Chapter 1 Overview of the ZX4300PSwitch
The ZX4300P CompactPCI Ethernet 10/100 Mbps switch is the cost-effective and flexible
solution to Embedded Carrier Class Layer 2 switching requirements.
ZNYX Networks' ZX4300P is the first switch designed to support the upcoming PICMG 2.16
specification for a CompactPCI Packet Switching Backplane (CPSB), but it can also be deployed
in a standard CompactPCI chassis by using one of three optional Rear Transition Boards (RTB).
When installed in the fabric slot of a CPSB chassis, the ZX4300P includes support for the
extended CPSB specification, routing all 24 10/100 ports to the backplane. It also supports the
typical 19 node CPSB, and with the addition of the ZXRTB05 RTB, routes the remaining 5 ports
to rear panel RJ-45 connectors. This allows the systems architect to easily add another chassis to
the switched backplane fabric.
The same ZX4300P may be installed in a standard CompactPCI chassis and configured with rear
panel I/O for all 24 10/100 ports. In an extension of PICMG 2.16, ports 20 through 24 are routed
to the J4 connecter, which cannot be part of an H.110 connection. Options include either the
ZXRTB24 dual-slot RTB with 24 RJ-45 connectors or the ZX4024RP single slot RTB with two
RJ-21 Telco connectors.
In either chassis, the ZX4300P's Hot Swap and instant reconfiguration features allow rapid
installation in a live system and a mean time to repair of mere seconds.
By using the latest switch silicon, the ZX4300P features non-blocking line-rate switching, 802.3x
and back-pressure flow control. Like the ZNYX Networks OpenArchitect switches, the ZX4300P
is designed for NEBS compliance and may be used with any host operating system or any host
CPU including Sun SPARC, Intel x86, and Motorola PowerPC.
