Cisco BPX 8600 Series Installation and Configuration

Chapter 3 BPX Switch Common Core Components
Alarm/Status Monitor Card
The Cisco WAN Manager NMS is connected to the LAN port on the BCC back cards. When control is
provided through 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 BCC is active. If the secondary BCC becomes primary (active), then its
LAN port becomes active. The Cisco WAN Manager workstation will automatically try to restore
communications over the LAN and interfaces with the newly active BCC.
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 is required. For
more information, refer to the
Cisco WAN Manager User’s 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 noncritical 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 the following support functions for the BPX switch:
• 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.
Functional Description
BPX switch system software commands the ASM card to activate the major and minor alarm indicators
and relays.
The following are the four significant circuits controlled by the ASM processor:
•
Alarm—Controls the operation of the front panel alarm LEDs and ACO and history push buttons as
well as the alarm relays that provide dry contact closures for alarm outputs to customer connections.
•
Power supply monitor—Monitors the circuit monitors for 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.
