SN-CONF (Switch Node Configuration)
A switch node carrier c ontains:
■Up to 16 Switch Node Interfac e (SNI) TN573 circuit packs in slots 2
through 9 and slots 13 through 20
■One or two Switch Node Clock (SNC) TN572 circuit p acks in slots 10 and
12
■An Expansion Interface (EI) TN570 circuit pac k, a DS1 Converter (DS1C)
TN574 circuit pack, or no c ircuit pack in slot 1
■An optional DS1 CONV circuit pack in slot 21
SN-CONF errors and alarms are generated for two typ es of failures:
1. Failure of a board in the switch node c arrier to insert (be detected by
software).
2. A problem found b y running the Configuration Audit (tes t #759). Test 759
is executed for either an SNI or SNC circuit p ack during sch eduled
maintenance or as part of the test board UUCSS s command.
For SNI circuit packs, test 759 q ueries the SNI for SNCs in the same
switch node carrier, SNI peers, DS1 CONVs, and EI or SNI neighbors that
the SNI can communicate with and compares this data to the
administered data.
For SNC circuit packs, test 759 queries the SNC for SNCs and SNIs in the
same switch node carrier that the SNC can communicate with and
compares this data to the ad ministered data.
Switch node carriers are part of p ort network connectivity (PNC). For backg round
information about PNC, refer to the Maintenance Arch itecture and Hardware
Configurations chapters a nd related maintenance objec ts.

1. UU is the universal cabinet numb er (1 for PPN, 2 — 44 for EPNs). C is the carrier
designation (A, B, C, D, or E). SS is the number of the slot in which the c ircuit pack
resides (01 to 21). pp is the two d igit port number (01, 02, ...).

2. If the error and alarm logs display the switch node carrier location UUC, (c abinet and
carrier only), run the
long
test sequence on the active SNC in the carrier, (slot 10 or 12). If
the error and alarm logs display a circuit pac k location, UUCSS, run the
short
test
sequence on the alarmed SNI.
