7.1 Verifying Power Supply Device Address
Before installing the hardware, provision the DHCP server with the cable modem’s CM MAC address.
This allows the installation to be verified while the technician is on-site, eliminating the need for a second
visit if there are problems with the installation.

To reduce the risk of electric shock, completely remove the Inverter Module from the power
supply prior to installation. For field installation, use a service power supply to avoid losing
power to the load.
The DSM3 Series is static sensitive. An ESD wrist strap should be worn when installing the
Communications Module.
CAUTION!
Before removing the Inverter Module (IM), verify the power supply device address is correct.
The power supply device address must
not be set to zero and no two power supplies monitored by a
single DSM3 Series can have the same address. The power supply must have a unique address to
communicate with a system controller. The system controller uses the address as an identifier to query
the power supply for information. Each power supply on the same communications bus must be identified
with a value between 1 and 5. To verify the power supply’s address do the following:
1. Press the PWR key on the Inverter Module twice to access the PWR CNFG Menu.
2. Press the Down or Up key until DEVICE ADDRESS is displayed.
3. If the address is correct (in the range of 1 to 5), skip to Step 8.
4. To change the address, press the Enter key to enter the Edit mode.
5. Press the Up or Down keys until the desired address (1 to 5) is displayed. Remember, each power
supply monitored by a single Communications Module must have a unique address; this may require
accessing the menu systems of the additional power supplies and adjusting as applicable.
6. Press the Enter key to load the new address.
7. Press ESC two times to return to the OPERATION NORMAL screen.
