Viper II - V2Frame

User Manual

Quick Start Guide

The Viper II frame is designed for "plug and
play" use. The Power Bus System allows for
the convenient placement of modules in any
orientation that suits the user.

The frame ships ready-to-use. Simply insert
your PS5000 Power Supply Unit and the
optional PS5010 Battery back-up unit, if
provided. The rear of the PS5000 features a
Power Entry Module that must be set for your
local AC power. A convenient window on the
module shows the voltage input setting, either
115 or 230 VAC. If adjustment is necessary,
see the Power Supply section on page 3.
Note that the frame can accommodate
additional PS5000's or PS5010's to ensure
uninterrupted power to your system. The
PS5000 ships with a North American type
power cord. You may need to replace this with
the appropriate IEC cord to accommodate
your local power outlets.

Once the power supplies have been properly
configured and inserted into the rack frame,
AC mains power can be supplied and
additional modules can then be inserted.
Modules can be hot-swapped at any time
without fear of damage. Care should be taken
when inserting modules to ensure that they go
in straight since improper insertion can result
in damage to the internal backplane power
connectors, explained further on page 2.

Viper II Rack

General

The Viper II rack Frame (V2) is a 19" 3 RU
card cage designed to house the entire
line of Telecast Viper II modules. Each
frame has 16 slots that can be used to
accommodate both single and double-slot
modules and power supplies. Assuming
two slots for the main PS5000 power
module, the user is left with 14 slots for
functionality modules with the option of
adding multiple PS5000 or PS5010 Battery
Back-Up power modules for further
insurance against power outages.

The V2 frames uses a power bus system
using the "Future-Bus 24-pin header"
giving the user flexibility in the placement
of modules in the frame. The pinout for the
Future-Bus connector is shown at right.

The frame features a hinged front security
bar that is used to secure the modules.
The bar is locked down using the two
spring-screws located on each side of the
hinged panel.

Unpacking

To ensure that no damage occurs to the
V2 frame during shipment, it is packed and
shipped without modules inserted. Care
should be taken when removing it from its
packing materials. Inspect the unit closely
for loose screws, smooth hinge operation,
missing nylon card guides and/or cosmetic
damage. Any problems should be reported
to Telecast immediately.

To return an item for repair, call Telecast at
508-754-4858 to obtain a return material
authorization (RMA).

Note that the frames undergo an alignment
procedure during assembly and testing.
Any movement of the backplane will result
in the possibility of damaged pins in the
power connectors. Do not make adjust­ments to the position of the backplane
panel!

The Future-Bus Connector

DC power is
supplied to the
frame via a 24­pin "Future-Bus"
connector. When
looking into the
frame, the pin­outs are as
indicated in the picture to the right. The top
two rows of 4 pins are 0V Ground. The
middle two rows are for 10-18VDC OUT
and the last two rows are reserved for
future expansion of the Viper II system.

CAUTION: Care should be taken when
inserting and removing modules as these
pins are of a very fine pitch and can easily
be bent. If pins do become bent, contact
Telecast for an RMA number as it is not
recommended that the user attempt a
repair as failure to properly align the
backplane will result in additional bent
pins.

Installing Modules

The installation and removal of modules is
a very straight-forward process but, as
mentioned above, care should be taken to
ensure that no damage occurs as a result
of an improperly inserted module.

Each frame is equiped with nylon card
guides for each of the 16 slots. In cases
where the module is two spaces in width,
only the left-side guide is used.

Carefully align the module in the top and
bottom guides and slowly insert it. As the
rear end of the module nears the rear of
the frame, it will hit a riser-plate that serves
to lift the module so that the power
connectors will properly come together and
seat. You will "feel" this plate as you insert
the module and as you continue to insert it
you will "feel" the female power connector
on the module make smooth contact with
the male power plug in the frame. Any

attempts to 'slam' the module into the
frame is likely to result in bent pins.

Converting "Throw-Down" Modules

Any of the Telecast Viper II "throw-down"
modules can easily be converted to fit in a
Viper II frame. A Rack Mount Kit (RMK) is
all that is required to make such a conver­sion. As the picture below illustrates, the
kit includes a metal spline with ST barrel, a
short ST-ST jumper cable and the frame
faceplate with a ribbon cable to transfer
LED indicator information from the module
to the new faceplate.

Installation involves removing the back
cover from the throw-down module. It is
secured with three machine screws. Once
the rear plate is removed, the module
simply installs onto the new spline with the
same three screws.

If you are converting a digital module, care
should be taken to ensure that the EMI
gasketing remains in position as the back­plates are exchanged. Failure to do so
may increase the probability of RF/EMI
leakage from the module. Care should
also be taken in connecting the ribbon
cable and in the routing of the fiber jumper.
A pinched or too-tightly-coiled jumper
could impede optical performance.

When making this conversion, be sure
keep the old back-plate in a safe place for
future re-conversion back into the throw­down configuration.

Caution should be taken to ensure that the
hinged security bar is up and in the locked
position when modules are not being
installed. Failure to do so may result in
modules falling out of the frame if it were to
be inadvertantly tilted or moved.

Note the three holes
used in securing the
module to the spline
and the ST fiber
jumper and ribbon
cable that must be
attached.
