PART 4. POWER UP PROCEDURES

4.1 CONNECT POWER TO THE SYSTEM

During the initial installation, it is best to verify proper system operation before plugging in any
amphenol-type cables to the MDF. If you have already plugged the cables in, unplug them.
Verify that the AC voltage at the dedicated electric outlet is in the range of 220VAC. Make sure the
AC power switch is in the OFF position and that the RAM pack battery switch is OFF. Plug the KSU
power cord into the dedicated polarized AC outlet. Turn the AC power switch to the ON position. The
LED on the power supply will light steady to confirm the presence of power. If the PSU LED fails to
illuminate, unplug the system, remove the power supply and check the AC fuse located on the
b o t t o m .
If the fuse is good but the LED does not illuminate, you must correct the problem before continuing.
Turn off the power switch. Unplug all cards using the card ejectors. Turn the system on. Check the
LED again. If the problem is corrected, you have a defective card. Test and remove the faulty card
before continuing. If the LED still does not light, unplug the KSU and change power supplies. This in
all probability will solve the problem. If it does not, contact Samsung Technical Support.
4.2 RAM CARD INDICAT I O N S
Having verified proper operation of the power supply, visually check the RAM card indications. The
LED should flicker rapidly indicating the main processor is functioning. The battery switch should
now be turned ON.
The system is equipped with a halt program. When this program is running, the LED is ON steady.
The system must be reset to release the halt program and restore the system to normal operation.
See MMC 810 for operation of the halt program.
4.3 PCB VERIFICAT I O N
Before connecting all MDF cabling, plug in a test cable to the first DLI port. Connect a digital
Telephone set and verify that it is working. Use maintenance program MMC 805 to verify the system
version, software version and that all cards are recognized by the CPU. Remove the test cable and
plug in all amphenol-type cables to the MDF. Proceed with the rest of the installation.

4.4 DEFA U LT TRUNK AND STATION NUMBERING

Upon initial power up, the CPU reads each slot for the existence of a card and identifies the type of
card. It stores this as the default configuration.
The system assigns trunk numbers beginning with 701 and continues to 704 for a basic KSU or to
710 for a fully equipped KSU.
Station numbers are assigned in the same manner. The lowest station is assigned station number
201 and continues to 208 for a basic KSU or to 222 for a fully quipped KSU. Keyset daughter boards
