11.5 Network status LEDs
The interface board includes network status LEDs to help in troubleshooting network
connectivity and communication problems. These LEDs are located next to each network
connector in the rear of the patient monitor.
Standard Interface Board
The Standard Interface Board has 2 indicator LEDs for the MC connector:
•
The Link LED is lit, when the patient monitor is physically connected to a network.
• The Activity LED is lit when the patient monitor is either transmitting or receiving data
packets over the network.
Advanced Interface Board
The Advanced Interface Board has one dual purpose indicator LED for each network
connector:
•
The LED is lit to indicate a Link, i.e., the patient monitor is physically connected to a
network.
ACDC (green) The green ACDC LED should be lit when the patient monitor is
connected to the AC mains, even if the patient monitor is in standby
mode. A lit LED indicates that the DC/DC board receives the 15.3-16
VDC from the AC/DC power supply unit.
If the ACDC LED is not lit when the patient monitor is connected to live
AC mains, check the patient monitor for one of the problems:
•
Main fuses are blown.
•
DC/DC cable is disconnected from DC/DC board.
•
Faulty AC/DC power supply unit (especially, if the patient monitor operates
normally when it is battery powered).
•
Faulty DC/DC board (especially if the patient monitor does not operate
neither on AC mains nor battery power).
+ 12 V (yellow) These secondary voltages are created by the DC/DC board and they
should be lit when the patient monitor is turned On and operates
normally.
If one of the secondary voltages is not present (LED not lit) when the
patient monitor is turned on with the on/standby button, the DC/DC
board is most likely faulty.
+ 15 VMOD (green)
+ 5 V (green)
+ 3.3 V (yellow)
