Figure 1-10. Connections for PowerVault 51F Switch

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.
NOTICE: The serial port is intended for initial configuration of the IP
address or disaster recovery only and not for regular maintenance. Dell
recommends removing the serial port cable for normal (non-configuration,
non-recovery) switch operation.
NOTICE: Password checking is skipped only at initial power on to allow you
to log into the switch before you set the password. If you have forgotten the
password, you can reset the switch to factory default values.

System Configurations

A computer system must have the following components to communicate with the
RS-232 port:
•
HyperTerminal
•
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 shipped with your PowerVault 51F switch.

Serial Cabling and Emissions Requirements

The PowerVault 51F switch uses a standard 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. Pin 7 , if used, must always be driven high.
