• Primary machine identifier - Enter the MAC address of the primary BSC. In the
event of a failover, this entry is used to identify the primary BSC for the
administrator, because the rest of the configuration parameters are identical on
both primary and secondary.

Note: Click the This device link to automatically fill in the Primary machine identifier
field with the MAC address of the BSC to which you are connected.
3. Click Save to store the failover settings to the BSC database.
A BSC heartbeat is one to two seconds in duration, so using the default failover settings
of 3 failed beats and a heart beat interval of 5.0 seconds means that it would take
approximately 15-20 seconds before failover occurs.
Completing the Failover Setup
Before completing this procedure, ensure that:
• the primary BSC has been fully configured as desired and is powered up
• the secondary BSC is powered off
• you have the proper cable, a straight through cable for the BSC 1200 and an
Ethernet crossover cable for all other BSC models.
To complete the failover setup between the primary BSC and the secondary BSC:
1. Connect the Ethernet cable between the Failover port on the primary BSC and the
Failover port on the secondary BSC.
2. Power up the secondary BSC. The secondary BSC will download its configuration
from the primary BSC and then enter standby mode. No other configuration is
necessary on the secondary BSC.
)
Note: Occasionally, when the failover BSC is rebooting, you might see "Sync Failures"
messages on the LCD of the failover BSC. This message does not indicate a problem and
can be safely ignored, unless it persists for longer than five minutes, in which case you
should contact your Customer Service Representative.
Configuring Static Routes
The BSC automatically builds and maintains its own internal routing table to keep track of
gateway addresses and interfaces used to reach network and host destinations.
To display the BSC's internal routing table, click the Network tab in the administrator
console, and then click the Routing Table tab on the Network page. The BSC Routing
table appears as shown in Figure 4-21.
