of Frame 4. FC 1951 can provide power for up to a total of three frames that are no
more than three frames away from the PDUs. In this example, Frame 1 is three
frames away from the PDUs in Frame 4.
The PDU requires two 200-250 vac power receptacles and a 30 amp circuit breaker.
In this example, the customer only needs to provide two 30 amp rated outlets (one
for each PDU in the FC 1951) to power the entire library. The specific type of outlet
that is required is determined by the specific power cord feature (FC 9954 through
9959, and 9966) that was ordered with the FC 1951 (See 3 , and 4 in Figure 24).
The FC1951 includes two internal power cords that power the frame where the
PDUs are installed (Frame 4). The customer must order FC9989 (two 4.3-m power
cords) for each powered frame that attaches to the PDUs. In this example, FC9989
would be ordered for Frame1, and Frame 5.
The fiber channel switches that are installed (In this example, Frame 5) plug
directly into the PDU in the adjacent frame. Two of the power supply cables from
the switches 1 plug into one PDU, and the other power cables 2 plug into the
other PDU for redundancy. With this example of the switches plugged directly into
the PDUs, the switches and PDUs must be in adjacent frames. For configurations
that require the switches and PDUs to be 2 or 3 frames away from each other, the
bifurcated power cords extensions must be used.
Referring to 4 , the customer must specify the feature codes for the proper power
cord type for their geographic location. The power cord feature codes that are used
with FC1951 are FC9954 through 9959, and 9966.
