Alarms in Linux Media Servers
Issue 1 June 2005 49
Back to: Hardware MOs Server-related alarms
DAJ1/DAL1 (Duplication Memory Board)
S8700 | 8710 only
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:
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:
Note: This call-status data is separate from the translations and Linux files shadowed
between servers. (See FSY (File Synchronization)
on page 67.)

MIN 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.
