Cascade ports use standard RJ-45 connectors and straight through CAT5 cables to
connect chassis, but use Viavi proprietary protocol to communicate between cascaded
units.
USB Ports
Standard USB type A connector may be used with any USB 2.0 device. This includes the
USB system recovery drive for second generation Xgig1000 chassis.
3.0 USB type A connectors may be used with any USB 3.0 device.
3.0 USB type B connector may be used with an external host as a Management port for
USB administration.
Clock Ports
The Clock Out port provides a means of using the clock out signal to measure the eye
diagram of the output signal from the Analyzer. The Clock Out port accepts a SMA-type
cable.
The Clock In port functionality is TBD. This port is reserved for future use.
Port Connectors
The Xgig1000 has two female mini-SAS HD connectors on the front. One connector is typi-
cally used for connection to the target, and the other is used for connection to the host.
Either port can be used for the host or the target. Standard mini-SAS cables are supplied
with the system.
The signals from a mini-SAS connector can be split into single-port outputs (or, single-port
inputs can be consolidated into a mini-SAS connector) by using a “hydra” type cable. Using
a hydra cable, the chassis can be configured to monitor between a single host and up to
four drives.
Front Panel Reset Button
To safely shutdown the operating system and power off the chassis, press and hold the
Front Panel Reset button for two seconds until the System LED starts blinking yellow.
Stop pressing the button as soon as you see the System LED blink. This will allow the
system to do a graceful shutdown.
NOTE
A USB driver is installed as part of the installation package. If you choose to connect the
chassis using a USB extension cable, you may be prompted to re-install the USB driver.
