2.4.3 Installing the DS-BA356-SG UltraSCSI Hub 41U RETMA
Shelf Mounting Kit
The UltraSCSI Hub Shelf option is installed in a 41U RETMA cabinet using the BA356
shelf mounting kit. The kit allows you to install up to two 3-port or 5-port SCSI Hubs in
either the front and/or the rear of a cabinet containing 41 U RETMA mounting rails. The
height of the shelf is approximately 150 mm (5.9 in.).
High voltages are present within the cabinet when power is
applied. Always turn off ac power to the cabinet and
disconnect the power cords from the wall outlet before
proceeding with this procedure.
Also, the rail edges in the cabinet are very sharp. Never
slide hands along cabinet rail edges.
Proceed as follows to install the shelf mounting kit into the cabinet:
1. Turn off all ac power to the cabinet and disconnect the power cords.
