Up to 6 composite asset sensors
are supported.
Tip: To increase the maximum number of composite asset sensors
attached to a Raritan PX2 PDU or EMX2-111, you can use Raritan's X
cable to enhance the power supply to the asset sensor chain. See
Using
an X Cable (on page 37).
Important: Do NOT mix different types of composite asset sensors in a
chain. For example, all in the chain are AMS-M2-Z or all are
AMS-M3-Z.
Using an X Cable
Raritan's EMX2-111 products support a maximum of four composite
asset sensors in a chain. For details, see
Daisy-Chain Limitations of
Composite Asset Sensors
(on page 36).
If you need to exceed the daisy-chain limitation, use Raritan's X cable to
connect composite asset sensors. This allows you to expand the
maximum number of composite asset sensors from four units per chain
to six units per chain.
An X cable is a combination of two male RJ-45 connectors, one
Raritan-defined male phone connector, and one female RJ-12 sensor
port.
The X cable supplies 12V voltage from the SENSOR port of the
EMX2-111 to the connected composite asset sensors.
Note: An X cable does not help enhance the power supply to asset
sensors connected to Raritan's EMX2-888, so do not use this cable with
them.
To connect composite asset sensors via an X cable:
1. Plug the male RJ-45 connector at the shorter end of the X cable into
the FEATURE port of the EMX device.
