3Connect the other end of the power wire to the positive terminal on the power supply.

4Connect one end of a power wire to the Switch’s -48V(input) pin and tighten the captive screw.

3.2.6External Backup Power Supply Connector

The Switch supports external backup power supply (BPS).

The Switch constantly monitors the status of the internal power supply. The backup power supply automatically provides power to the Switch in the event of a power failure. Once the Switch receives power from the backup power supply, it will not automatically switch back to using the internal power supply even when the power is resumed.

3.2.7 Console Port

For local management, you can use a computer with terminal emulation software configured to the following parameters:

VT100 terminal emulation

9600 bps

No parity, 8 data bits, 1 stop bit

No flow control

Connect the male 9-pin end of the RS-232 console cable to the console port of the Switch. Connect the female end to a serial port (COM1, COM2 or other COM port) of your computer.
