Protected Paths Overview
When adding an HO33120 or HO33300 output board to the Trinix router
used in a Protected Path, the following should be observed:
•
Add the board during a non-critical time as it may take up to four
seconds to recognize the board. A two-minute delay can cause signal
disruption on the active board’s outputs.
•
Telnet into the control system and turn off the refresh feature; wait 30
seconds before turning on the refresh feature once the output board is
powered up.
How the refresh feature is turned off depends on the installed control
system.
