4 Perform the following:
For 4x4 MIMO configurations and 2+2 Space Diversity configurations,
select Master or Slave in the Role field. This determines the role of
the IP-20C unit in the overall MIMO or Space Diversity configuration.
For MIMO 2x2 configurations and 1+0 Space Diversity configurations,
select Not-Relevant in the Role field.
5 Click Apply.

Resetting MIMO
In hardware failure scenarios, MIMO 4x4 provides a resiliency mechanism
that enables the link to continue functioning as a 2+0 XPIC link.
To restore full MIMO operation, the faulty equipment must be replaced. The
replacement equipment must be pre-configured to the same configuration as
the equipment being replaced. Once the new equipment has been properly
installed and, if necessary, powered up, you must reset MIMO.
Note:
MIMO reset causes a traffic interruption.
To reset MIMO:
1 Select Radio > Groups> MIMO. The MIMO page opens.
2 Select the MIMO group from the table.
3 Click Edit Group. The MIMO - Edit page opens.
