5.2.2 Option Card Field Installation Instructions
Typically, SecureSync units are shipped with custom-ordered option cards pre-
installed at the factory. In the event that an option card is purchased at a later
time, you need to install it yourself, following the instructions below.
5.2.2.1 Field Installation: Introduction
SecureSync time and frequency synchronization system offers customizability
and expandability via the addition of a range of modular option cards. Up to 6
option cards (depending on your unit specifications) can be accommodated to
offer not only synchronization to a variety of input references, but also numerous
types of output signals, supporting an extensive number of traditional and con-
temporary timing protocols including:
digital and analog timing and frequency signals (1PPS, 1MHz/5MHz/10MHz)
timecodes (IRIG, STANAG, ASCII)
high accuracy and precision network timing (NTP, PTP)
telecom timing (T1/E1), and more.
Note: The installation procedure varies, depending on the type of
option card and the installation location to be installed.
5.2.2.2 Outline of the Installation Procedure
The general steps necessary for installing SecureSync option cards are as follows:
1. If adding or removing option cards that provide a reference, optionally
backup your SecureSync configuration (refer to "[2]: Saving Refererence
Priority Configuration" on page370, if applicable to your scenario or envir-
onment.)
2.
Safely power down the SecureSync unit and remove the top cover of the
main chassis (housing).
