5. Initial Start-up and Test.
Plug the power supply into the AC outlet and turn on the battery breaker (XM2-HP units perform a 10-second self test to check the
batteries).
The DSM2 LEDs blink three times and the RDY light begins blinking on and off.
Verify the DS and REG LEDs are on solid. This verifies that the DSM2 has registered an IP address on the public network.
Verify LNK LED is flashing in Single IP mode, or ON
solid in Dual IP mode.
Verify no XM2 alarms are active.
6. Test the Connection.
With the DSM2 used in conjunction with the XM2-HP power supply, connectivity can be verified via the XM2-HP smart display.
Otherwise, test the connection with a personal computer and a Local Port Adapter Cable (Alpha P/N 745-826-21). Terminal
Emulation software is necessary (e.g., HyperTerminal). Serial communication settings are:
Baud: 19200; Data Bits, 1; Parity, None; Stop Bits, 1; Flow Control None
To test the connection, launch the terminal emulation software and press ENTER.
3. Make Battery Sense Wire Kit connections.
See the battery diagrams that came with the sense wire kit or reference the DSM2 Technical Manual.
4. Connect the RF drop and make front panel connections.
The DOCSIS specification for downstream power level is ± 15dBmV. However, for optimal performance, set the level as close to 0
dBmV as possible.

MAIN>
The procedure shown at left will allow you to see MAC
addresses, useful in working with network registration. IP
addresses can help determine if the transponder is recognized
by the management system, and if the transponder is in single
or dual IP operation (in dual IP, the CPE and CM will have an IP
address; in single, only the CM will have an IP address). Correct
battery voltages verify that the battery sense cable is connected
properly. Cable modem transmit and receive levels will be
helpful in verifying proper padding at the RF drop.
