1. INTRODUCTION
The STLITE-CPCI-8R(+) and -16R(+) are expansion chassis having either eight or sixteen slots for expanding
the Compact Peripheral Component Interconnect (CPCI) local bus of a Compact PC computer system. If more
than sixteen additional slots are required, additional chassis can be daisy-chained together. A CPCI Expansion
Chassis is transparent to the user. The expansion chassis complies with the Compact CPCI Local Bus
specification.
With standard usage, no special driver or software support is required to install and use Compact CPCI boards in
the STLITE-CPCI-16R Expansion Chassis.
The expansion chassis provides special features not usually found in expansion chassis. These include:
• Backplane temperature monitoring.
• Power supply voltage monitoring.
• Optional individual card-slot temperature monitoring (16R+ and 8R+ models).
• An optional rack-mounted cooling fan housing having four fans.
• Fan current monitoring for the optional fans.
The basic expansion chassis consists of a standard rack-mounted enclosure, a circuit board for installation in the
host computer, and a three-foot shielded ribbon cable to connect the two.
Figure 1-1 shows the functional relationships of both model versions and special features of the unit.

2. COMPONENTS – STANDARD SYSTEM
The STLITE-CPCI-16R (Figure 2-1) consists of the following major components:
Figure 2-1. STLITE-CPCI-16R
2.1 CPCI EXPANSION MOTHERBOARD
The expansion motherboard is a printed circuit board mounted vertically in the back of the rack enclosure. It
receives bus signals from the host computer and places equivalent signals on the chassis secondary buses. There
are either eight or sixteen slots on the secondary bus for installing boards. Each group of eight slots is serviced
by an Intel 21150-AC, 32-bit, 33 MHz bridge chip.
A semiconductor sensor is provided on the expansion motherboard for temperature monitoring. Its output is
applied to an A/D converter along with power supply voltages (±12V, +5V, and +3V). If the optional fan tray is
used, two voltage signals from two pairs of DC-powered cooling fan are applied to the A/D for conversion.
Optionally, each of the eight (or sixteen) card slot locations has a semiconductor temperature sensor mounted
over it. The sensors are mounted on a PCB strip mounted on the top of the chassis. Signals from these sensors
are converted to digital values by a second A/D. The digital values, along with other monitor data, are sent to the
host computer over the expansion cable.
2.2 HOST BRIDGE CARD: STLITE-PCI-HOST; STLITE-CPCI-HOST
The Host Bridge card is a PCI or CPCI adapter card that can be installed in any open slot in the host computer.
The Host Bridge card is connected via a three-foot shielded ribbon cable to an expansion bridge card in the back
of the STLITE-CPCI-8R/16R Expansion Chassis.
2.3 POWER SUPPLY
The STLITE-CPCI-8R/16R incorporates a standard 250-Watt, ATX-type switching power supply in the cabinet.
A cooling fan is integrated in the power supply. All four output voltages are monitored to an accuracy of ±2%.
The power supply operates on either 115 or 230VAC (switch-selected).
2
2.4 EXPANSION CABLE
The STLITE-CPCI-8R/16R is supplied with a STLITE-C-3 cable. This is a shielded three-foot cable for
connecting the host bridge card to the expansion chassis bridge. The connectors are 80-pin, D-type. Longer
cable lengths are neither advisable nor available.
2.5 CABINET
The STLITE-CPCI-8R/16R chassis is totally enclosed in a heavy-gauge aluminum rack-mounted enclosure. To
access a card slot, remove the filler plate for that slot by backing out the two captive screws.
A standard AC jack is mounted on the rear panel next to the AC power ON/OFF switch. An AC voltage-select
switch is provided to select power supply operating voltage (115 or 230VAC).
3. INSTALLATION & START-UP – STANDARD SYSTEM
3.1 PRELIMINARY INSTRUCTION
CAUTION
All CPCI cards are susceptible to damage from electrostatic discharges. When carrying cards,
always keep them in their anti-static packaging. When setting a bare card down, place it on an
anti-static surface. We strongly recommend using a grounded wrist strap and/or working on a
grounded floor pad.
3.2 HOST BRIDGE CARD INSTALLATION
There may be a bank of several switches on the host card (S1). These switches should be left as set at the
factory (all switches to the right – toward the edge of the card).
1. Remove power from your host computer system.
NOTE: Do NOT disconnect the power cable. Doing so removes the ground connection.
2. Remove the computer’s cover. Refer to the system owners manual if necessary.
3. Insert the Host PCI/CPCI Bridge card in any available card slot. Secure the card.
4. Install slot covers on any open backplane locations.
5. Replace the computer cover. DO NOT APPLY POWER YET.
3.3 CARD INSTALLATION - EXPANSION CHASSIS
With no power applied to either the host computer or the CPCI Expansion chassis, remove the aluminum filler
plate(s) for the desired slot(s). We recommend configuring all unused slots with filler plates.

3.4 CPCI EXPANSION CABLE INSTALLATION
1. Position the chassis within easy reach of the three-foot cable.
2. Attach the cable to the Host Bridge card. Secure it firmly by tightening both captive thumbscrews on the
connector.
3. Attach the cable to the Chassis CPCI Bridge card located on the rear of the chassis. Secure it firmly by
tightening both captive thumbscrews on the connector.
CAUTION
The CPCI expansion cable is a specially fabricated cable having a sheath of shielding around the wire ribbon. It
is somewhat stiff and can be damaged if handled roughly. Use care when installing it.
Avoid making any sharp bends or pinches.
3.5 CPCI CARD INSTALLATION
1. POWER-DOWN. Make sure that no AC power is applied to the expansion chassis or host computer.
2. PROTECT AGAINST ELECTROSTATIC DISCHARGE. Before handling CPCI boards, put a grounding
wrist strap on. If a grounding floor mat is available, use it.
3. CPCI card addresses are set up by BIOS software. Typically, it makes no difference which slot is used,
unless specified by the card manufacturer. Carefully press the card fully into the slot connector, secure the
latch, and install the securing screw in the backplane bracket.
NOTE: Not all CPCI cards may work universally in any slot. If a problem is experienced, try using a
different slot or re-order the existing card sequence.
The large number of CPCI cards and device drivers available make it impossible to fully test and certify
every card from every manufacturer for use in the STLITE-CPCI-8R/16R. To avoid possible problems,
always require that the CPCI card vendor provides certification that the cards comply with PICMG 2.0 R2.1.
Compliance of your entire systems to this specification is highly recommended and will be your best
assurance of a trouble-free system.
3.6 CABLE INSTALLATION
1. Use great care when connecting and routing cables to avoid damaging the conductors (this is especially
important for ribbon cables). Strive to keep cables as short as possible, but leave enough slack (or “service
loops”) easy installation and removal.
2. Avoid running signal cables and power cables next to each other.
3. If noise pick-up is a problem, re-locate the cable runs or use shielded cables.
3.7 FINAL INSTALLATION CHECK
1. Check the installation before powering up for the first time. The power supply has an over-voltage
protection circuit. However, it may not trip in time to protect a device that has been improperly hooked up
or whose power cable has been damaged.
2. Check that the AC Voltage select switch on the rear panel of the CPCI-Expansion Chassis is set for the
correct voltage (either 115 or 230VAC).
3. Attach the AC power cable to the CPCI-Expansion Chassis.
