Server Alarms
DAJ1/DAL1/DAL2 (Duplication Memory Board)
The 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 boards are not interchangeable between servers:
The DAJ1 (256 MB) will only work with S8700-series servers.
The DAL1 (256 MB) will only work with S8710 and S8720 Servers with standard
configuration.
The DAL2 (512 MB) will only work with:
- S8730 Servers configured for hardware duplication (factory installed)
- S8720 Servers configured for hardware duplication running Communication Manager
4.0 and later
- S8710 Servers configured for hardware duplication running Communication Manager
5.0 and later
Table 6: DAJ1/DAL1/DAL2 Alarms describes Duplication Memory board alarms and their
troubleshooting procedures. See also ARB (Arbiter), DUP (Duplication Manager), and NIC
(Network Interface Card).
The Linux command testdupboard tests the Duplication Memory Board. This command
provides the ability to perform a local loop test and to read error registers. The local loop test
can only be run on a busied out standby server. To check the status of the servers, use the
server command. Enter man server to get information on how to busy out a server.
See testdupboard for the command usage and possible errors.

Level
Alarm Text, Cause/Description, Recommendation
1 MAJ "Single bit EDC test (bad err register)" - one or more single bit errors have
been detected and corrected on an SDRAM operation. The board
automatically corrects these errors. If this condition continues to occur,
replace the Duplication Memory board.
