ZT 5085
12U Redundant Host Packet Switched Platform
Intel in
Communications
Product Overview
This packet switched platform features a
PICMG* 2.16-compatible midplane supporting
redundant-host architecture for I/O-intensive
applications. It is one of several modular
telecom building blocks from Intel, providing
OEM equipment designers with a carrier-grade,
standards-based, high-availability computing
platform for demanding mission-critical
applications.
The ZT 5085 CompactPCI* platform supports
five-nines (99.999%) availability with built-in
redundancy for active system components
including system master CPU boards, Ethernet
switches, chassis management modules, power
supplies and fan trays. Redundant chassis
management modules enable customers to
manage multiple SBCs and conduct chassis
diagnostics remotely for enhanced system
reliability. Ethernet signals are routed across the
midplane without the use of cables, saving time
in set-up, maintenance and repair, and
minimizing the thermal challenges of traditional
cabling methods.
The ZT 5085 platform is designed to
interoperate with all members of the Intel
NetStructure
TM
family of packet switched
products, and with third-party boards meeting
the PICMG 2.16 specifications.

ZT 5085
Midplane Configuration and Details
The ZT 5085 platform is flexible and can accommodate
multiple configurations. It can be configured as two
independent PCI bus segments, each with up to two
dedicated system masters. Use of the ZT 5524 System
Master Processor Board with the ZT 4901A I/O
Mezzanine Expansion Card allows bridging from one
PCI segment to the other.
The ZT 5085 also supports redundant-host architecture,
providing fault tolerance at the system master level. Two
system masters can control the twelve peripheral slots
on PCI segments one and two in both active/active and
active/standby modes. For this configuration, two pairs
of ZT 5524/ZT 4901A boards are required (the first
mated pair fits in slots 9-10 and the second fits slots
11-12, see Figure 1).
In both these configurations the 12 peripheral slots
support one single H.110 bus spanning slots three
through eight and thirteen through eighteen.
All slots support IEEE 1101.11-style, 80mm-deep
transition cards in the rear-panel I/O section directly
behind the midplane. Each node and fabric slot may be
independently configured for 3.3V or 5V VI/O operation.
Chassis Management Module
The ZT 5085 includes two redundant Intel
NetStructure
TM
ZT 7102 chassis management modules
(CMMs) operating in active/standby mode. The ZT
7102 is the central management component for all
Intel
NetStructure
TM
PICMG 2.16-compliant platforms.
It uses standards-based interfaces, allowing
management of third-party IPMI-based products within
a NetStructure platform. It communicates with
components in the ZT 5085 via point-to-point IPMB
busses in a unique star topology to achieve
comprehensive, highly available management.
Redundant Power Subsystems
The ZT 5085 supports an N+N redundant, scalable
power solution with up to eight standard 3U x 8HP
power supplies. The power supplies are divided into
two separate power subsystems, each housing four
power supplies and receiving input power from
redundant DC or AC inputs. This is critical in central
office locations where two independent power feeds
deliver redundant DC input into high-availability
systems. The two power subsystems maintain isolation
of these inputs (no diode OR'ing), and provide
protection so that failure of one power input will not
affect the other.
Cooling Architecture
With 250W power supplies, the ZT 5085 platform
supports more than 40W per slot or, when scaled to
350W power supplies, powers and cools up to 50W
per node slot and 80W per fabric slot. The platform
houses three hot-swappable fan trays, serviceable from
the front. Each tray includes three blowers, and spans
the distance from front to back of the chassis. The
front blower cools the front card cage area, and the
rear blower cools the power supplies and rear of the
card cage. The middle blower cools both areas,
providing N+1 redundant cooling for the entire chassis
(see Figure 3).
