C-2 About PoE (Power over Ethernet)
Proprietary PD Detection
The
4H4285
‐
49
supports
a
subset
of
the
currently
deployed
proprietary
PoE
methods.
This
includes
support
for
Cisco
PDs,
including
a
proprietary
capacitor
based
detection
scheme.
Power Interface
The
4H4285
‐
49
can
interface
to
an
external
48 Vdc
supply
that
resides
in
a
Matrix
N5
chassis
or
from
a
separate
Matrix
N
Series
N
‐
POE
Power
System.
Matrix N5 Backplane 48 Vdc Interface
The
4H4285
‐
49
has
a
connector
that
interfaces
with
the
backplane
of
the
N5
chassis
for
48 Vdc
power.
This
power
connection
on
the
4H4285
‐
49
is
fused,
has
EMI
suppression
components
for
this
interface,
and
can
support
a
sustained
output
current
of
20 A.
Front Panel 48 Vdc Interface
The
48 Vdc
Optional
Power
Input
connector
on
the
4H4285
‐
49
front
panel
provides
a
power
interface
connection
for
an
Enterasys
Matrix
N
Series
N
‐
POE
Power
System,
which
provides
the
48 Vdc
power
and
return
as
well
as
the
power
supply
status
signals.
The
status
signals
indicate
the
presence
and
operating
state
of
each
power
supply
module
in
the
N
‐
POE
Power
System.
This
48 Vdc
Optional
Power
Input
interface
is
not
fused
as
the
N
‐
PoE
Power
System
has
a
circuit
breaker
for
each
PoE
switch
module
power
feed.
Warning:
The DFE module is shipped with a cover over its 48 Vdc Optional Power Input
connector. Do not remove this cover when the DFE module is installed in an N5 chassis.
This cover is removed only when you connect a 48 Vdc power cable from the Enterasys
N-POE Power System.
Advertencia:
El modulo DFE es embarcado con una cubierta sobre su conector de poder
opcional de 48 Vdc. No remover esta cubierta cuando el modulo DFE es instalado en un
chassis N5. Esta cubierta debe removerse unicamente cuando se conecta el cable de
poder de 48 Vdc hacia el Sistema de Enterasys de Energia por Cable (Enterasys N-POE
Power System).
Warnhinweis:
Im Auslieferungszustand der DFE Module stülpt eine Schutzkappe über
dem 48V Gleichspannungs-Anschluss, die nur dann abgezogen werden darf, wenn ein
Enterasys N-POE Power System angeschlossen wird. Keinesfalls darf diese Schutzkappe
abgezogen werden, wenn das DFE Modul in einem N5 Chassis installiert wird.
