Procedure 7-3 PoE Configuration for G-Series Devices (continued)
Step
Task
7.
(Optional) Configure the allocation mode for
system power available for PoE.
• auto (default) — Available power is
distributed evenly to PoE modules based on
PoE port count. A change in available power,
due to a change in power supply status or
redundancy mode or to the addition or
removal of modules, triggers an automatic
redistribution of power to the PoE controller
on each PoE-capable module.
• manual — The power budget for each PoE
module is configured manually, using the set
inlinepower assign command.
The configured wattage assignments are
used to calculate each module's percentage
of total available power. If the total available
PoE power changes, a redistribution of
available power occurs, applying the
calculated percentages.
In manual mode, power recalculations do not
occur under the following circumstances:
• A PoE module is added. The new module has
a power budget of zero until it is manually
provisioned. Since the sum of the manually
provisioned wattages cannot exceed the total
system power available, you may have to
adjust existing budgets to free up power for
the new module.
• A PoE module is removed. In this case, the
assumption is that the removed module will
be replaced with a new module that should
receive the same amount of PoE power.
8.
(Only if the set inlinepower mode command is
set to manual) Assign specific wattage to a PoE
module.
If the set inlinepower mode command is set to
manual, you must assign power to each PoE
module; otherwise, the module ports will not
receive power.
The sum of the wattage configured for each
module cannot exceed the total power available
for PoE on the Enterasys device.
If a G-Series device is configured for non-
redundant mode (set system power) and
manual mode (set inlinepower mode) and a
power supply fails, the G-Series device
redistributes the remaining power to the
modules. When power is restored on the failed
power supply, however, you must manually
reconfigure the power for each module.
Use the clear command to clear the power value
manually assigned to one or more modules.
Command(s)
set inlinepower mode {auto | manual}
set inlinepower assign watts module-number
clear inlinepower assigned [module-number]
