Back Panel Connectors
There are multiple connectors on the ATCA-9305, reference Fig.2-2 for their location. The
back panel connectors, Zones 1 through 3, are described in this chapter. Whether individual
back panel connectors are populated on the ATCA-9305 depends on the specific product
configuration.

ZONE 1

Connector P10 provides the AdvancedTCA Zone 1 power (dual redundant -48 VDC) and sys-
tem management connections. Four levels of sequential mating provide proper functional-
ity during live insertion or extraction, see Tab le 8- 1.
