Introduction

PRISMA VelaSync® High-Speed Time Server is an enterprise-class time serving appliance

designed for high-frequency trading and other network applications with low-latency re-

quirements.

VelaSync’s customized conguration, comprising network synchronization software, pre-

cision GNSS timing technology, and reliable server hardware allows it to provide high-

performance time management over multiple Ethernet interfaces at speeds of up to 40 Gb.

This Quick Reference Guide is a supplement to the main user manual

warnings under: manuals.spectracom.com

Electrical hazard. No user serviceable parts inside. Do NOT open panel

before unplugging BOTH power supplies rst (the POWER button will not

de-energize the system!)

WARNING

CAUTION

Do not use power supplies other than the model installed in your Vela-

Sync, and do not mix power supplies with dierent power ratings.

In the unlikely event of a power supply failure, a replacement unit can

be procured directly from Spectracom (part no. PS09R-070J-SL01).

Mechanical Installation

Each of the two rack rail assemblies comprise an inner chassis rail (pre-installed to the

server chassis), and an outer rail that needs to be mounted to the rack:

1. Measure the distance from the front rail to the rear rail of the rack. Attach a short

bracket to the front side of each of the outer rails, and a long bracket to the rear side

of each outer rail.

2. Adjust both the short, and the long brackets to the distance measured earlier so that

the rails t snugly into the rack. Secure the short bracket to the front side of the outer

rail with two screws, and the long bracket to the rear side of the outer rail with three

screws. Take note of the locking tabs, which prevent the server from sliding out too far

out of the rack.

3. Line up the rear of the inner rails at the chassis with the front of the outer rails at the

rack. Slide the server chassis into the rack, keeping the pressure even on both sides.

Depress the locking tabs, if needed (they will click upon proper engagement).

TELCO rack installation: Use two L-shaped brackets on either side of the chassis. Deter-

mine a balanced front-to-back position of the chassis. Remove bezel from server, if installed.

Attach the two front brackets to each side of the chassis, then the two rear brackets, leaving

enough space to accommodate the width of the telco rack. Slide the chassis into the rack,

and tighten the brackets to the rack.

VelaSync™Quick Reference Guide

Connecting the GNSS Antenna

Connect a GPS/GNSS antenna system to the GNSS connector (see page 4, rear panel

illustration, item number 7), using the supplied Type-N antenna cable, and an LMR-400

equivalent cable with surge suppressor and active GPS L1 antenna, such as Spectracom

model 8230.

Note the GNSS receiver connection provides 5 VDC power for the antenna.

Connecting Power

Plug in both power supplies. (You may hear a fan noise from inside the housing).

Swith the unit on by pressing the ON/OFF button on the front panel. Wait for the device to

boot up.

Once the boot process is completed, only the green POWER status LED should be lit.

CAUTION

If only one power supply is running, and the other one is inserted all

the way, but not plugged in, or defective, VelaSync will emit a long

BEEP, so as to alert you of a problem with the backup power.

Establishing a Network Connection

To communicate with PRISMA Vela Sync without using DHCP, connect a PC with a

congured LAN port via Ethernet cable to the VelaSync server using ETH0. The unit is

shipped with one static IP address: ETH0 = 192.168.1.1

To connect and set up a device using DHCP, connect to an Ethernet port without a static IP

address (any Ethernet port except ETH0). Find the unit on your network by contacting your

network administrator, and log in to the unit’s assigned IP address. Log on to the Web UI

(see directions in the next section).

6VelaSync™Quick Reference Guide

VelaSync also has a command-line login available on its serial port, which can be used as

an alternate way to initially communicate with the unit.

To connect using the serial port, connect a PC to the serial port of the VelaSync using a

null-modem cable. The VelaSync serial port operates at 9600 baud, 8 data bits, No parity, 1

stop bit.

For more information on the Command Line Interface (CLI), see the main PRISMA VelaSync

manual.

Operation

NOTE

For more detailed information pertaining to VelaSync’s Web UI opera-

tion, please consult the VelaSync User’s Manual, found online under:

manuals.spectracom.com

The Web UI

In addition to a CLI, VelaSync has an itegrated web user interface (Web UI) to congure and

monitor the unit, that can be accessed from a network-connected computer, using a standard

web browser.

Start a web browser, and go to 192.168.1.1 (or the IP address assigned to the unit

in Establishing a Network Connection) in order to log into the Web UI. It is also

recommended that you change the default static IP address. You can do so in the Web UI under

MANAGEMENT > Network Setup. Select the gear symbol next to each Ethernet port for

options.

On this screen, you can turn DHCP on or o for each port. If the DHCP function is disabled on

an Ethernet port, you can manually reset the IP address.

The default login credentials are:

User name = spadmin

Password = admin123

NOTE

CAUTION

For security reasons, please change the default password

immediately by navigating to the MANAGEMENT menu > Change

My Password.
