7-6 Configuring System Power and PoE
Stackable B5 and C5 Devices
Procedure 7-2 PoE Configuration for Stackable B5 and C5 Devices
Step Task Command(s)
1. Configure PoE parameters on ports to which
PDs are attached.
• admin — Enables (auto) or disables (off)
PoE on a port. The default setting is auto.
• priority — Sets which ports continue to
receive power in a low power situation. If all
ports have the same priority and the system
has to cut power to the PDs, the PDs
attached to the lowest numbered ports have
the highest priority for receiving power. The
default setting is low.
• type — Associates an alias with a PD, such
as “siemens phone.”
set port inlinepower port-string {[admin {off |
auto}] [priority {critical | high | low}] [type
type]}
2. (Optional) Enable SNMP trap messages on the
device. The default setting is enabled.
set inlinepower trap {disable | enable} unit-
number
3. (Optional) Set the PoE usage threshold on the
device. Valid values are 11–100 percent. The
default setting is 80 percent.
set inlinepower threshold usage-threshold
unit-number
4. (Optional) Specify the method the Enterasys
device uses to detect connected PDs.
• auto (default) — The Enterasys device first
uses the IEEE 802.3af/st standards resistor-
based detection method. If that fails, the
device uses the proprietary capacitor-based
detection method.
• ieee — The Enterasys device uses only the
IEEE 802.3af/at standards resistor-based
detection method.
set inlinepower detectionmode {auto | ieee}
5. (Optional) Set the PoE management mode on a
specified module.
• realtime (default) — Manages power based
on the actual power consumption of the ports.
• class — Manages power based on the IEEE
802.3af/at definition of the class upper limit
for each attached PD, except classes 0 and
4, for which the actual power consumption is
used. In this mode, the maximum amount of
power required by a PD in the advertised
class is reserved for the port, regardless of
the actual amount of power being used by the
device.

class} module-number
