Program the result into the chassis.

Repeat steps 2-3 for each eligible chassis.

To remove a power cap, use SET POWER CAP NONE. This action removes all power cap settings from all

the servers.

Creating SL-APM power mappings

Zones are collections of SL-APM enclosures that can be given a unique name that can be referred to for

power capping purposes.
Zones provide the SL-APM user with the capability of distinguishing groups of enclosures as targets for power

or management operations. When zones are defined they are strictly a boundary definition that is kept
within the SL-APM for its purposes. Zones can be added or removed with the ADD ZONE and REMOVE ZONE

commands.
When the first ADD references a zone name that does not exist, the zone is automatically created and the
indicated ports are populated into the newly created zone. Subsequent ADD ZONE commands that reference

the same zone name causes the specified ports to be added to the existing zone. No limit exists for the

number of ports other than the maximum SL-APM supports in hardware that can be added to a zone. Multiple
port listings can be used with a single ADD ZONE command, or multiple ADD ZONE commands can be used

with each command adding new ports to the zone previously defined by the first ADD ZONE command.
To remove zone references to ports, use the REMOVE ZONE command. When the last port is removed from

a zone, the zone is automatically deleted. A zone cannot exist where no ports are assigned to it and zone

port definitions cannot overlap (that is, the same SL chassis cannot exist in more than one zone).
Defining zones is an optional function, and is useful for applying power caps to some chassis while excluding
others or applying different power caps to different groups or single SL chassis.
Since SL-APM zones are merely definitions of user defined SL-APM group boundaries (and by extension any

chassis that are plugged into those ports), they ignore the actual physical presence of enclosures as they are

being defined in the SL-APM CLI. Empty SL-APM ports can be included in a zone. If an enclosure is plugged
into that port sometime later, it automatically is part of that zone. A reminder message will be printed if a

zone is mapped to a SL-APM port that currently has no SL enclosure plugged into it.
After zone mappings have been completed with the ADD ZONE and REMOVE ZONE commands, the SHOW

ZONES command can be used, for example:
> show zones
Zone RED:

Power Manager port 1:

Dist. Module port 1

Zone BLUE:

Power Manager port 1:

Dist. Module port 2

Dist. Module port 3

Zone GREEN:

Power Manager port 2:

all Dist. Module ports included

Zone YELLOW:

Power Manager port 3:

Dist. Module port 1
