FOR YOUR SAFETY
Before undertaking any troubleshooting, maintenance or exploratory procedure, read carefully the
WARNINGS and CAUTION notices.
This equipment contains voltage hazardous to
human life and safety, and is capable of
inflicting personal injury.
If this instrument is to be powered from the AC line (mains) through an
autotransformer, ensure the common connector is connected to the neutral (earth
pole) of the power supply.
Before operating the unit, ensure the conductor (green wire) is connected to the
ground (earth) conductor of the power outlet. Do not use a two-conductor extension
cord or a three-prong/two-prong adapter. This will defeat the protective feature of the
third conductor in the power cord.
Maintenance and calibration procedures sometimes call for operation of the unit with
power applied and protective covers removed. Read the procedures and heed
warnings to avoid “live” circuit points.
Before operating this instrument:
1. Ensure the proper fuse is in place for the power source to operate.
2. Ensure all other devices connected to or in proximity to this instrument are properly grounded or
connected to the protective third-wire earth ground.
If the instrument:
- fails to operate satisfactorily
- shows visible damage
- has been stored under unfavorable conditions
- has sustained stress
Do not operate until, performance is checked by qualified personnel.

Chapter 1
GETTING STARTED
Product
Description
The Model 1261B High Power Intelligent Mainframe is a 13-slot
VXIbus Mainframe. It fully complies with the VXIbus Specification
1.4 requirements and is VXIplug&play compatible.
Key Features Figures 1-1 through 1-8 show the key features of the 1261B.
Ease of Use · Fast Setup. The 1261B backplane uses active-automatic
VME interrupt acknowledge and bus grant daisy chaining.
Manual configuration of backplane switch settings or jumpers
has been eliminated.
· Universal AC Input. The 1261B AC input is both auto-voltage
and auto-frequency ranging. The chassis does not require the
configuration of a voltage selection switch.
· Visual System Health Status Indication. The 1261B comes
standard with system monitoring that gives you key system
health status (Voltage, Current, Airflow and Temperature) on
the front panel display. Monitored parameters include
temperature rise on each slot, fan speed, power supply voltage
and currents.
· Enhanced Monitoring. The optional micro-controller based
Enhanced Monitoring System (EMS) adds a fully VXIbus
compliant message-based interface, an auxiliary RS-232 port,
and VXIplug&play drivers. The alpha-numeric display that
comes with the EMS provides detailed system status
messages.
· Plug-in Power Supply, Fans, and Monitor. The 1261B
modular system design results in a virtually wireless mainframe
with low MTTR and high MTBF. See Figure 1-3.

· Variable Recess Rack Mounting. The adjustable rack mount
ear provides variable (0.625 inch increments) recess rack
mounting capability. See Figure 1-8.
· Fan Speed Control. The 1261B delivers the cooling air that
your application requires. Fan speed control reduces acoustic
noise levels of the 1261B high performance cooling system.
