Cabling an AccessWay Enclosure (continued)
Step
3. If you plan to configure modems by issuing commands:
• Directly to each modem: connect a shielded cable from a
computer's serial port to a modem DTE connector. (After
configuring a modem, move the connector to another modem.)
• With Fast'RVu over a direct cable connection, or with a locally
attached Motorola network management system (NMS):
connect the shielded NMS cable from the computer or NMS's
serial port to the enclosure's NM IN connector. In enclosures
with mass-termination telephone connectors, install a ferrite
bead on each NMS cable, near the AccessWay panel. Pass the
cable through the bead twice, with one full turn.
• With Fast'RVu over a secondary-channel connection, you do
not need a special cable connection.
4. Optionally, on DC powered enclosures, install a second DC
power module. Installation is described later in this chapter.
5. Connect the power cable from the AccessWay rear panel to a
power source. The enclosure is factory-configured for one
power input type: AC or DC. Your power source must match.
All cables should be emissions-shielded.
Figure 1-7 shows how to attach a ferrite bead to a mass-termination
multi-line telephone cable.
