CHAPTER l
INTRODUCTION

THE COMPUTER l!'ITERCONNECT

The Computer Interconnect (Cl) is a high-speed, serial data bus used to link computer subststems (nooes)
to form a Cl duster. Typicaliy, the cluster i.s confined to a computer room environment. Nodes may consist
of CPUs, memory, a'ld intelligent mass 1'torage, communication, and data acquisition sl'bsystem3 Features
of the Cl include:
'"
"
•
•
•
•
•

Dual signal paths capable of simultaneous operation
70 meg,~bit/sec path bandwidth
Low error rates
PackeHiriented 1rans;,;i•sion
lmmedialeiy ackno·11ledge; successful packe1 <eceipt
Cont~ntion arbitration (light !.:lading)
Round-robin arbitration (heavy loading)

Each node withi1i z Cl cluster connects to the Cl via an interface that provides two separate signal paths
(Figure l·I) Dual paths provide a high de~ of da•.a availabihty between nodes. One pair of nOl!tS can
comm•J'licate over one path (path A), while another pair of nodes comrnunieiites over the se<:<md patr (path
B).

A single Cl path consists of a }lair of bu.~ cables (rine for transmit, one for ieceive). These cables oonnect z
node and the :ign~I distribution coupler for tha l path. For each path, a central Star Coupler (SC008)
receives the data tr·nsmitted by a node and distribute< thi£ data to the other nodes within the cluster.

1.2 THE 0780 !NTERfACE

The Cl780 interface connects the Synchronous Backplane Interface (SBJ) of a h061 VAX· I I/780 system
to lhe Cl \Figure 1·2)

NOTE

Prim11r~ PrOCt'SSOr.
T!Je Ci780 is an i'l(ell:gcnt in'.~rrace that functions as a buffered comrr.'.!nicauo:is port. ll uses the queue
~ructures pro. ;..:..-0 under the VAX/VMS operatbg sy~tem to transfer messages and blocks uf d;-t.a
uetwoen !he host :>ym:m\ rr> .. morv and other nodes 11.ithin the Cl cluster. By providing the ne;;cssary data
buffering, addre:-~ translation, and serial encoding/decoding, the CI780 rcdu.::es the amount of overhead
svftware pr<:X'essirg required 10 complete typical high-level intercomputer communications.

The CJ780 may be installed in any 4 in"1 option slot in either the standard CPU cabinet or H9602-H "B!

backplane to JI through 16 on the adjacent backplane to the right of the Cl7SO.
CAUTION
Always connect SBI jumper cables witb the
..SIGNAt" lal!el on the outside of the loop.

NOTE

If the Cl780 is the first option iutalled ia an

Two sets of TX/RX bulkhead cable assemblies are supplied with the Cl780; one set for signal path A ,P/l\
7018527-00), and the other for signal path B ( P/N 7017 527-01 ). These cables should be rothcJ and con·
nected from the back of the cabinet.
I.

Mount the bulkhead connector plate of each cable assembly, from the inside. to the MASSBUS
'utouts on the 1/0 panel at the boltom or the cabinet. Refer to Figure 2-11 (CPU cabincti or
Figure 2·12 (H9602-H expansion cabinet) for details.

Secure th< TX/RX B bulkhead connector plate to the first available cutout on the n~ht

avoid any sharp bends, kinks, or twists :n the cables (Figure 2·11 or 2-12).

Pia~~ a P-clamp over each cable, just behind the pin plug on the end, and carerully insert the

INTkOOlJCTION

,A,cccptance testmg of the (1780 is b;1sically a two-step p1occdure:
i.

The newly installed Cl780 is operationally verified stand-alone (not connected to the CO.

(he wstem is ccnnected to the Compurer Interconnect. and operationally verified as a node with·
in 1i,~ ~:J cluster.

Stand-alone verification consists of running the sy~tem microdiagnosti~-s. which contain Cl780 ,;upport,
followed by the cr~o Level 3diagnostic•.
Operational verification of the system within the Cl Cluster consists of:
L

Connecting the r.o<le to the Cl and ve.rifying the connection by running the Cl Exerciser (CIE)
pro!!ram (EVXCJ).

::?.

Running a copy of the U~·!r Environmental Test Package (CETP) on the node under test.

