This MO supports each S8700 media server’s Duplication Memory board (DAJ1) and the S8710 
media server’s Duplication Memory board (DAL1). These Duplication Memory boards are a NIC 
(network interface card) serving as the physical and data-link interface for an Ethernet-based 
duplication link between the servers. This link provides a call-status data path for sending:

●

TCP-based communication between each server’s Process Manager

●

UDP-based communication between each server’s Arbiter to:

- Enable arbitration between the active and standby servers

- Provide status signaling for memory refreshes

Note:

The Duplication Memory cards are not interchangeable between media servers. 
The DAJ1 will only work in S8700 media servers and the DAL1 will only work in 
S8710 media servers.

Note:

This call-status data is separate from the translations and Linux files shadowed 
between servers. (See

If the servers did not interchange, use the following procedure:

8. See if the standby server is busied-out, either from the:

- Web interface, by selecting View Summary Status

- Linux command line, by entering server

9. If so, release the standby server, either from the:

- Web interface, by selecting Release Server

- Linux command line, by entering server -r

If not, escalate this problem for explicit guidance with general 
troubleshooting of both servers.
