Installation Overview Installation and configuration of the Hotwire 799x endpoint consists of: Connecting power to the unit. Connecting to the network. Connecting to a DTE. Connecting a system terminal. Providing initial unit identity information or changing existing identity information. Configuring your unit using the Configuration Edit menus. Before you install the unit, read the Important Safety Instructions on page 30.
Connecting the Unit to an Optional External +24 or – 48 VDC Power Source Using the DC power cable, the unit is capable of operating on a +24 VDC or –48 VDC SELV power supply. Procedure To use the DC power cable for +24 VDC: 1. Connect the green wire to a suitable ground. 2. Connect the orange wire to the +24 VDC source. 3. Connect the white wire to the return. 4. Cut the black, red, and blue wires off at the outer insulation. 5. Plug the power connector into the unit.
Connecting to the Network Procedure To connect your unit to the network: 1. Connect one end of the supplied 8-position modular-to-8-position modular network cable into the rear panel DSL jack. 2. Connect the other end to your DSL network interface. NOTE: Do not use a flat VF network cable as this may severely degrade the performance of the unit. Use only Cat 5 twisted-pair network cable. Connecting to a DTE Model DTE Connection 7995 The synchronous interface is a 25-pin EIA-530-A interface.

Label Color LED is . . .* Indicating . . . POWER Green On Normal operation. Off No power to the unit. Slow Cycling Unit is in minimum mode and a download is required. ALARM TEST Red Yellow On Device failure, or self-test has failed. Off Self-test passed. On Loopback test in progress. Off No tests in progress.
Connecting to a System Terminal An optional system maintenance terminal may be attached to your Hotwire 799x endpoint through the modular jack on the rear panel. The system maintenance terminal allows you to view the status of the unit and change configuration options. The terminal must be a VT100-compatible terminal or a PC running terminal emulation software. Procedure To connect your unit to a system terminal: 1. Connect the 9-pin end of the supplied terminal cable into a COM port on your PC. 2.
