Modem Installation

Network Management System Connection

For the Model 3910, use the following procedures to connect the modem to the network management system interface:

1.Insert the sub-miniature, 4-conductor modular plug of the 3600 Hubbing Device into the jack labeled NMS (Figure 2-1). Refer to Document Number, 3610-A2-GZ45,

3600 Hubbing Device Feature Number 3600-F3-300, Installation Instructions, for a description of the 3600 Hubbing Device. Installation for the 3910 is the same as for the 3610 DSU.

2.Connect the 3600 Hubbing Device to the network management channel (Figure G-4 in Appendix G).

Power Supply Connection

Use the following procedures to connect the modem to an ac power outlet:

1.Make sure the modem's power switch is in the OFF position.

2.Insert the power supply's 8-pin DIN connector into the modem's rear panel dc power receptacle (Figure 2-1).

3.Connect the power supply to a grounded ac power outlet.

Modem Power-Up

Once your modem is properly connected to the power supply, leased and/or dial lines, and the DTE, press the modem's rear panel power switch to the ON position. The modem begins a power-up self-test, in which all DCP LEDs light. This test takes several seconds to perform, and verifies the operation of most hardware components within the modem. If successful, the LCD displays Power on Selftst Passed and continues to the Top-Level menu screen.

If a failure occurs during the self-test, the LCD displays Power On Selftst Failed for several seconds. The LCD then displays the Top-Level menu screen with the message Power on Fail appearing on the top line of the LCD. Although a failure has occurred, the modem will attempt to operate. This allows you to activate a more thorough self-test using the Test branch. Refer to the Test section in Chapter 3.
