IBM SAN768B, Installation, Service And User Manual

Page: 171 / 208

Facility requirements
The facility where the SAN768B is in use must meet the following requirements to
provide for correct operation:
v Adequate supply circuit, line fusing, and wire size, as specified by the electrical
rating on the chassis nameplate
v
An air flow of at least 595 cubic meters per hour (350 cubic feet per minute),
available in the immediate vicinity of the SAN768B
v The power specifications listed in Table 23
v
The environmental specifications listed in Table 24 on page 140
v
If the SAN768B will be installed in an EIA rack, ensure the following:
– All equipment installed in the rack has a reliable branch circuit ground
connection, and does not rely on a connection to a branch circuit, such as a
power strip.
– The rack is balanced and mechanically secured to provide stability in the
event of an earthquake.
– Additional equipment does not exceed the rack's weight limits.
Power specifications
DANGER
Multiple power cords. The product might be equipped with
multiple power cords. To remove all hazardous voltages,
disconnect all power cords. (L003)
The power subsystem is a red48 V dc power distribution system with a
provision for up to four 2000-watt, 48V dc bulk power supplies. Bulk power
supplies produce the intermediate distribution voltage in the distributed power
system.
The power specifications listed in Table 23 are calculated for fully-loaded systems
with four power supplies, eight FC8-48 port blades, two CP8 blades, two CR8
blades, and three blower assemblies. The use of application and/or encryption
blades will consume additional power.

Specification Value
Voltage Range: 85 - 264 VAC Auto-volt, Nominal:
100 to 240 VAC (auto-sensing)
Power supply output (each) Low line (85- 132 VAC), 1000W; High line
(180 - 264 VAC), 2000W
Input frequency Range: 47-63 Hz; Nominal: 50 - 60 Hz
AC inrush Maximum 20A peak
System power consumption AC power consumption is
configuration-specific. A system with four
FC8-48 port blades (loaded with 1W SFPs),
two CP8 blades, two CR8 blades, and two
blower assemblies consumes 1514 W.
