4-8 SANnet II 200 SCSI Array Installation, Operation, and Service Manual • June 2005
Caution –
If the array is connected to DC power sources not within the designated
–48V DC (–36 VDC to –72 VDC) range, damage might occur to the unit.
Note –
To ensure power redundancy, be sure to connect the two power supply modules
to two separate circuits (for example, one commercial circuit and one UPS).
Note –
To extend the length of the DC power cable as needed, strip the last 1/4 inch
of the cable, insert the stripped end into a provided Panduit tube, and crimp the tube.
3. Tighten the cable locking screws to attach the cable securely to the power supply
power outlet.
4. Connect the second power cable to the second power supply and to a second power
outlet. Tighten the cable locking screws.
If one power supply fails, the second power supply automatically takes the full load.
