Connecting Modems to the Core Switch 2/64
Note: Setting up the modems before powering on the Core Switch 2/64 and
connecting it to the fabric is recommended.
The following items are required to set up two modems to work with the Core
Switch 2/64:
■
Two Hayes-compatible modems, such as the Zoom/Modem V.92 EXT Model
3049
■
Two standard modem cables, DB25 (male) to DB9 (female)
■
One RJ-11 Y adapter for standard telco wiring or equivalent circuitry (3 total
connections)
■
One analog telephone line
Caution: HP recommends powering off the Core Switch 2/64 before
connecting cables to the modem ports. HP also recommends powering off the
Core Switch 2/64 before connecting cables to the modem ports.
To connect modems to the Core Switch 2/64:
1. Optionally power off the Core Switch 2/64.
2. Set up the two modem units and corresponding power connections.
Note: Do not power on the modems until all cables are attached.
3. Connect the modem cables to the modems and to the Core Switch 2/64
RS-232 modem ports, as shown in Figure 46 .
4. Connect the telephone line inputs on the modems to the RJ-11 Y connector.
This effectively places both modems on a single telephone line.
5. Optionally connect a telephone handset to one of the phone connections on
the modems, as shown in Figure 46 .
