Troubleshooting an Operational Problem

a. If the ASN is in a stack, make sure the SPX slot dial on the rear panel

of each ASN points to a different slot ID. Turn the selector in either

direction so that the arrow on the selector points to the ID you want

to use (F

setting.

If the SPEX

Net Module does not support hot-swap, make sure that

a terminator plug connects to any unused ports labeled SPEX IN and

SPEX OUT. Make sure the thumbscrews on the terminator plug are

tight.

If the ASNs are in a stack and they do not support hot-swap, you must

terminate the SPEX IN port of the ﬁrst ASN and the SPEX OUT port of

the last ASN. Make sure that for the remaining ASNs in the stack, the

SPEX OUT port of one ASN connects to the SPEX IN of the next.

Note: The ASN cables are long enough to skip one ASN in the stack for

troubleshooting purposes.
