SDN Connectivity The first step is to investigate SDN connectivity -- are real-time patient monitoring
data flowing from patient monitors connected to the SDN to Information Centers?
Each SDN/Information Center connection should be checked to determine if patient
monitoring data are correctly being received and displayed.
Figure 7-3 SDN Connectivity Investigation
The following table provides a brief guideline for identifying sources of SDN
connectivity problems.
Caution Status Log information on a device that is disconnected from the network (e.g.
gone into local database mode) may not reflect the current status of other
devices on the Network.

Assessment Investigation
Are patient data (waveforms and parameters)
from the SCC being properly displayed on
the Information Center?
- Check Patient Sectors for each

Are all devices operational? - Check status LEDs on each device
Are all devices connected? - Check Status Log (See Caution)
Is the SDN interface operating correctly? - Check IC SDN interface card LEDs
