end of the power cord to the rear panel on the switch and the other end
to a power outlet.
In this configuration, the internal supply provides power. If the internal
supply fails or is switched off, or if there is a power failure, the RPS is
activated and the switch reboots.
To reset a switch in this configuration, turn the power off, wait 5 seconds
and turn it back on. The switch switches to the RPS, then switches back
to the internal supply to reboot.
CAUTION: For system susceptibility protection, always leave the AC cord
attached to the switch and to a power outlet.
Internal power supply failure is rare. If it occurs, the power switch on your
switch will not operate. To reboot, unplug the RPS cable and then plug it
back in. Replace your switch with another switch that has a functioning
internal power supply as soon as possible. Contact your 3Com
representative to replace your switch.
Connecting a PC,
Terminal, or
Modem
Connect a PC running a terminal emulation program, a terminal, or a
modem to the console port on the PathBuilder switch to configure the
switch software and review startup and system operation messages.
To connect a PC, terminal, or modem to the switch, follow these steps:
1 Obtain a cable to connect the device to the console port on the switch.
See “Console Connector and Cables” on page 83 for cable pinouts.
The console port is a 9-pin male connector.
For the PC, use a 9-pin female to 9-pin female null modem-type cable.
For the terminal, use a 9-pin female to 25-pin null modem-type cable.
For the modem, use a 9-pin female to 25-pin male straight-through-type
cable.
2 Connect one end of the cable to the console port on the PathBuilder
switch and the other end to the serial port on the back of your device.
