Facility requirements
The facility where the DC Director is in use must meet the following requirements to provide for correct
operation:
• Adequate supply circuit, line fusing, and wire size, as specified by the electrical rating on the chassis
nameplate
• An air flow of at least 350 cubic feet per minute (595 cubic meters per hour) in the immediate vicinity
of the DC Director
• The power specifications listed in Table 23
• The environmental specifications listed in Table 24
• Electrical interference less than the levels stated in the standards listed in Table 27 .
• If the DC Director 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
The power subsystem is a red48V DC power distribution system with a provision for up to four
1000-watt, 48V DC bulk power supplies. Four bulk power supplies produce the intermediate distribution
voltage in the distributed power system.
The power specifications in
Table 23 are calculated for fully loaded systems with four power supplies. A
fully loaded system has eight FC8-48 port blades, two CP8 blades, two CR8 blades, and three blower
assemblies.
