BPX Switch Common Core Components
The Cisco WAN Manager NMS is connected to the LAN port on the BCC backcards. When control is
provided via an Ethernet interface, you configure the node IP address by using the cnflan command for
the BPX switch. For redundancy, also configure the LAN ports on both BCC back cards, each connected
to an AUI adapter.
The LAN port of the primary Broadband Control Card is active. If the secondary Broadband Control
Card becomes primary (active), then its LAN port becomes active. The Cisco WAN Manager
workstation will automatically try to restore communications over the LAN and will interface with the
newly active Broadband Controller Card.
For small networks, one Cisco WAN Manager workstation is adequate to collect statistics and provide
network management. For larger networks additional Cisco WAN Manager workstations may be
required. Refer to the Cisco WAN Manager Operations Guide.

Alarm/Status Monitor Card

The Alarm/Status Monitor (ASM) card is a front card. Only one is required per node and it is installed
in slot 15 of the BPX switch. It is used in conjunction with an associated back card, the Line Module
for the ASM (LM-ASM) card.
The ASM and LM-ASM cards are non-critical cards used for monitoring the operation of the node and
not directly involved in system operation. Therefore, there is no provision or requirement for card
redundancy.

Features

The ASM card provides a number of support functions for the BPX switch:

Functional Description

BPX switch system software commands the ASM card to activate the major and minor alarm indicators
and relays.
There are four significant circuits controlled by the ASM processor:
Release 9.3.0, Part Number 78-10674-01 Rev. D0, July 2001
Telco compatible alarm indicators, controls, and relay outputs.
Node power monitoring (including provision for optional external power supplies).
Monitoring of shelf cooling fans.
Monitoring of shelf ambient temperature.
Sensing for the presence of other cards that are installed in the BPX switch.
Alarm
The alarm monitor controls the operation of the front panel alarm LEDs and ACO and history
pushbuttons as well as the alarm relays that provide dry contact closures for alarm outputs to
customer connections.
Power supply monitor
The power supply monitor circuit monitors the status of the -48V input to the shelf on each of the
two power buses, A and B. The status of both the A bus and B power bus is displayed on the ASM
front panel.
