TECHNICAL MANUAL
PART 9. CHANGING SOFTWARE

9.1 REPLACING THE EPROMS

The first thing you should do before proceeding is to discharge any static electricity
you may have gathered by touching a ground point such as the cover of the KSU
Power Supply. When you have done this then check the iDCS MEM3 card and ensure
that the memory switch is in the ON position. Next turn the KSU off and disconnect the
backup batteries, if equipped, from the power supply. Remove the iDCS MEM3 card by
gently pulling on the card ejectors. Lay the iDCS MEM3 card face up on a non-
conductive surface.
NOTE: It is advisable to use PCMMC to produce a backup copy of the customer
database before turning the system off in case problems arise and the original
database on the iDCS MEM3 card is lost.
Gently remove the EPROMS from the iDCS MEM3 card using a chip extraction tool or
by gently prying with a small flat bladed screwdriver. Set the removed EPROMS aside
carefully in case they need to be reinstalled
Remove the new EPROMS from their protective packaging and confirm that the legs on
the EPROMS are straight. If the legs are not straight, contact Samsung Technical
Support for assistance. Carefully insert the new EPROMS in their designated sockets.
Install the MEM3 card and plug in the 25 pair cable for P1 of the motherboard.
Switch on the KSU and verify that it is operating. If the KSU does not operate, remove
the new EPROMS and reinstall the old EPROMS and test again. If the system still fails
to operate, contact Samsung Technical Support.

(
MEM4 ONLY)
When a software change is required, it must be done via PCMMC through the LAN
interface. Please refer to the PCMMC Technical Manual to perform a software upgrade
for a MEM4 card.
