information about cabling.
1.3.1 The PCI Interface
PCI is a high-speed standard local bus for interfacing a number of I/O
components to a PC processor and memory subsystem. The PCI
Interface Descriptions 1-3
functionality for the LSI21003 is contained within the LSI53C1010-33.
The chip connects directly to the PCI bus and generates timing protocol
in compliance with the PCI specification.
The PCI interface operates as a 32-bit DMA bus master. The connection
is made through edge connector J1 (see Figure 2.1). The signal
definitions and pin numbers conform to the PCI Local Bus Specification
Revision 2.2 standard. The LSI21003 conforms to the PCI universal
signaling environment for a 5 V or 3.3 V PCI bus.
1.3.2 The SCSI Interface
The SCSI functionality for the host adapter is also contained within the
LSI53C1010-33. The chip connects directly to the two SCSI buses for SE
or LVD SCSI applications and generates timing and protocol in
compliance with SCSI standards. One SCSI interface operates at a burst
transferrateofupto40Mbytes/sforwideUltraSCSItransfers,andthe
other up to 160 Mbytes/s for wide Ultra160 SCSI transfers.
Channel A is SE only with active autosensing termination. The
Channel A interface is made through connectors J2, J3, and J4.
Connector J2 is a 68-pin high density right-angle receptacle for internal
SCSI connections. Connector J3 is a 50-pin high density right-angle
receptacle that protrudes through the ISA/EISA bracket. Connector J4 is
a 50-pin narrow (ribbon) internal connector.
Channel B may be either SE or LVD with active termination always
enabled. The Channel B interface is made through connector J5. J5 is a
68-pin high density right-angle connector for internal SCSI connections.
See Figure 2.1 on page 2-5 for the location of these connectors.
The LSI21003 supplies SCSI bus TERMPWR through a blocking diode
and self-resetting 1.5 A short circuit protection device.
A 40 MHz oscillator on the host adapter provides the clock frequency to
the LSI53C1010-33 that is necessary to support SCSI transfers.
1-4 Using the LSI21003
1.3.3 SCSI Activity LED Interface
The SCSI activity LED interface is a four-wire arrangement that allows
connection of an LED harness to the board. The connector on the host
adapter is J6 for both channels. See Table 3.8 on page 3-12 for the signal
name and pin numbers on this interface.
1.3.4 Cabling
The cable provided in the kit is matched for a Fast/Ultra/Ultra2/Ultra160
SE or LVD operation. This cable also has built-in multimode (SE/LVD)
termination since most Ultra160 hard disk drives are not made with
on-board LVD termination.
Table 1.1 lists standard cable specifications.

1. This parameter may be exceeded in point-to-point and engineered
applications.
2. LVD was not defined in the original SCSI standards for this speed. If all
devices on the bus support LVD, then 12-meter operation is possible at
this speed. However, if any device on the bus is SE only, then the entire
bus switches to SE mode, and the distances in the SE column apply.
3. SE and High Voltage Differential (HVD) are not defined at greater than
Ultra speeds.

slots.
A 32-bit slot should be used. The LSI21003 will work in a
64-bit slot, but only 32 bits are used. The host adapter requires
a PCI slot that allows bus master operation. See Figure 2.2 on
page 2-6.
Step 6. Remove the blank bracket panel on the back of the computer
aligned with the PCI slot you intend to use.
Save the bracket screw for securing the installed board.
Step 7. Carefully insert edge connector J1 of the host adapter into the
PCI slot. Make sure the edge connector is properly aligned
before pressing the board into place. See the example in
Figure 2.2.
Note:
You may notice that the components on the PCI Host
Adapter face the opposite way from those on other non-PCI
plug-in boards you have in your system. This is correct, and
the board is keyed to go in only one way.
Step 8. Secure the board with the bracket screw before making the
internal and external SCSI bus connections (see Figure 2.2).
Step 9. If you are connecting any internal SCSI devices, plug the end
of an appropriate internal SCSI ribbon cable into the connector
