NOTE: The serial port and Telnet connection are mutually exclusive and there can be only one serial port session active at
a time. Telnet takes priority, so the serial port is terminated when a Telnet connection is made. The serial connection is
restored after the Telnet session is completed, but you must log in again. A password is required to log in to the serial
port session. Password checking is skipped only at initial power on and remains off until log off is done.
System Configurations
In order to communicate with the RS-232 port, a computer system is required with the following:
Hyper terminal
An available COM port
Cables: A straight-through serial cable (DB9 female-to-female) connected between the DB9 serial
ports on the computer and switch. See Table 1-2 for pinout requirements. This cable is included in the
over-pack, shipped with your PowerVault™ 50F switch.
Serial Cabling and Emissions Requirements
The PowerVault™ 50F Switch uses a straight-through serial cable with a female 9-pin D-Subminiature
connector with the pinouts shown in Table 1-2. Only pins 2, 3, and 5 are required.
