Quidway S5300 Series Ethernet Switches
Quick Start
l
PGND and BGND are two copper bars, on which the terminal blocks are short-circuited,
therefore which terminal is connected makes no difference. It is only necessary to give the row
and column of the power distribution box, instead of giving the specific serial number of the
terminal block on the copper bar. For example, if the label on the loaded cabinet side is "A01-
BGND", it means that the power cable is a BGND that connects BGND copper bar in the power
distribution box on Row A, Column 01 in the machine room. Information on the labels for PGND
cables should be given in a similar way.
B.6.2 Engineering Labels for AC Power Cables
The labels are affixed to both ends of an AC power cable that provides AC power supply to
cabinets, including 220 V, PGND, and BGND cables. The 220 V AC cables and related PGND
and BGND cables are covered with insulating sheath, so the labels need to contain only the
words of "AC" and the cabinet numbers.
The labels for AC power cables are affixed to one side of the identification plates on cable ties.

The label only carries location information about the opposite equipment and the power socket,
while information about the local end is not necessary.
Make sure that labels are affixed in correct direction. That is, after the cable ties are bundled
onto the cable, the identification plates with the labels should face up, and the text on the labels
in the same cabinet should be in the same direction, as shown in
Issue 01 (2008-12-26)
On the distribution box side, the label "B03--48V2" indicates that the cable is -48 V DC
supply, connected to DC power socket 2 on row B, column 03 in the equipment room.
NOTE
In the power distribution box or the first power cabinet of a row in a transmission equipment room, every
terminal block on the -48 V connector bar has a numeric identification. For example, in the above label of
"A01/B08--48V2", "08" (or sometimes "8") is the numeric identification of the terminal block.
Table B-9.
Meaning
MN: serial number of the cabinet or the socket where the power is led in
B: chassis number, numbered in the bottom-top order with two digits, for
example, 01.
n: power port number, numbered as 1 to 3 in bottom-top and left-right
order.
Serial number of the socket where the power is led in: the location of the
socket is marked out according to the actual situation. If the sockets can
be identified by row numbers and column numbers, they can be numbered
following the same rule for the cabinets. If the sockets cannot be identified
by rows and columns, specify the detailed locations to avoid confusing
with other sockets.
