HPMM Redundancy Display Sequences

Each redundant HPMM partner conforms to the Startup sequences as described earlier in this section. In
addition, upon receiving a Swap command, the primary HPMM temporarily displays the SWAP text
while transitioning to a secondary status. However, there is no visible delay while the secondary HPMM
transitions to a primary status. An example of the this sequence is given in the table below.
SWAP sequence (Detailed Display mode)
An example of a display sequence during the HPMM swapping process with the Detailed Display mode
enabled is listed in the following figure for HPMM 1 and HPMM 2.
