Serial port

The 8/20q Fibre Channel Switch is equipped with an RS-232 serial port for maintenance purposes

(Figure 6). You can manage the switch through the serial port using the CLI.

Figure 6 Serial port and pin identification

The serial port connector requires a null-modem F/F DB9 cable. The pins on the switch RS-232 connector

(Figure 6) are identified in Table 2. For information about connecting the workstation through the serial

port, see ”Connect the management station or workstation to the switch” on page 35.

Power supply and fans

The switch has a single power supply that converts 100–240 VAC to DC voltages for the various switch

circuits. Four internal fans provide cooling. The switch monitors internal air temperature, and therefore does

not monitor or report fan operational status. Air flow is front-to-back. To energize the switch, plug the

power cord into the switch AC receptacle (located on the back of the switch) and into a 100–240 VAC

power source.
