This data includes power and cooling requirements for the system cabinet only.
The VAX 6000 power system has the following modules:
• H405-E/F AC power controller
• H7206-B power and logic unit
• One H7214 DC power regulator
• One H7215 DC power regulator
• One H7242 DC power regulator
• Optional H7236-A battery backup unit
• Transformer (50 Hz systems only)
Most of the power modules are visible from the rear of the cabinet (see
Figure 1–5). For more information on these modules, refer to the VAX 6000
Platform Service Manual.
All systems have two unswitched IEC 320 receptacles located on the H405
AC power controller. The receptacles are fused at 10 amps for 60 Hz
systems and at 6 amps for 50 Hz systems. They are reserved for disk drives
or the H7236-A battery backup unit. All systems have one unswitched
IEC 320 receptacle fused at 2 amps, but it is not used in current VAX
6000 systems. For expander cabinet power requirements, see the VAXBI
Expander Cabinet Installation Guide.
