1) The S7502E and the S7503E-S require not only an internal power module for its own power feed,
but also an appropriate external PoE power module, RPS500-A3 for example, to provide PoE
supply.
2) The S7503E, S7506E, S7506E-V, and S7510E require only internal PoE power modules,
PSR1400-D, PSR2800-ACV or PSR6000-ACV for example, for both their own power feed and PoE
supply to attached devices.
z
With PSR1400-D modules, an S7503E, S7506E, S7506E-V, or S7510E can provide a maximum of
6720 W of PoE supply.
z
With PSR2800-ACV modules, an S7503E, S7506E, S7506E-V, or S7510E can provide a
maximum of 1400 W of PoE supply.
z
With PSR6000-ACV modules, an S7503E, S7506E, S7506E-V, or S7510E can provide a
maximum of 5300 W of PoE supply.
In the case of PSR1400-D power modules, the power cables can be directly used as the PoE input
cables. For how to connect the power cables, refer to section “PSR1400-D power module” on page
3-10.
In the case of PSR2800-ACV or PSR6000-ACV power modules, you can connect the 16-A AC power
cables to the PoE input ends of the power modules for PoE input. For how to connect the power cables,
refer to section "PSR2800-ACV power module" on page 3-7 or "PSR6000-ACV power module" on page
3-7.
z
When you use PSR1400-D modules to provide PoE supply to attached devices and there are more
than three PoE-capable LPUs in the switch, you are recommended to use 1/0 AWG cables with a
cross section area of 53 mm
2
to ensure the steady and safe operation of the switch.
z
If customer-supplied PoE power cables are used as PoE power input cables for the S7502E and
the S7503E-S, you should ensure that the cables can bear a current of 50 A and have a minimum
cross section area of 8.4 mm
2
.
An external PoE power supply can be connected to the PoE input terminals on the rear panel of the
S7502E and the S7503E-S with dedicated PoE cables.
Figure 3-14 shows the rear panel of the S7502E and the S7503E-S.
