5.0 Installing The Syncronization Card
On The Services Board
Whenever you install one or more DXPT1 boards, and the DXP Plus is receiving its timing signals from an
external source, you must install one synchronization card (DXOPT–SYN) on the services board using the
following procedure.
NOTE: Whenever you install one or more DXPT1 boards, and the DXP Plus is receiving its timing signals from
an external source, you must install one synchronization card (DXOPT–SYN) on the services board. When
you connect the system to central office (CO) lines, you must include a synchronization card, and the DXP
Plus must be controlled by CO signalling. In installations where the DXP Plus supplies the clock signal
for the distant system, there is no requirement for DXOPT–SYN cards and you do not need to perform this
procedure.
1. Switch off the DXP Plus power supply, disconnect the AC power cord from the AC outlet and disconnect the
optional battery back-up assembly from the main cabinet power supply
2. Install your static discharge wrist strap on your bare wrist; adjust it for a snug fit. Be sure that the strap is
touching bare skin and is not isolated by clothing. Connect the wrist strap cord between the wrist strap and an
AC or earth ground
3. Loosen the retaining hardware and lift the front panel away from the common equipment cabinet.
NOTE: With the common equipment in the installed position, the ground lug on the side of the cabinet is an
appropriate grounding point since it should have a heavy ground wire connected between it and a good
earth ground.
CAUTION
Do not remove or install the services board while the DXP Plus is powered-on or severe system problems
may occur.
4. Locate the services board, loosen the retaining screws, remove it from the main cabinet, place it in a static
protection bag, and transport it to the static-safe work area.
5. At the static-safe work area, with your wrist strap in place, remove the services board and the DXOPT–SYN
card (if used) from their static protection bags.
6. Refer to the illustration, and install the DXOPT–SYN card at the top position on the services board with the
supplied hardware. (Actually, you can use any of the three positions; however, other non-related option cards
require installation in the lower positions so it is best to leave these positions open for those other uses.).
7. Use the method detailed in Section 5.1 to set the strapping switches on the services board. If you wish, refer to
step 8 for details, and transport the board assembly to the cabinet installation site before you set the strapping
switches.
8. Place the services board with the newly installed DXOPT–SYN card into a static protection bag and transport
the assembly back to the main cabinet.
