About this Document

This document is the main user guide of the WR-Z16 Model . It describes the essential
information about the WR-Z16 hardware, its features, and configuration options.

It is designed to allow users who have their first contact with the device to easily connect it
to a management network and distribute precise timing (PTP or White Rabbit (WR), for
example) through optical interfaces. It also provides advanced tips for expert users and/or
details how to match the security policies defined at your company.

The set of official manuals also includes the

WRZ- OS API guide

for complete doc-

umentation about your WR-Z16.

About WR-Z16

The WR-Z16 is the reliable precise time fan-out for the most demanding time distribution
applications on 1G Ethernet-based networks.

The WR-Z16 is a standalone device with 16 SFP connectors which provides sub-nano-
second accuracy time over plug-and-play fiber links. It provides very precise IEEE 1588
(PTP) in all its optical interfaces and supports NTP interoperability. Picosecond-level fre-
quency distribution is available through digital clock. The WR-Z16 incorporates failover
mechanisms which combine multi-source redundancy and holdover capabilities to ensure
continued operation.

Its design is optimized for datacenter environment, where it is typically located in the top of
the hierarchy level of the distribution network. The WR-Z16 can obtain the external time
reference from its 10MHz and 1PPS SMA inputs, from another White Rabbit device
through the SFP ports or it can work as a free running master device for the network.

A typical intra-datacenter network topology is shown in the figure below, where the WR-
Z16 is working as the grandmaster and is the key element for distributing the timing
through WR to each cabinet of the datacenter. Different end nodes are included in the dia-
gram to illustrate the interoperability with different interfaces.
