Step 10—Expansion—System Cabinet and I/O Expansion Cabinet
Step 10a—System Cabinet
System Cabinet includes one three-phase power regulator with space for two additional three-phase power regulators. System cabinets shipped after June 1996 (H9F00-FC/FD/FE Rev B03 or greater) include the H7263-AC/AD non-battery back-up ready power regulator. See Step 11 for power expansion options for these system cabinets.
Maximum four I/O channels per cabinet allowed. PCI and XMI plug-in units each require one I/O channel connection. Four lower expansion bays are available for plug-in units. The lower bays accommodate plug-in units as follows.

Expansion Bay | | Plug-In Unit | | |
Location | | (PIU) | Quantity | Expansion Bays Occupied |
| | | | |
Lower | Disk plug-in unit | (BA660-AB) | Four maximum | Front or Rear |
Lower | XMI plug-in unit | (DWLMA-AA) | Two maximum | Front and Rear |
Lower | Battery plug-in unit(H7237-AA/AC/CA/CB) | One maximum | Front and Rear |
Lower | PCI plug-in unit | (DWLPB-AA) | Two maximum | Rear only |
Step 10b—I/O Expansion Cabinet
I/O Expansion Cabinet includes one three-phase power regulator - Provides space for two additional three-phase power regulators
H9F00-BA/BB/BC Rev D03 or later cabinets include the H7263-AC or H7263-AD non-BBU capable power regulator. Refer to Step 11 for expansion options.
H9F00-BA/BB/BCI/O expansion cabinetThree phase power, maximum two per system. Note: -BA = 60 Hz, 208V, -BB = 50 Hz, 380/416V, -BC = 50/60 Hz, 202V.
Expansion cabinet can be configured to hold all disk plug-in units or combination of disk plug-in units and PCI or XMI plug-in units.
-Six expansion bays—two upper and four lower—are available for plug-in units. The two upper bays accommodate maximum of two disk plug-in units. The four lower bays accommodate plug-in units as follows:
Expansion Bay | | Plug-In Unit | | |
Location | | (PIU) | Quantity | Expansion Bays Occupied |
Upper | Disk plug-in unit | (BA660-AB) | Two maximum | Front or Rear |
Lower | Disk plug-in unit | (BA660-AB) | Four maximum | Front or Rear |
Lower | PCI plug-in unit | (DWLPB-AB) | Two maximum | Rear only |
Lower | XMI plug-in unit | (DWLMA-BA) | Two maximum | Front and Rear |
Lower | Battery plug-in unit (H7237-AA/AC/CA/CB) | One maximum | Front and Rear |
Step 11 Power Expansion Components
System Cabinet and Expansion Cabinets must be same type; either three-phase or single-phase. Mixing of three-phase and single-phase cabinets in same system configuration is not allowed.
Determine the need for adding second power regulator by filling in the EPU- Power Configuration Table. Note: The Power Configuration Table provides a manual method for determining the need of second power regulator. Equivalent power unit (EPU) is an equivalent value of power used (48 VDC) by each option.
