Transition Networks SISPM1040-3xxx-L Web User Guide Parameter Descriptions: Reserved Power determined by : There are three modes for configuring how the ports/PDs may reserve power. Class: In this mode each port automatically determines how much power to reserve according to the class the connected PD belongs to and reserves the power accordingly. Four different port classes exist and one for 4, 7, 15.4 or 30 Watts. In this mode the Maximum Power fields have no effect. Allocation: In this mode you can allocate the amount of power that each port may reserve (default mode). The allocated/reserved power for each port/PD is specified in the Maximum Power fields. LLDP-MED: This mode is similar to the Class mode expect that each port determines the amount power it reserves by exchanging PoE information using the LLDP protocol and reserves power accordingly. If no LLDP information is available for a port, the port will reserve power using the class mode. In LLDP-MED mode the Maximum Power fields have no effect. For all modes: If a port uses more power than the Reserved Power for the port, the port is shut down. Power Management Mode : There are two modes for configuring when to shut down the ports: Actual Consumption: In this mode the ports are shut down when the actual power consumption for all ports exceeds the amount of power that the power supply can deliver or if the actual power consumption for a given port exceeds the reserved power for that port. The ports are shut down according to the port's priority. If two ports have the same priority the port with the highest port number is shut down. Reserved Power: In this mode the ports are shut down when total reserved powered exceeds the amount of power that the power supply can deliver. In this mode the port power is not turned on if the PD requests more power than available from the power supply. Capacitor Detection : Check the box to enable Capacitor Detection mode for legacy PoE device support. PoE Power Supply Configuration Primary Power Supply [W]: For being able to determine the amount of power the PD may use, it must be defined what amount of power a power source can deliver. Valid values are 1 to 370 Watts. PoE Port Configuration Port : This is the logical port number for this row. Ports that are not PoE-capable are grayed out and thus impossible to configure PoE for. PoE Mode: The PoE Mode represents the PoE operating mode for the port. Disabled: PoE disabled for the port. Enabled : Enables PoE IEEE 802.3at (Class 4 PDs limited to 30W). PoE Schedule : Scheduled by selecting PoE Scheduling Profile. Select Disabled or Profile 1 -16. Priority : The Priority represents the ports priority. The three levels of power priority are Low, High, and Critical. The priority is used when the remote devices require more power than the power supply can deliver. In this case the port with the lowest priority will be turned off starting from the port with the highest port number. Maximum Power : The Maximum Power value contains a numerical value that indicates the maximum power in watts that can be delivered to a remote device. The maximum allowed value is 30 W. 33763 Rev.

Parameter Descriptions
:
Reserved Power determined by
: There are three modes for configuring how the ports/PDs may reserve power.
Class
: In this mode each port automatically determines how much power to reserve according to the
class the connected PD belongs to and reserves the power accordingly. Four different port classes exist
and one for 4, 7, 15.4 or 30 Watts. In this mode the Maximum Power fields have no effect.
Allocation
: In this mode you can allocate the amount of power that each port may reserve (default
mode). The allocated/reserved power for each port/PD is specified in the Maximum Power fields.
LLDP-MED
: This mode is similar to the Class mode expect that each port determines the amount power it
reserves by exchanging PoE information using the LLDP protocol and reserves power accordingly. If no
LLDP information is available for a port, the port will reserve power using the class mode. In LLDP-MED
mode the Maximum Power fields have no effect.
For all modes
: If a port uses more power than the Reserved Power for the port, the port is shut down.
Power Management Mode
: There are two modes for configuring when to shut down the ports:
Actual Consumption
: In this mode the ports are shut down when the actual power consumption for all
ports exceeds the amount of power that the power supply can deliver or if the actual power consumption
for a given port exceeds the reserved power for that port. The ports are shut down according to the
port’s
priority. If two ports have the same priority the port with the highest port number is shut down.
Reserved Power
: In this mode the ports are shut down when total reserved powered exceeds the
amount of power that the power supply can deliver. In this mode the port power is not turned on if the
PD requests more power than available from the power supply.
Capacitor Detection
: Check the box to enable Capacitor Detection mode for legacy PoE device support.
PoE Power Supply Configuration
Primary Power Supply [W]
: For being able to determine the amount of power the PD may use, it must be defined
what amount of power a power source can deliver. Valid values are 1 to 370 Watts.
PoE Port Configuration
Port
: This is the logical port number for this row.
Ports that are not PoE-capable are grayed out and thus impossible to configure PoE for.
PoE Mode
: The PoE Mode represents the PoE operating mode for the port.
Disabled
: PoE disabled for the port.
Enabled
: Enables PoE IEEE 802.3at (Class 4 PDs limited to 30W).
PoE Schedule
: Scheduled by selecting PoE Scheduling Profile. Select Disabled or Profile 1 -16.
Priority
: The Priority represents the ports priority. The three levels of power priority are
Low
,
High
, and
Critical
. The priority is used when the remote devices require more power than the
power supply can deliver. In this case the port with the lowest priority will be turned off starting
from the port with the highest port number.
Maximum Power
: The Maximum Power value contains a numerical value that indicates the
maximum power in watts that can be delivered to a remote device. The maximum allowed value is 30 W.