If all \'AX nodes within a CJ duster art> being tested,

l. FTP must he run on earh node.
3.2 Cl780 CHECK-OUT PROCEl>URE (STANl).ALONEI
To verify the Cl780 installation:

Before loading the diagnostics, make lhc following corniecrions to the 1/0 connector panel at the bad of
the. cabinet:

lhing ont of the attenuator pads (P/N 1219907-01) and two of the SCOOf> modularity cubics

nec1inn to the RECEIVE A bulkh.:acl rnnnectilln.

Perform the same connection for path B using the other attenuator pad and two SC008 modularity cables from the Cl780 CD Kit to connect TRANSMIT B to RECEIVE B.

Use the following procedure to load the diagnostic programs into the system.
I.

Put the VA X-11 /780 in a stable, halted condition.

lnitii11i1e and unjarn the SBI via 1hc console commands:
)}) !NIT
)}) UNJAM

Load the Diagnostic SupcrvisN, ESSAA.EXE, vi~ the .:ommand BOOT (or LOAD
ESSAA.EXE/ST:FEOO), from the diskette, or BOOT it from the system disk.

Load the diagnostic program using LOAD ESCGA.

Attach the device to be tested:
DS) ATTACH Cl780 SBI UNIH (PAAO) TR (14) BR (4) NODE (0)

Select the unit 10 be tested via the cm 'mand SELt.CT (UNIT #).

Set any desired supervisor flags.

Start the diagnostic program.
NOTE
Diagno.>tics l:SCGB and E..'iCGD contain manual
inttrvtnlion tt5t stetions. Tu run them once lht diagnostic Is loaded, type
DS) START/SECTION:MANUAL

ind perform tht required manual actions listed by
the diagnostk printout.
When running the diagnostics for the first timt after
installing the Cl780, run them in ascendin1 ordtr
from ESCGA to ESCGD and indudt the manual
intervention test sections.

After successfully running the four diagnostics, remove the attenuator pads and mcdularity
cables from the 1/0 panel bulkhead 1.:.:innectors.

10.

Locate the Cl bus cables (BNCIA-XX) and connect one end of each cable to the appropriate
bulkhead connector.
NOTE
00 NOT unroll or route the Cl bus cables at this
time.

11.

Connect the two attenuator pads to the free ends of the Cl cables. Be sure to connect
TRANSMIT A to RECEIVE A and TRANSMIT B to RECEIVF B.

3·2

12.

Run the EXTLOOP section of diagnO!\tic ESCGD five times to test the Cl cables prior to routing and conn<-cting them to the SC008 by typing:
DS) START /SECTION:MANUAL/PASS:5

lJ.

Disconnect the Cl bus cables from the bulkhead and remove the 1wo attenuator>.

14.

Carefully unroll, route, and connect the Cl bus cables to the SC008 and the C!780 bulkhead.
Refer to Section 2A of the SC008 Star Cuu,iler Users Guide for the cable routing procedure.

I 5.

Rerun the EXTLOOP section of diagnostic ESCGD five times to verify the cable connection',.

3.3 ON·LINE TESTING OF THE Cl780 AND THE Cl CLUSTER
I.

Use the procedure described in Appendix C to update SYE with the SYE update kit surplied in
the Cl780 software box. (BX-Q3J 13·TE) and the console Ooppy diskette with the Cl780
microcode.

Run the CI Exerciser program, EV XCI. Refer to the procedure Installing and Running the Cl
Exerciser Software (A V-T3 l l.l\-TE) supplied in the Cl780 sofw:ire box for operating
instructions.

Run UETP on each VAX node where a Cl780 has been installed. Refer to the VAX/VMS

The PFAR register contains the memory addn:ss at which a failure occured after a MSE or DSE interrupt.
or, after a response with buffer memory system error status. This addn:ss may be the exact address, an
addreM in the same page as the failing address, or, in the case or DSE interrupts, and address in some part
10 the data structure. for DSE i•1terrupts, PFAR contains a virtual address or offset; for MSE interrupts
and b;.:ffer memory system errors, the PfAR contains a physical address. PESR may contain further information about the contents of PfAR for DSE interrupts. Figure 8-6 illustrates the register format.

The PESR register indicates which type of error resulted in a DSE interrul't. This register is read only by
the port driver and is valid after a DSE interrupt. Table 8-6 describes the contents of this register.
