Installation Manual
H3C S7500 Series Ethernet Switches
Note:
In the figure: (1) indicates a dummy panel; (2) indicates a cabling frame; (3)
indicates a nonstandard mini panel
Small squares in the figure indicate guide rails.
A1 through H1 and A2 through H2 are guide rails at the corresponding positions.
M1 through M13 indicate dummy panels at the corresponding positions in the
standard configuration.
In a DC cabinet, you may need to remove the M13 in the upper most, and move the
DC power distribution component which originally locates at the rear of the cabinet
to this position.
In AC cabinets, M13 does not exist, and the position is for the AC power distribution
component.
The S7500 series and other devices that comply with the N68 cabinet size can be
installed in the cabinet.
You need not to use the cabinet exactly as the figure shows, but can adjust the
position of guild rails and dummy panels as needed.
The dummy panels are for comeliness purpose only, so that you need not to install
them when they are in shortage.
The power of your device should be within the range allowed by the air breaker.
Refer to power distribution part for details.
The squares with shadow marks in the figure represent the four-hole guide rails,
which can bear a weight of 90 KG; and the squares without shadow marks represent
the two-hole guide rails, which can bear a weight of 40 KG.
