Step 4: Attach Peripheral Devices
Overview
After you have installed the components in a chassis, attach peripheral devices to the SCB and
XIO, if present
The tables that begin on
connectors.
Always power-off the system and disconnect all power cords from their source before
connecting or disconnecting cables for peripheral devices.
When attaching devices to the EPC-3321, certain considerations must be made:

Serial
Parallel
USB
EIDE or
IDE
SCSI
Floppy
PS/2

•
These ports are 9-pin male D-Sub connectors on the I/O panels.
•
One serial device can be attached to each 16550-compatible serial port.
•
These ports provide an RS-232 interface.
•
These devices can only be attached to the SCB or the transition I/O module
•
These ports are 25-pin female D-Sub connectors on the I/O panels.
•
The IEEE 1284 port provides a Centronics compatible printer interface.
•
AT-compatible / Bi-directional / EPP / ECP operations are supported.
•
These devices can only be attached to the SCB or the transition I/O module
•
The USB bus will support up to 127 USB devices, which can be attached in a daisy-chain
configuration.
•
This SCB supports two USB controllers; one on the front SCB panel, one on the rear XIO panel.
•
A single USB cable cannot exceed 5 meters (16.4 feet) in length.
•
The 5-pin male shrouded, keyed header on the board surface can connect to the Series "A"
connector on the I/O panel.
•
Software drivers appropriate to the OS will be needed to operate USB devices. RadiSys does not
supply such drivers.
•
Up to two EIDE or IDE devices can be attached to each EIDE header on the XIO.
•
The BIOS will support up to four EIDE or IDE devices. For more information on IDE operations,
see
page
24.
•
Up to 15 SCSI devices can be attached to the XIO on a 68-pin (Ultra Fast/Wide) connector.
•
Up to 15 SCSI devices can be attached to the XIO on a 50-pin (Ultra Fast/Narrow) header.
•
SCSI devices must be connected in a daisy-chain configuration with proper termination.
•
Only one of the three SCSI connectors can be used at any one time.
Up to two floppy drives can be attached to the XIO Floppy Disk Drive (FDD) header.
•
A PS/2 mouse and/or keyboard can be attached to the corresponding 6-pin female mini-DIN
connectors on the front or rear I/O panels.
•
These devices can only be attached to the SCB or the transition I/O module
•
The video connectors on the front and rear I/O panels are 15-pin D-Sub female type.
•
A standard VGA or SVGA interface is provided.
•
Two display devices can be attached to the SCB and XIO at the same time, but video intensity will
be slightly reduced for each device.
•
The Ethernet connectors on the front and rear I/O panels are 8-pin RJ-45 type.
•
Two Ethernet connections can be made, but only one will be active; the BIOS will select one.
•
Two LEDs on the SCB I/O panel indicate the status of Ethernet operations:
Activity: This LED indicates either data transmit or receive activity. When activity is occurring,
•
the LED is lit. When activity ceases, the LED will fade.
Link Integrity: This LED indicates whether a valid link is established with the Ethernet controller
•
in either 10 or 100 Mbps. When the link is valid, the LED is lit. When the link has failed or is
invalid, the LED will fade.
Pin 1 on the XIO is the +5 V (+) signal; Pin 2 is the Speaker (-) signal.
•
This 10-pin male, shrouded header on the XIO provides the interface to an I
•
Pin 8 is the Clock signal; Pin 10 is the Data signal.
•
The modem connector on the XIO is a 4-pin female RJ-11 type.
•
Four LEDs on the rear I/O bracket indicate the status of modem operations:
Receive Data (RXD)
•
Transmit Data (TXD)
•
•
Data Carrier Detected (DCD)
Data Terminal Ready (DTR)
•
When using a flat cable to attach a device, the colored trace for Pin 1 on the cable must align with Pin
1 on the header/connector. See
•
The cable attaches the System Reset Button on the SCB Faceplate to JP1 on the SCB. See
