Chapter 2
NOTE The extension PDU (E7670A) only increases the number of
available receptacles. The total current carrying capacity still is
limited to 16 amps for the two PDUs, when daisy chained. In
addition, the extension PDU is limited to carrying only 10
amps.
Placement of PDU
To determine where the PDU mounts, eliminate positions directly behind
equipment listed in Table 2-3. (PDUs conflict with these units when mounted in
the same space). Then decide the most convenient location. The PDU can be
mounted vertically using the non-EIA mounting holes on the outer edges of the
vertical columns. Or it can be mounted horizontally between the columns.
When monitor and UPS units are present, the PDU can be horizontally mounted
across the rack opening, behind one of these units. However, PDUs can also be
mounted vertically on the opposite side of the rack from the door hinges.
Table 2-3. PDU Placement is Not Recommended behind These Units
