Overview
This document explains how to install the CPS-8910.
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 dierent 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
2 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
Notice 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.

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.
