6633.0. "TRI-LINK ?" by HSOSS1::KENNEDY () Mon Apr 28 1997 12:40

    Just a quick sanity check.  I have a customer that currently has a
    single HSJ40 and wants to install another for dual-redundancy.  
    Instead of running another set of CI cables, I have suggested that
    he acquire a tri-link connector and cable kit, so that we can daisy
    chain the HSJ40s and use the single set of CI cables.
    
    His VAR is telling him that the tri-link is only supported on HSDs
    and HSZs.  
    
    I believe the tri-link is also supported on the HSJs.  The procedures
    for replacing controllers and write-back cache mention the tri-link.
    
    Any assistance you can provide would be appreciated.

	Your VAR is correct; Tri-Links are only used in HSD and HSZ configurations. HSJ's need the CI `pigtail' and cannot be daisy-chained.
