Replacing a Backplane
The Avaya M770 has two backplanes. The lower backplane serves the X-switch and
Avaya M440 Gate Switch modules, while the upper backplane connects the
Avaya M770 ATM modules. Each backplane is sent with a detailed Installation
Guide. The location of each backplane in the hub is shown in Figure 4.2 below.
