The standard 19-inch wide rack installation (feature code 0939) supports optional features that require
additional contiguous space:
• A second High Performance Flash Enclosure Gen2 pair (feature code 1605) requires an additional 4U
contiguous space.
• A 1U keyboard and display (feature code 1765) requires an additional 1U contiguous space. For
accessibility, the keyboard and display must be mounted at a height of 15 - 46 inches. If you add the
keyboard and display, ensure that you provide adequate space to accommodate them.
The DS8910F model 993 uses 16 and 32 Gbps Fibre Channel host adapters that run Fibre Channel
Protocol (FCP) or FICON protocol. The High Performance FICON (HPF) feature is also supported.
The DS8910F model 993 supports single-phase and three-phase power. The model 993 components all
have associated C13/C14 power cords for connection to iPDU features or to customer supplied rack
PDUs. If the location of the model 993 with relation to the rack C13 PDU receptacles requires 1 m jumper
C13/C14 power cables, they are also provided. These cords are used to attach to the model ZR1 or LR1
PDU receptacles available in the rack.
