1 Introduction

1.1 Product Definition

The cPCIS-2501 3U CompactPCI 6-slot Cubic Chassis is designed for 3U CompactPCI cards and modules without rear I/O. It is 4U in height, 237 mm deep, and suitable for bench top use or wall mounting. It is ideal for industrial or transport applications where small chassis size and versatility are important. A built in cooling system with removable filter provides maximum cooling efficiency, and the 250W cPCI power supply allows easy maintenance. The cPCIS-2501’s ability to handle a wide range of temperatures and excellent shock and vibration characteristics make it suitable for operating in a rigorous environment.
This user’s manual provides unpacking, operating, and maintenance information for the cPCI-2501 3U CompactPCI 6-slot Cubic Chassis. The cPCI-2501 chassis is assembled using the following components:

2 Getting Started

In this chapter, we will describe the unpacking procedure for the cPCIS-2501 and installation procedures for CompactPCI boards and power supply unit (PSU).

2.1 Shipping Contents

Check the shipping carton for any damage. If the shipping carton and contents are damaged, please notify the dealer for a replacement. Retain the shipping carton and packing material for inspection by the dealer. Obtain authorization before returning any product to ADLINK.
Check that the following items are included in the package. If there are any missing items, please contact your dealer:
One cPCIS-2501 chassis
cPS-H325/AC power supply
This user’s manual
Power cord (either N. American or European)

2.2 CompactPCI Board & PSU Installation

CompactPCI connectors are rigid, and therefore require careful handling when inserted and removed. Improper manipulation of the cards will result in damage to the backplane.
System slots usually have obvious indicators (e.g. red card guide rail, triangle mark enclosing the slot number on the backplane, etc.). System cards can only be installed in a system slot. Do not insert a system card into any other slot, or insert any peripheral card into system slot.
The PSU slot also has an obvious indicator such as a green card guide rail in a standard CompactPCI chassis (see photo below).
The handle on CompactPCI cards and PSUs ensures simple and safe installation and removal. Please follow the procedures below to install a CompactPCI module into the cPCIS-2501 chassis:
Getting Started 5
CompactPCI Card Installation/Removal Procedure
1. Place the chassis on a level surface. Remove the blanking plates where required by undoing the retaining screws at each end. Retain the blanking plates for possible future use. The system should not be put into use without blanking plates for all empty slots, otherwise the EMC and cooling performance will be compromised
2. Hold the SBC module, peripheral card or PSU module vertically. For PSU modules, make sure that the handle is unlatched (i.e. that it is pulled downwards) by first pressing on the locking button with your thumb.
3. Carefully insert the module into the desired slot by sliding the edges of the board into the appropriate card guide rail. Take care to ensure correct alignment of the card with the chassis during insertion to prevent damage to the card and/or backplane.

Peripheral Card Slots
4. Continue inserting the card until the handle engages with the chassis.
5. Pull upwards on the handle for final insertion. For PSU modules, ensure that the locking button on the handle is fully latched into position. Fasten the retaining screws at each end of the card (2 for single slot cards, 4 for double slot cards).

2.3 Powering Up the System

Set the main power switch in the lower right corner of the rear panel to the off position ( O ). Set the secondary power switch front panel socket on the back of the chassis. The supplied PSU is full range 90-240VAC and does not require input voltage setting. Insert a system module and any desired peripheral cards into the appropriate card slots.
To power up the system, set the secondary power switch on the front panel to the on position (
to the off position ( I ). Connect the supplied power cord to the
