Warning:
The ZT 5085 is configured for either AC or DC input. The system’s power input configuration (AC
or DC) must match the power supply input voltage (AC or DC). DO NOT INSTALL A DC INPUT
POWER SUPPLY IN A ZT 5085 CONFIGURED FOR AC INPUT.
A.3.1
Universal Midplane
The ZT 5085 incorporates a universal midplane that can be jumpered to provide either 5 V or 3.3
V V(I/O) to the CompactPCI slots. See
Section 2.4.3, “Setting V(I/O)” on page 29
for information
on changing V(I/O).
A.3.2
Midplane Connectors and Devices
The ZT 5085 includes a hot swap-compatible 21-slot backplane configured with a packet switched
bus and two CompactPCI buses.Refer to the
Figure 29, “ZT 5085 Backplane Connector Locations
Figure 30, “ZT 5085 Backplane Connector Locations (Rear)” on page 66
for connector locations.
