2.
Insert the connector at one end of the second SPEX-HS cable (Order No.
7166) into the SPEX-HS Port C on the ASN at the bottom of the stack.
Tighten the thumbscrews.
3. Insert the next connector on the second SPEX-HS cable into the
SPEX-HS Port C on the next ASN in the stack. Tighten the thumbscrews.
4. Repeat Step 2 for the remaining nodes in the stack.
Figure

Caution: To enable dual bus cable support for a SPEX-HS net module, your
router must be running Bay Networks Router Software and Boot PROM
Version 10.0 or later (or BNX Software and Boot PROM Version 6.00 or later),
and diagnostic PROM (asndiag.exe) Version 2.16 or later.
If your router is not running these minimum versions, it will not recognize the
second port.
To upgrade your diagnostic PROM, use the Technician Interface
prom
command. (Refer to Using Technician Interface Software if you use router
software or Troubleshooting and Testing if you use BayStream software.)
