Power-On

When the Terminal is first powered on, the CPU obtains its software and the software for

all of the circuit cards from hard disk. Since the software is stored on hard disk and not in

PROMs, Zetron can update any installed terminal with just a phone call.

Once the software is loaded, and the CPU has tested the cards for proper operation, the

Model 2100 and Model 2200 goes “online” for paging. The CPU continually polls the

microprocessors on the phone and radio interface cards for any required service. The

distributed multiple microprocessor of the Model 2200 dedicates intelligence right where

it is needed. Each processor guarantees instant service to a phone caller or radio. Multiple

processors also mean that as the system is expanded with more cards, more computer

power is also added to keep throughput high and clients happy.

Power-On

Following installation by qualified radio service personnel, turn on the Terminal. The

power switch for the Model 2200 is on the right side panel; for the Model 2100 and Model

2200EX it is on the front left (under the front cover). Various lights on the front of the

circuit cards will come on and the unit will perform a built-in self-test. Upon completion

of the self-test (about 30 seconds), the circuit cards’ software is automatically loaded from

the hard disk. Lights on the front of the cards blink as the cards are selected by the CPU

and loaded with their software. This software loading process takes about seven seconds

per circuit card type.

The Model 2100 and Model 2200 is now ready for paging use. During normal operation,

the SELECT and TEST3 lights on input cards (Trunks and Multiports) will both flash in

sync with each other as the CPU stays in communication with each card’s microprocessor.

Various status lights on each card indicate hardware activity such as incoming phone calls

and outgoing radio paging messages. Refer to Series 2000 Paging Terminals Installation

and Maintenance for details on the status lights.
