The HP SureStore E Carrier-Grade Disk System SC10 contains a
NEBS-compatible direct current (DC) power supply, rather than the

E Disk System SC10.
This DC power supply directly replaces the standard AC supply for the
purpose of operating this storage device from a central office negative 48
volt or negative 60 volt power source.
The power supply also provides alarm outputs in the form of relay
contact closures to indicate a power supply failure.
1.) The power supply cable is used as the main disconnect device
for this equipment.
2.) Make sure that all central office safety precautions are
carefully observed when connecting the power supply to the DC
power source.
3.) This product is to be installed only in Restricted Access Areas
(dedicated equipment rooms, equipment closets or the like) in
accordance with Articles 110-16 to 110-18 of National Electrical
Code, ANSI/NFFA 70.

personnel.
