Introduction Chapter 1
The EPC® -6315 PrPMC (Processor PCI Mezzanine Card) uses the RadiSys 82600
integrated chipset to bring an Intel Architecture processor into ultra-dense form
factors.
With the ability to accept a type I Compact Flash device, the EPC-6315 can
be a completely self-standing processor in any application.
The EPC-6315 includes an 800MHz Pentium III processor with up to 512MB of
on-board SDRAM. The EPC-6315 also features ECC protection of memory with
single-error correction and double-error detection capability. Performance is
maximized with the standard 133MHz PSB and 133MHz memory bus. For
maximum flexibility, the EPC-6315 leverages the dual mode PCI-to-PCI bridge
capability of the RadiSys 82600 to automatically configure the bridge based on the
strapping of the slot on the baseboard. This capability allows the EPC-6315 to
become a Monarch PrPMC, and provide PCI bus enumeration and service
interrupts on the PCI bus or a non-Monarch PrPMC and function as a PCI-based
auxiliary processor.
The Jn1 and Jn2 connectors provide a 32-bit 33/66MHz interface to the PCI bus on
the baseboard as well as providing power and ground. The optional Jn4 connector
provides a full set of I/O, which includes EIDE, COM, and keyboard/mouse
interfaces. The front panel provides 10/100BASE-T Ethernet connector and
Compact Flash socket.

Configuration and installation Chapter 2
This chapter describes how to install an EPC-6315 PMC on a RadiSys EPC board.
For information about... Go to this page...

Avoid causing ESD (electrostatic discharge) damage by following these
conventions:
• Keep the blade in its anti-static bag until you are ready to install it.
• Install the blade (as described later in this chapter) only in a static-free
environment:
• Before touching the blade, attach an ESD wrist strap to your wrist and
connect its other end to the ESD friction-lock connector at the shelf’s lower
left.
• Remove the blade from its antistatic bag only in a static-free environment.
• Avoid touching printed circuits, connector pins, and components. Where
possible, hold the blade only by its edges or mounting hardware.
• Make the least possible movement with your body to minimize electrostatic
charges created by contact with clothing fibers, carpet, and furniture.
• Keep one hand on the shelf, if possible, as you insert or remove a blade.
• Avoid placing the blade on the shelf cover or on a metal table. The cover
and metal table increase the risk of damage because they provide an
electrical path from your body through the blade.
The EPC-6315, like most other electronic devices, is susceptible to ESD
damage. ESD damage is not always immediately obvious. It can cause a partial
breakdown in semiconductor devices that might not result in immediate failure.

Before you begin
The EPC-6315 requires a PMC carrier.
Installing the EPC-6315 PMC on the carrier card
You install the EPC-6315 PMC on the carrier card as shown below.
To install a PMC module:
1. Remove and save any blank faceplate from the PMC slot in the carrier card
faceplate.
2. Position the PMC bezel through the PMC slot on the front panel.
3. Push the rear connectors into the carrier card.
4. Insert and tighten the screws on the back of the carrier card.

Using the 3-pin connector
The EPC-6315 includes a 3-pin connector that you can use to access some
COM1 signals.
Before you begin, ensure that you have a null-modem cable that connects the 3-pin
connector to your terminal.
To use the 3-pin connector:
1. Attach the cable to the 3-pin connector and your terminal.
2. Start a terminal emulation program, such as Hyperterm or Telix, using
these settings:
Baud rate: 115200
Parity: None
Data bits: 8
Stop bits: 1
Flow control: None
You can now access the BIOS setup program using the methods described in
Chapter 4, BIOS configuration.
You must construct this cable; RadiSys does not supply a cable for the
3-pin connector. For pinout information, see
3-pin connector on page 76.

Maintaining and upgrading the EPC-6315
Occasionally you will want to perform maintenance or upgrades on the EPC-6315.
When this occurs, you must remove the board from the carrier card, repair or install
the desired option, then re-install the board on the carrier card. The following
section describes how.
Disconnecting the EPC-6315 PMC from the carrier card
To separate the EPC-6315 from the carrier card:
1. Remove screws on the back of the carrier card.
