Configuring The Total Power Available To A Slot; Setting Port Priority Levels - Alcatel-Lucent OmniSwitch 6465 Hardware User's Manual

Managing Power over Ethernet (PoE)

Configuring the Total Power Available to a slot

Like the maximum port power allowance, the system software also provides a maximum slot-wide power
allowance. By default, each slot is authorized by the system software to use a number of watts to power all
devices connected to its ports depending on which power supply is used.
As with the maximum port power allowance, the user can either increase or decrease this value based on
the allowed ranges.
Important. Decreasing the slot-wide power could cause lower priority ports to lose power if the new
value is less than the total PoE power currently being consumed.
To increase or decrease the total power available to a slot, use the
Since you are setting the power allowance for an individual slot, you must specify a chassis/slot value in
the command line. For example, the syntax
-> lanpower slot 1/1 maxpower 400
reduces the power allowance of the slot to 400 watts. This value is now the maximum amount of power
the slot can use to power all attached devices (until the value is modified by the user).
Note. Changing the maximum power available to a slot or port does not reserve or immediately allocate
that power. These settings are only used for configuring a maximum amount of power that may be used,
any unused power is still available and remains a part of the overall PoE budget.

Setting Port Priority Levels

As not all Powered Devices (PDs) connected to the switch have the same priority within a network setting,
the OmniSwitch allows the administrator to specify priority levels on a port-by-port basis. Priority levels
include low, high, and critical. The default priority level for a port is low.
Low. This default value is used for port(s) that have low-priority devices attached. In the event of a
•
power management issue, inline power to low-priority is interrupted first (i.e., before critical and high-
priority).
High. This value is used for port(s) that have important, but not mission-critical, devices attached. If
•
other ports in the chassis have been configured as critical, inline power to high-priority is given second
priority.
Critical. This value is used for port(s) that have mission-critical devices attached, and therefore require
•
top (i.e., critical) priority. In the event of a power management issue, inline power to critical is main-
tained as long as possible.
To change the priority level for a particular port, use the
allows you to set priority levels on a port-by-port basis, be sure to specify chassis/slot/port information in
the command line. For example, the syntax
-> lanpower port 1/1/4 priority critical
changes the priority value of the port to the highest priority level of critical. Now that the default value has
been reconfigured, this port should be reserved for those PDs that are mission critical for network opera-
tions.
