1.3 Interface Descriptions
This section provides a more detailed explanatio n about the PCI
Interface, The SCSI Interface, and Ultra SCSI.
1.3.1 The PCI Interface
PCI is a high-speed standard local bus f or interfacing a numb er of I/O
components to the processor and memory subsystems in a high end PC.
The PCI functionality for the SY M22801 is contained within the Sy mbios
SYM53C876 PCI to Ultra SCSI I/O Processor chi p. The SYM53C876
connects directly to the PCI bus and generate s timing protocol in
compliance with the P CI specification.
The PCI interface ope ra tes a s a 3 2- bi t DM A bus m as ter. The connection
is made through the edg e connector J1 (see Figure 2.1) . The signal
definitions and pin numbers confor m to the PCI Loca l Bus Specific ation
Revision 2.1 standard. Th e SYM22801 conforms to t he PCI universal
signaling environ ment for a 5 V or 3.3 V PCI b us.
1.3.2 The SCSI Interface
The SCSI functionality for the SYM22801 is contai ned within the
Symbios SYM53C876 PCI-Ultra SCSI I/O Process or chip. The
SYM53C876 connects directly to the two SCSI bu ses and generates
timing and protocol i n compliance with the SCS I standard.
The SCSI interfac es on t he SYM22 801 operate s as 1 6-bit, s ynchronou s
or asynchronous, si ngle-ended bus, and supp ort Ultra SCSI protocols
and 16-bit arbitrati on. Ea ch in ter fac e is m ade th rough two (and only two)
of the connectors J 2, J3, and J4 (for Channel A), or J6, J7 , and J8 (for
Channel B). Connectors J2 and J6 are 68-pin hi gh density right-angle
receptacles. Connectors J3 and J7 are shielded 68-pin V HDCI 0.8 mm
right-angle receptacle s that protrude through th e back panel bracket.
Connectors J4 and J8 are 50-pin low dens ity vertical shrouded pi n
headers. See Figure 2.1 for the location of these conn ectors.
Single-ended SCSI ac tive termination is prov ided on the SYM22801
board. Termination is automatic ally enabled when only o ne of the
connectors J2 , J3, and J4 ( or J6, J7, and J 8) is used, or when an 8-bit
device is connected to the 16-b it J3 or J7 connectors . In the latter case,
Interface Descriptions 1-3
1.3.3 Ultra SCSI
only the upper 8 d ata bits are automatically terminated. Th e SYM22801
supplies SCSI bu s TERMPWR (termination powe r) through a blocking
diode and a self-reset ting 1.5 A short circuit p rotection device. The
onboard LED lights when TERMPWR is shorte d. Separate switc hes for
each channel allow user override of termination .
A 40 MHz oscill ator is installed on the SYM22801 to provide the c lock
frequency to the SYM53C8 76 that is necessary to support Wide Ultra
SCSI transfers o f up to 40 Mbytes/s.
The SYM22801 has full support for Ultra SCSI as well as supporting Fast
SCSI simultaneously. Ultra SCSI is an extension of the SCSI-3 famil y of
standards that expan ds the bandwidth of the SCS I bus, allowing faster
synchronous data tran sfers. Special SCSI cabl es are specified for
operation with Ultra SCSI dev ices, and you must consider th e total
number of devices and the length of the S CSI bus when setting up your
system. See Chapter 2, In stalling the SYM22801 Hos t Adapter for a
detailed explanation of SCSI bus connections .

do not touch board components or gold connector contacts.
The use of a static gro und strap is recommended.
Step 4. Locate the slots for PC I plug-in board installa tion.
Refer to the user ’s manual for your computer to confirm the
location of the PCI s lots. The SYM22801 require s a PCI slot
that allows bus master operation.
Step 5. Remove the blank panel on the back of the computer aligned
with the PCI slot you intend to use. Save the bracket screw.
Step 6. Carefully inse rt the edge connector J 1 of the host adapter into
the PCI slot. Make sur e the edge connector is pr operly
engaged before pressing the board into place. See the example
shown in Figure 2.1.
Note:
You may notice that the components on a PCI host adapter
face the opposite way from those on other non-PCI adapter
boards you have in your system. This i s correct, and the
board is keyed to go in only one way.
Step 7. The bracket around the conn ectors J3 and J7 (see Fig ure 2.1)
should fit where the bl ank panel was removed. Sec ure the
bracket with the bracke t screw before making th e internal and
external SCSI bus c onnections.
Step 8. If you are conne cting any interna l SCSI devices, plug a 68-pi n
connector on the e nd of the internal SCSI ribbo n cable into
connector J2 or J6 for Wide SCSI, or a 50-pin connect or into
connector J4 or J8 for normal SCSI (see Fi gure 2.1). Make
certain to match pin-1 on both connectors.
Note:
It is possible to use both internal co nnectors on a c hannel
if no external devices are att ached to that chan el. You may
use only two of the thre e connectors on each chan nel at
once.
Step 9. Connect your computer’s LED cable if desired. This is designed
to drive the front panel L ED found on most PC cabi nets to
indicate activity o n the SCS I bus. See Table A.5 in Appendix A
for the signal name an d pin numbers for this LED interface.
