Switched Rack PDU

System requirements for outlet groups
To set up and use synchronized outlet control groups:
• You need a 10/100Base-T TCP/IP network, with an Ethernet hub or switch that has a
power source not shared by the computers or other devices being synchronized.
• If outlet groups are to be synchronized across multiple Switched Rack PDUs, those
Switched Rack PDUs must meet the following requirements:
– They must be on the same subnet.
– They must use firmware that has the same version number, which must be 3.3.1 or
higher for both the APC Operating System (AOS) module and the application
module.
• You need a computer that can initiate synchronized control operations through the
Web interface or control console of the Switched Rack PDUs or through SNMP.
• Outlet groups you synchronize must have the same Multicast IP address. Make sure
each Ethernet switch that connects Switched Rack PDUs allows Multicast network
traffic for that Multicast IP address.
