Chapter 4

Replacing Components

The power supply units, supervisor modules, fans and backplanes are field replaceable. All those components except the backplanes are hot-swappable, so that the hub can remain operational while you are replacing them. You will need to disassemble the Avaya M770 completely to replace the backplanes.
