3. Applying Power
Power Connection Descriptions
Each of the three switch models has different procedures for applying power.
SESPM1040-541-LT-AC-xx : AC-powered power source (PSE) provides up to 90 Watts on
individual ports (specific port configuration may apply), not to exceed 180 Watts total.
Power to the SESPM1040-541-LT-AC-xx is via a built-in 12-foot 16 AWG power cable
with a country specific plug. The -AC option is powered by an internal power supply
(120-240VAC, 47-63Hz). The AC input is via a hardwired AC cord or hardwired into AC
mains via customer supplied conduit and conduit connectors.
SESPM1040-541-LT-DC : a DC-powered power source (PSE) provides up to 90 Watts on individual ports (specific
port configuration may apply) (not to exceed 240 Watts total). Power to the SESPM1040-541-LT-DC is from an
external source with an input range of 40-57VDC (48VDC nominal) to a 2-pin terminal block (can accept up to
12AWG wire).
SESPM1040-541-LT-PD : a PoE-powered device (PD) receiving power over Ethernet or over parallel fiber and
copper cable and providing up to 80W of total PoE power. The -PD version includes a 12V Aux port which can be
used to provide auxiliary power to a PC, lighting or other accessories. PoE power to the SESPM1040-541-LT-PD is
via an external PSE that can classify with IEEE 802.3bt Type 4 Class 8 devices such as the SESPM1040-541-LT-AC
and -DC. The -PD can also be powered by a standalone DC power supply. The -PD version features an optional
Aux port for spitting some of the incoming PD power out to an isolated 12VDC power port.
Auxiliary 12V power port
: 2-position bare wire terminal block with screw retention up to 12AWG wire size.
Note : Constant power must be provided for the real time clock; the switch has a super Cap that provides backup
to the real time clock for up to 12 hours. Beyond that, battery backup must be provided externally through a
UPS.
Last Gasp
In the event of power failure, the switch will send an SNMP trap notification of the power failure. The
notification will only be sent on switch port 5. The 'Last Gasp' feature provides 10W for 5mS; however, POE
power is not protected on failure.
AC Power Cords
Due to the integrated power supply, the AC power cord comes installed in the switch from the factory.
The following versions are available, and the product should be ordered with the appropriate suffix to ensure
the correct country/region cord is installed. The –AC version has these AC power cords available:
