CHAPTER 1 • VelaSync 1232 User Manual

1.1 Product Overview

1.1  Product Overview

VelaSync® 1232 High-Speed Time Server is an enterprise-class time serving appliance designed for high-frequency trading and other network applications that require low latencies.

VelaSync’s customized configuration, comprising state-of-the-art network synchronization software, precision GNSS (GPS) timing technology, and reliable server hardware allows it to provide high-performance time management over multiple network interfaces.

VelaSync 1232 (part number 1232-xxxx-xxxx) is the latest version of this unit. For the user manual for an original VelaSync 1225 (part number 1225-xxxx-xxxx) see the VelaSync User's Manual, archived on the Spectacom website.

Hardware

The customized Supermicro® server platform is a 1U server comprised of a standard chassis and motherboard, as well as a GNSSreceiver plus oscillator (OCXO, or Rubidium), two hard disks (RAID), two power supplies, and several time, frequency, and communication ports.

Software

The pre-installed Spectracom time synchronization and management software allows to distribute very accurate time throughout a network, supporting NTP and PTP protocols. In day-to-day operation, the software allows system administrators to centrally monitor time synchronization accuracy throughout the network in an efficient manner.

1.8.2  SAFETY Advisories

DANGER! ELECTRICAL HAZARD — DO NOT OPEN THE ENCLOSURE: No

user-serviceable parts inside (the product warranty will be voided, if the Seal is broken). Should you ever decide to open the enclosure at your own risk, unplug and remove BOTH power supplies first (the POWER button will NOT de-energize the system!).

Caution: Only trained and qualified personnel should be allowed to install,

replace, or service this equipment.

DANGER! — GROUNDING: A reliable ground must be maintained at all

times. To ensure this, the rack itself should be grounded. Particular attention should be given to power supply connections other than the direct connections to the branch circuit (i.e. the use of powerstrips, etc.).

Caution: CIRCUIT OVERLOADING — Consideration should be given to the

connection of the equipment to the power supply circuitry and the effect that any possible overloading of circuits might have on overcurrent protection and power supply wiring. Appropriate consideration of equipment nameplate ratings should be used when addressing this concern.

DANGER! Hazardous voltage or energy is present on the back panel when

the system is operating. Use caution when servicing.

Caution: Do not use power supplies other than the p/s model installed in

your VelaSync, and do not mix power supplies with different power ratings.

NOTE: Replacement power supplies can be purchased directly from Spectracom (Part no. PS09R-

070J-SL01).

Please be sure to also consult local and national electrical codes, and the User's Manual of the Original Equipment Manufacturer which can be accessed online under:
