Setting Up and Installing Modems Connecting Modems The following items are required to set up two modems to work with the SAN Director 2/128: ■ 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 (three total connections) ■ One analog telephone line Note: Setting up the modems before powering on the SAN Director 2/128 and connecting it to the fabric is recommended. To connect modems to the SAN Director 2/128: Caution: Powering off the SAN Director 2/128 before connecting cables to the modem ports is recommended. 1. Power off the SAN Director 2/128. 2. Set up the two modem units and corresponding power connections, but do not power on the modems until all cables are attached. 3. Connect the modem cables to the modems and to the SAN Director 2/128 RS-232 modem ports. 4. Connect the telephone "line" inputs on the modems to the RJ-11 "Y" connector. 5. This effectively places both modems on a single telephone line. 6. Optionally connect a telephone handset to one of the "phone" connections on the modems. 7. Connect the "Y" adapter to an appropriate analog telephone line and document the dial-in number for later use. 8. Power on the modems and verify that the Modem Ready indicator illuminates on both units. 154 SAN Director 2/128 Installation Guide
