SAFETY WARNINGS

LASER RADIATION

The laser transmitters emit invisible radiation that can cause permanent eye
damage. A VOID DIRECT EXPOSURE T O BEAM. Operate only with
the proper optical fiber installed in the transmitter optical connector. The laser
transmitter should be disabled with the front panel switch whenever the optical
connector is empty .

HIGH VOLTAGE

The AC input power supply contains no user serviceable parts. There is exposed high voltage inside the

supply . The power supply housing should be opened only by factory service technicians.

FIRE HAZARD

The AC input rear power supply fuse is a 3AG, 3.25A, slow blow fuse. T o avoid a risk of fire, this fuse

should be replaced only with an identically rated fuse.

The main chassis is not intended as a shipping container. Shipping the system with any module installed can

cause severe physical damage.

MODULE EXTRACTOR LP-EX 010-000930

A system can have a single power supply or 2 redundant supplies. W ith a single power supply, a fully populated
system holds 15 RF/optical modules. With dual power supplies, a fully populated system holds 14 RF/optical modules.
All modules can be hot swapped.

OPTICAL CONNECTORS AND CLEANING

The fiber ends can be damaged by the insertion of contaminated connectors. Some types of customer
damage to connectors or fiber are not covered under warranty . Fiber connectors should never be left uncovered.
Reel cleaners or prepackaged alcohol wipes are the most convenient means of cleaning optical connectors. Clean
alcohol and lint free wipes or swabs may also be used.

The standard optical connector is an SC/APC. T o specify an FC/APC connector , append –F A to the
model name and consult the factory for part numbers. FC/APC connectors must be specified at time of order .

CHASSIS

The chassis is a 19” rack mount unit, 5.75” (3 RU) high. The chassis slots are numbered 1 to 16 from left
to right as viewed from the front. When viewed from the rear, slot 1 is on the
RF/optical modules. Slot 16 accepts only a power supply module. Slot 15 accepts either an RF/optical module or
a power supply module.

All module changes can be made from the front of the chassis through service loops in the RF and power
cables. All RF connections are made from the rear of the rack. All optical connections are made from the front of
the rack. There are access holes in the front sides of the chassis for fiber routing. There are fiber support slots in
the top front of the chassis.

right. Slots 1-14 accept only

There are no connections or test points on the front of the chassis. The chassis status LED’ s are located on
the power supply module. All LED’ s can be seen through a clear window in the front of the chassis. All normal
indicators are green. Any red LED that is turned on denotes an abnormal condition.

The chassis rear has 4 long-life fans that can be changed from the outside. The OT P/N for the fan
assembly is 037-000405. There is a DB-25M alarm connector at the center rear of the chassis. These isolated
relay contacts, rated at 100mA @ 25VDC, provide a ground closure on any alarm, including power failure. Pins 1­15 monitor slots 1-15 respectively . Pin 17 is the chassis cooling alarm. Pin 24 is the summary alarm that alarms on
any failure. Pin 25 is ground.

The small rectangular connector at the right rear of the chassis is for factory testing, the Olson T echnology
SNMP interface (LP-SNMP), or OEM status monitoring modules.

STATUS MONITORING

There are three types of status links built into this system.

1) The rear panel DB25 connector provides isolated summary alarms of each module in the system. No

computer is required.

2) The 10 pin connector located in the upper right rear of the main chassis, can be adapted to the printer

(parallel) port of any windows 95 or 98 (ME, 2k, and XP will not work) based computer to monitor

several critical module and chassis functions. This software is available from Olson T echnology Inc.

3) The 10 pin connector will accept an OT -SNMP SNMP interface. One interface is required per chassis.

Please consult the factory for complete details on these features.
