11.8.7 CARESCAPE Network communication issues

Traffic types
Two main types of communication occurs in the CARESCAPE Network: Broadcast and Unicast.
• Broadcast traffic is sent from one device to all devices on the network. Examples of
CARESCAPE broadcast traffic are device discovery, alarms, and time synchronization.
• Unicast traffic is sent from one device to another specific device on the network. An
example of CARESCAPE unicast traffic is patient waveforms.
Flow
• Upstream broadcast: The patient monitor sends broadcasts to other network devices.
• Downstream broadcast: The patient monitor receives broadcasts from other network
devices.
Recommended action
Check that the hinge flex board is intact and properly mounted to the CPU
board and to the module frame flex board.
Check the status of the VSYS RACK and VSYS ePort, see section
Hardware statistics.
If the VSYS RACK and VSYS ePort voltage is out of spec, but the VSYS exists
in the DC/DC board, the problem is most likely in the module frame flex
board.
The Ethernet communication for the PDM module is managed by the CPU
board.
Check PDM Log for possible PDM errors messages, see section "11.3.4".
If the cause is none of the above, the problem is most likely in the CPU
board. Replace the CPU board.
