Symptom Possible Cause Recommended Measures
The SSID, IP address obtaining mode and
safe mode are not properly configured on
the patient monitor.
Reconfigure the information as instructed in this manual.
The patient monitor fails. Check if another patient monitor can be connected online. If yes,
restart this patient monitor and ensure that the two patient
monitors have the same configuration. If this patient monitor still
cannot be connected online, return it to Mindray for repair.
The patient monitor can
be connected to the AP,
but it cannot be
connected to the central
monitoring system.
The patient monitor has not obtained the
access permission of the central
monitoring system.
Allow the patient monitor to access the central monitoring
system.
The patient monitor cannot obtain an IP
address, and the IP addresses in the IP
address pool on the DHCP server have
been used up.
Connect another network device to the central monitoring
system, and check if the IP address can be obtained.
If you cannot address this problem, contact the IT department.
Static IP addresses conflict. Check if the patient monitor displays a message about an IP
address conflict.
If yes, ensure that each network device has a unique IP address.
The network link fails. Check if the central monitoring system can be pinged through
after the PC or mobile phone is connected to the AP.
If you cannot address this problem, contact the IT department.
The service port required by the patient
monitor is not enabled on the hospital
network.
Check if the service port required by the patient monitor has
been enabled on the hospital network. If no, enable the related
services (such as some UDP ports and multicast).
If you cannot address this problem, contact the IT department.
A single patient monitor
is disconnected
intermittently.
The patient monitor is moved outside the
coverage area.
Determine the position of disconnection, and check if the Wi-Fi
signal strength is greater than –65 dBm.
The patient monitor fails. Check if the patient monitor is easily disconnected at the same
position. If this problem persists after the patient monitor is
restarted, return this patient monitor to Mindray for repair.
Static IP addresses conflict. Check if the patient monitor displays a message about an IP
address conflict.
Check if an IP address is assigned to multiple devices.
Multiple patient monitors
are disconnected
intermittently.
The APs in some areas are damaged. Ensure that the APs have been turned on and operate properly.
There is strong interference in some areas. Use the network survey tool to check if the interference is strong.
Remove obvious interference sources or adjust the WLAN
deployment to meet the requirements of Mindray.
Signal coverage is insufficient in some
areas.
Use the network survey tool to check the signal coverage. If the
signal coverage is insufficient in a certain area, adjust the location
of the AP or add APs.
All the patient monitors
are disconnected
intermittently.
The wired network is not configured
properly.
Use the wired patient monitor to check the wired network
configuration. Ensure that the WLAN bandwidth configured on
the switch is sufficient, with a 50% surplus.
