Labeling for Power Cables
On the PDU end
On the device end
If there are multiple power modules that are not
numbered in a device, number them in an
ascending order from the top down and from left
to right.
Only one power distribution unit (PDU) is
preinstalled in the All-in-One cabinet and
numbered PDU1.
More PDUs are numbered in an ascending
order from outside to inside and from left to
right.
The rack is divided into 42 U (1 U = 1.75 in.),
numbering from 1 to 42 from the bottom up.
For the network device occupying more than 1 U,
the label records the smallest height number. For
example, if a 2 U network device occupies 34 U
and 35 U, "34U" will be present in the label.
