HP ProLiant SL2500 Scalable System - Manual (Page 52)

Power capping 52
To turn an SL server node on or off, use the SET POWER command:
SET POWER {ON|OFF|ENABLE|DISABLE} {ALL | <PORT#> <DMPORT#> {<NODE#>|ALL}}
where:
ALL is used when the command applies to all nodes. You can also use ALL when the command applies to
all the server nodes in a particular SL server enclosure.
<PORT#> refers to the HP APM, PDM1, or PDM2 port numbers.
<DMPORT#> refers to the HP APM Distribution Module port number or the HP Intelligent Modular PDU
Extension Bar outlet number.
<NODE#> refers to the SL server node.
For example, to power on SL server node 3, enter:
SET POWER ON 2 4 3
To power off SL server node 3, enter:
SET POWER DISABLE 2 4 3
When you power on a particular SL server enclosure, you must include either the node number or ALL in the
command.
To power on the SL server nodes in the enclosure, enter:
SET POWER ON 2 4 ALL
To power on all nodes connecting to the chassis on all HP APM Distribution Module ports, enter:
SET POWER ON ALL
SNMP traps denoted by an asterisk (*) are not supported on the HP ProLiant s6500 Chassis. The SET POWER
ON ALL and SET POWER OFF ALL commands are not supported on HP APM 1.54 on the HP Moonshot
1500 Chassis.
To power on the PDU ports, enter:
SET POWER ON PDM
To power off PDU ports, enter:
SET POWER OFF PDM
Polling servers for power values
To enable a background process that polls each server for its average, minimum, and maximum power
values, enter ENABLE POLLPOWER.
Polling these values increases the performance of SNMP queries of these power values.
The poll cycle time varies depending on how many server chassis are plugged into the HP APM system. The
more chassis that are present, the less frequently each server will be polled.
If POLLPOWER is enabled, then an SNMP request for any of these values on any resident server returns the
last polled value instead of requesting the real time values from the server at the time the request is made.
