Switched Rack PDU

Configure and Control Outlet Groups
Outlet group terminology
An outlet group consists of outlets that are logically linked together on the same
Switched Rack PDU. Outlets that are in an outlet group turn on, turn off, and reboot in a
synchronized manner:
•A local outlet group consists of two or more outlets on a Switched Rack PDU. Only
the outlets in that group are synchronized.
•A global outlet group consists of one or more outlets on a Switched Rack PDU.
One outlet is configured as a global outlet, which logically links the outlet group to
outlet groups on up to three other Switched Rack PDUs. All outlets in the linked
global outlet groups are synchronized.
– For global outlet groups, the initiator outlet group is the group that issued the
action.
– For global outlet groups, a follower outlet group is any other outlet group that is
synchronized with the initiator outlet group.
When you apply an outlet control action to outlets that are members of an outlet group,
the outlets are synchronized as follows:
• For a global outlet group, use the delay periods and reboot duration configured for
the global outlet of the initiator outlet group.
• For a local outlet group, the outlets use the delay periods and reboot duration of the
lowest-numbered outlet in the group.
