2. (Optional) Attach the MPUIQ-SRL module to an RJ-45 to 9-pin female adaptor. Attach the
adaptor to the serial port of the serial device.
3. Plug one end of a CAT 5 cable (4-pair, up to 150 ft/45 m) into an available numbered port
on the rear of the MergePoint Unity switch. Plug the other end into the RJ-45 connector of
the MPUIQ-SRL module.
4. Connect the power supply to the power connector on your MPUIQ-SRL module. The cable
expander can be used to provide power for up to four MPUIQ-SRL modules from a single
power supply.
5. (Optional) Attach a USB-to-barrel power cord to the power connector on your MPUIQ-SRL
module. Plug the USB connector on the USB-to-barrel power cord into any available USB
port on the serial target device.
NOTE: You can not use the cable expander with the USB-to-barrel power cord. Multiple MPUIQ modules can use
power off of the power supply, but not off of the target device.
6. If using the power supply, connect the MPUIQ-SRL module power supply to an
appropriate AC wall outlet. Turn on your serial device.
Cascading MergePoint Unity Switches
You can cascade up to two levels of MergePoint Unity switches, enabling users to connect to
up to 1024 servers. In a cascaded system, each target port on the main MergePoint Unity switch
will connect to the ACI port on each cascaded MergePoint Unity switch. Each cascaded switch
can then be connected to a server with an IQ module.
To cascade multiple MergePoint Unity switches:
1. Attach one end of a CAT 5 cable to a target port on the MergePoint Unity switch.
2. Connect the other end of the CAT 5 cable to the ACI port on the back of your cascaded
MergePoint Unity switch.
3. Connect the devices to your cascaded MergePoint Unity switch.
4. Repeat these steps for all the cascaded MergePoint Unity switches you wish to attach to
your system.
NOTE: The system will automatically “merge” the two switches. All servers connected to the cascaded MergePoint
Unity switch will display on the main MergePoint Unity switch server list in the local UI.
NOTE: The MergePoint Unity switch supports one cascaded switch per target port of the main switch. You cannot
attach more switches to the cascaded switches.
NOTE: Local port cascading is not supported on the MergePoint Unity switch.
