Chapter 3 Hardware Overview
3.2.2 External 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.
3.2.3 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
