Upgrading Firmware

You can use a local computer that connects to the unit through the serial

port on the front panel of the unit.

1. Select a serial port at the local computer, and disable any service

which uses that port.

2. Use the supplied smart-signaling cable (940-0024C) to connect the

selected port to the serial port on the front panel of the unit.

3. Run a terminal program (such as HyperTerminal) and configure the

selected port for 2400 bps, 8 data bits, no parity, 1 stop bit, and no flow

control. Save the changes.

4. Press

ENTER twice to display the User Name prompt.

5. Enter your user name and password (both apc, for administrators only)

and press the Enter key.

6. From the Control Console menu, select System, then Tools, then

XMODEM.

7. At the prompt Perform transfer with XMODEM-CRC? type yes,

and press

ENTER.

8. The system will then prompt you to choose a transfer rate and to

change your terminal settings to match the transfer rate. Press

ENTER

to set the MasterSwitch Plus to accept the download.

Upon completion of the transfer, the console will prompt you to restore
