Power-Up Initialization (Cold Start) - Comdial DX-80 Technical Manual

Circuit boards are susceptible to damage caused by electrostatic
discharge. You must keep this in mind as you handle the circuit
boards. Refer to Comdial publication IMI01-005, Handling of Electrostatically
3. Locate the CPM and "SMDR" serial port on the CPM.
4. Connect the male end of the 9-pin serial cable into this SMDR port.
5. Connect the other end (female) of the 9-pin serial cable to the PC/collection device serial port.
6. Replace the KSU cover.

2.18 Power-up Initialization (Cold Start)

roper operation of the DX-80 system requires that the system be initialized at the time of start up.
P
The installation of the DX-80 is complete only when this critical operation is performed. Occa-
sionally it may be required to perform this initialization process after the original installation, but this
is rare.
Initialization causes the operational customer database to be established and organized for system
operation and future updating. At the time this procedure is complete the default database contents are
loaded into operational memory. The system is ready to run on this database configuration. Cus-
tomized changes may be made to this database according to the allowable program settings for the
various features. Note: If you are performing a cold start on a system with an existing customized
database, be sure to back up that database prior to beginning the cold start procedure. The cold start
procedure forces the default database into the DX-80 switch, overwriting any existing database
residing on that switch. For more details on backing up databases, see the DX-80 Technical Manual,
Volume II, Programming.
To initialize the DX-80, perform the following steps.
1. If you have previously plugged in the power cords and/or turned on the power supplies, turn
OFF the power supply to the DX-80 KSUs and un-plug the DX-80 AC power cords on KSU1
and KSU2.
2. Remove the KSU cover (four screws at each corner) of KSU1 and KSU2 (if adding optional
modules).
3. Connect a static discharge wrist strap to a suitable earth ground. Be sure that the strap is touch-
ing bare skin.
