This packet-switched platform features a PICMG® 2.16-compatible midplane
supporting a Redundant Host architecture for I/O-intensive applications. Part of
the Advanced Managed Platform offering, it provides OEM equipment designers with
a carrier-grade, standards-based, high availability computing platform for
demanding mission-critical applications.
The ZT 5085e CompactPCI® platform supports five-nines (99.999%)
availability with built-in redundancy for active system components including
system master CPU boards, Ethernet switches, intelligent shelf managers (ISMs),
power supplies and fan trays. Redundant ISMs enable customers to manage multiple
Intelligent Platform Management Interface (IPMI)-based components in the
platform and conduct comprehensive 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 5085e platform is part of our IPnexus™ family of embedded packet products and is also designed to interoperate with any third-party PICMG 2.16-compatible boards.
The ZT 5085e 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 5524e Single Board Computer with the ZT 4901e I/O Mezzanine Expansion Card option allows bridging from one PCI segment to the other.
The ZT 5085e also supports a Redundant Host architecture, providing fault tolerance at the system master level. Two system masters can control the 12 peripheral slots on PCI segments one and two in both active/active and active/standby modes. For this configuration, two pairs of ZT 5524e/ZT 4901e boards are required (the first mated pair fits in slots 9-10 and the second fits slots 11-12, see Figure 1).
Figure 1: Component layout for ZT 5085e platform
In both these configurations, the 12 peripheral slots support one single H.110 bus spanning slots three through eight and 13 through 18. 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.
The ZT 5085e includes two redundant IPnexus CPC7301 Intelligent Shelf Managers (ISMs) operating in active/standby mode. The CPC7301 is the central management component for all Performance Technologies PICMG 2.16-compliant platforms. It uses standards-based interfaces, allowing management of third-party IPMI-based products within an IPnexus platform. It communicates with components in the ZT 5085e via point-to-point IPMB busses in a unique star topology to achieve comprehensive, highly available management.
The ZT 5085e 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.

With 250W power supplies, the ZT 5085e platform supports more than 40W per slot or when scaled to 325W DC 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).
