CFP4207E (WIDE, 80-pin Single Connector Attachment [SCA])

External Terminator Power

The interface connector carries both power and ground so a separate TERMPWR
interface line is not provided.

Internal Termination

This version of the drive has no on-board termination so the drive must be
externally terminated. Alternative 2 active termination is recommended.
Alternative 1 passive termination is not suitable for this application.

Cable Requirements

This version of the drive is designed to interface directly to a mating connector
which is on a passive back plane or directly into a motherboard. The same
guidelines relative to impedance, stub length and distance between stubs apply
for SCSI bus signal reliability. These guidelines may not be directly translated
to a back plane design so these design rules are to be viewed with respect to the
intended purpose of controlling reflections and the propagation of signals down
the bus. Since the characteristics for PCB signal traces are affected by trace
width, proximity to ground, and trace routing, careful review of the back plane
design and analysis of signal quality is highly recommended.

Connector Requirements

The drive's connector will mate with a AMP Champ 2-557103-1 vertical
receptacle or the AMP Champ 2-557101-1 right angle receptacle.

Single Connector Attachment (SCA) Signal Definitions

Power

Four +12 Volt signals provide the +12 volt power to the drive. The current
return for the +12 volt power is through the +12 Volt Ground signals. The
maximum current that can be provided to the drive through the +12 Volt signal
pins is 3 Amperes. The supply current and return current must be distributed
as evenly as possible among the pins. The maximum current is while the drive
motor is starting.

Three +5 Volt signal pins p5 volt power to the drive. The current return
for the +5 volt power is through the +5 Volt Ground pins. It is expected that the
+5 Volt Ground will also establish the digital logic ground for the drive. The
maximum current that can be provided to the drive through the +5 Volt signal
pins is 2 Amperes. The supply current and return current must be distributed
as evenly as possible among the pins.

These specifications refer to the connector's characteristics. Refer to Chapter 2
for the drive's power requirements.
