The IPnexus™ ZT 5088e 12U General Purpose Packet-Switched Platform is an extremely flexible, high availability platform, configurable for both compute-intensive and 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 5088e platform supports five-nines (99.999%) availability with built-in redundancy for active system components including Ethernet switches, intelligent shelf managers (ISMs), power supplies and fan trays. Redundant ISMs 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 setup, maintenance and repair and minimizing the thermal challenges of traditional cabling methods.
The midplane is flexible and can accommodate multiple configurations. It supports up to 18 independent servers communicating over the PICMG 2.16-compliant Ethernet midplane (slots 3-20) or four dedicated system masters supporting four independent PCI bus segments (see Figure 1).
Figure 1: Component layout for the ZT 5088e platform
The ZT 5088e can also be configured to support two extended bus segments. PCI segments one and two are bridged together using the ZT 5524e System Master Processor Board and ZT 4901e I/O mezzanine expansion by bridging segments one and two together, one system master can control seven peripheral slots at 66MHz bus speed. The same bridging can be performed on PCI segments three and four with the ZT 5524e/ZT 4901e pair installed in slots 16 and 17. 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 5088e 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 5088e via point-to-point IPMB busses in a unique star topology to achieve comprehensive, highly available management.
The ZT 5088e platform supports a redundant, scalable power solution, accommodating up to eight 3U CompactPCI power supplies, divided into two separate power subsystems. Each delivers power to one of the two power domains on the midplane. Each power subsystem supports N+N redundant power supplies and receives input power from redundant DC or AC inputs.
This is critical in central office locations where two power plants deliver redundant DC input into high-availability devices. These two power subsystems maintain isolation of these inputs (no diode OR’ing) to ensure that failure of one will not affect the power input of the other. For high availability and to isolate catastrophic events, the midplane is divided into two separate power domains. Each power domain supports one fabric slot and nine node slots. The redundant ISMs and fan trays draw power from both domains for continued operation, should one domain fail (see Figure 2).

With 250W power supplies, the ZT 5088e platform supports more than 40W per slot or, when scaled to 334W 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).
