Technical Advisory Bulletin:
TrangoLINK® Giga IDU rev A with square white power connector
TrangoLINK® Apex & ApexPlus using direct power
Using Giga IDU with redundant power supply/sources
When using two power supplies to power one or more units, one power supply may sense the power from the other and not provide power until the primary source is lost which could cause a reboot on the connected equipment.
Does not affect GigaPlus or GigaPro product lines or. Apex series using POE.
Diodes must be installed on the -48 power supply lines between the IDU/Apex and power supply to prevent voltage from back feeding the power supply. See diagram below for additional info.
See diagram attached.
