CHAPTER 5: Configuration and Operation
5.9 Connecting Multiple SCSI Switches
Up to thirty-two SCSI Switches can be controlled by a single RS-232 serial interface.
To operate in this configuration, set the serial ports to operate in daisychained
mode. In Figure 5-6, “1” is RS-232 port 1 on each switch and “2” is RS-232 port 2.
Figure 5-4. Multiple SCSI Switch configuration.
5.10 Rackmount Installation
The 6 x 4 Electronic SCSI Switch can be installed in a standard 19-inch (EIA unit)
rack.

ONSIDERATIONS
1.
For proper operation, make sure that the maximum recommended
operating ambient temperature of 149°F (65°C) is not exceeded. Keep in
mind that if the unit is installed in a closed or multi-unit rack assembly, the
operating ambient temperature of the rack environment may be greater
than room ambient. Install the rack in an environment compatible with the
SCSI Switch’s maximum rated operating temperature.
2.
Make sure that the amount of airflow around the SCSI Switch that’s required
for safe operation is not compromised.
