Routine Maintenance Procedures
555-233-123 5-98 Issue 4 May 2002
Swapped Routes, End System Identifiers, or Fiber
between a PPN and an EPN
Symptoms
■
An incorrectly-connected EPN TN230X does not complete board insertion.
■
Dial tone is present on end stations on the PPN and on correctly-connected
EPNs, but no dial tone is present on the affected EPN end stations.
■
Calls cannot be made between the PPN and the correctly connected
EPNs, because talk paths cannot be routed correctly.
Diagnostics
1. The show switch circuittable command on the A500 shows VBR control
channels from the A500 port intended for the incorrectly-connected EPN
(but actually connected logically or physically to the PPN) that should not
exist.
Action
1. Correct the ATM addresses (or swap fibers) on the A500 between the
incorrectly-connected PPN and EPN.
Swapped Routes, End System Identifiers, or Fiber
between two EPNs
Symptoms
■
All TN230Xs complete board insertion.
■
The PPN cold starts both incorrectly connected EPNs as usual.
■
Both EPNs log many
WRONG BOARD INSERTED
errors (use list
configuration all or display circuit-packs <carrier>) providing the EPNs
actually do have different boards configured in the same slots.
■
Some end stations may work if they are connected to the correct board in
the same slot on both EPNs. Otherwise, end stations on the PPN have dial
tone, while end stations on the EPNs do not.
■
All A500 diagnostic commands look good.
Diagnostics
1. Check log for
WRONG BOARD INSERTED
errors (use list configuration all
or display circuit-packs <carrier>).
