2-22 Preparation for DHS Installation
Preparation for DHS Installation
Installation Overview
1. Plan the installation, including the KSU and Main Distribution Frame (MDF) location,
station locations, cable runs, and optional equipment.
2. Mount a backboard in the designated MDF location.
3. Mount the KSU on the MDF backboard. Use the provided mounting template to aid in
spacing the mounting screws.
4. Install optional 3 x 8 Modules inside the KSU as required.
5. Install the Option Module if required.
6. Mount the MDF backboard and attach the punch-down terminal block(s) on the
backboard.
7. Run cables for the key telephone and single-line telephone locations from the MDF
to each location. No cable should loop from one telephone location to another.
8. Run wiring to any optional equipment, such as external paging equipment, loud bell
signaling devices, music sources, etc.
9. Route telephone and CO line port interface connections through the appropriate
KSU opening, and terminate all industry standard wiring on punch-down terminal
block(s) on the MDF.
10. Route auxiliary device cabling through the appropriate KSU opening and terminate
as required (music source, printer/computer for SMDR, external paging equipment,
etc.).
11. Terminate station cables on punch-down terminal block(s) on the MDF.
12. Terminate station cables on modular jack assemblies at the station locations.
13. Cross-connect the CO lines and station ports to station cables on the corresponding
punch-down terminal block.
14. Install the station instruments and any optional station equipment, such as headsets
or SLTs.
15. Set the RAM memory initialization switch from its factory set OFF position to the ON
position (refer to Figure 2-12: DHS Components ).
16. Plug the AC power cord into the dedicated AC outlet and power up by operating the
AC power switch to the ON position.
17. Observe the power/CPU heartbeat LED for flashing status after 4-6 sec.
If the RAM Initialization switch was not in the OFF position prior to this installation, it must
be moved to the OFF position and allowed to stay in the OFF position for 2 minutes while
the system is NOT powered. This critical step is detailed in
”Power Up Sequence"
near the
end of this chapter.
