|---|---|
1 | Major alarm: normally open |
2 | Major alarm: common |
3 | Major alarm: normally closed |
4 | Visual alarm: normally open |
5 | Visual alarm: common |
6 | Visual alarm: normally closed |
7 | Unused |

Note The cable and connector assembly should be fully shielded. |
The DS3 interface uses SMB connectors for separate transmit and receive coaxial cables. Use commercially available cable and connector assemblies for all DS3 connections. These cables have the following characteristics:
The management and Fast Ethernet interfaces require Category 5 shielded twisted pair cables terminated with RJ-45 connectors. Pin assignments for the RJ-45 connectors are shown in Table A-2.

The console and auxiliary ports use EIA/TIA-232 serial cables with DB-9 connectors. Use shielded multiconductor type cables.
The console interface uses a DTE type cable (null modem).
The auxiliary interface uses a DCE type cable (straight through).
|
Note The auxiliary port supports full modem handshaking when connected to the serial port of an external modem. |
The console and auxiliary connectors have the pin assignments shown in Table A-6.
