redundant interface modules.
The DXC-100PSX Primary and Redundant Interface Module components are
sensitive to electrostatic discharge. When handling these modules, wear an
anti-static wrist strap connected to frame ground to prevent damage to circuits
from electrostatic discharge.
The Primary and Redundant Interface modules have a one-to-one
correspondence with the DXC-100 Interface modules; see
0 Table 2-1.

Narrowband Redundancy Connections
1. Connect the 50-pin cable from the network to the 50-pin connector on the
DXC-100PSX Narrowband Primary module.
5. Connect the 50-pin cable from the Narrowband Primary module to the
corresponding 50-pin connector on the DXC-100 Narrowband (D8E1T1) rear
interface module.
6. Attach the 50-pin male-to-male cable (CBL-100PSX-D8E1T1) from the
Narrowband Redundant module to the Standby slot 1 on the DXC-100.
