CPS-8910 Description
The CPS-8910 is a 1U rack-mountable PCI Express 10-port switch. It has a Gen 2
PCI Express x8 upstream port, a Gen 1 PCI Express x4 upstream port, and eight Gen 1
PCI Express x4 downstream ports to enable linking any PCI Express host to multiple
expansion chassis or peripheral devices.
The following figure shows the key features of the CPS-8910 front and rear panels.

What You Need to Get Started
The following items are included in the device kit:
• Cabled PCI Express Switch Box x4 10 port
• Rack-mounting brackets
• CPS-8910 Getting Started Guide
• 12 V, 24 W power supply
Note If you are using the CPS-8910 with fiber optic cables, you must
purchase a 12 V, 50 W power supply with the proper connection from a
different source. Refer to the Specifications section of this document for power
supply connector information.

The following items are available on ni.com:
• Copper or fiber optic PCI Express cable
Note The maximum copper cable length for the x8 upstream port is 3 m. All
other copper cables have a maximum length of 7 m. Refer to the
Electromagnetic Compatibility Guidelines section for more information.
Unpacking the Kit
Caution To prevent electrostatic discharge (ESD) from damaging the device,
ground yourself using a grounding strap or by holding a grounded object, such as
your computer chassis.
1. Touch the antistatic package to a metal part of the computer chassis.
2. Remove the device from the package and inspect the device for loose components or any
other sign of damage.
Caution Never touch the exposed pins of connectors.
Note Do not install a device if it appears damaged in any way.
3. Unpack any other items and documentation from the kit.
Store the device in the antistatic package when the device is not in use.
Electromagnetic Compatibility Guidelines
This product was tested and complies with the regulatory requirements and limits for
electromagnetic compatibility (EMC) stated in the product specifications. These requirements
and limits provide reasonable protection against harmful interference when the product is
operated in the intended operational electromagnetic environment.
This product is intended for use in industrial locations. However, harmful interference may
occur in some installations, when the product is connected to a peripheral device or test object,
or if the product is used in residential or commercial areas. To minimize interference with
radio and television reception and prevent unacceptable performance degradation, install and
use this product in strict accordance with the instructions in the product documentation.
Furthermore, any changes or modifications to the product not expressly approved by National
Instruments could void your authority to operate it under your local regulatory rules.
Caution To ensure the specified EMC performance, operate this product only with
shielded cables and accessories.
Caution To ensure the specified EMC performance, the length of all I/O cables
must be no longer than 100 m (328 ft).

Caution To ensure the specified EMC performance, do not connect the power
input to a DC mains supply or to any supply requiring a connecting cable longer
than 3 m (10 ft). A DC mains supply is a local DC electricity supply network in the
infrastructure of a site or building.
Installing the CPS-8910 in a Rack
The CPS-8910 comes with adjustable rack-mount ears for front or rear-facing installation, as
shown in the following figure. Complete the following steps to install the CPS-8910 and
connect devices to it.
Caution When mounting the equipment in the rack, do not create a hazardous
condition due to uneven mechanical loading.
1. Mount the CPS-8910 in the desired position by installing the rack-mount ears and
tightening the four rack-mounting screws as shown.
Figure 2. CPS-8910 Rack-Mount Ear Installation
2. Connect the 12 V power supply to the CPS-8910.
3. Connect the PCI Express host device to either the x8 or x4 upstream port connection.
4. Connect up to eight PCI Express expansion systems or devices to the x4 downstream
ports.
5. Power on the chassis or computer containing the PXI Express or PCI Express host.

Providing Adequate Clearance
Apertures along both sides of the CPS-8910 facilitate cooling.
Place the CPS-8910 in an instrument rack so that the apertures have adequate ventilation.
Keep other equipment a minimum of 76.2 mm (3 in.) away from the air outlets on the sides of
the CPS-8910.
