Diagnose the Problem
as SDN or
Non-SDN
Using the symptoms and information gathered in the previous steps,
diagnose and isolate the problem as a malfunction of a specific product or
a problem with the SDN system communication.
Some SDN and non-SDN product related symptoms are listed below.
Noisy Branch 1. Remove each RJ45 connector one at a time to determine which is the
noisy branch.
NO OVERVIEW FUNCTIONS
AVAILABLE Monitor/terminal is not connected to the
SDN, or it is getting no signals from the ACC;
i.e., it is operating in the Autopoll mode.
NO DATA FROM BEDS IN UNIT In this Care Unit there are no beds in the
same group as this bed and no beds in the All
Beds Care group.
NO DATA FROM BED A bed which was currently being viewed in
the OVERVIEW section of the screen has
stopped communicating on the SDN. The
message remains until the bed returns or
display is cleared with the CLEAR hard key or
until NEXTBED softkey is used to view
another bed.
Indicates discontinued or cut off data.
Displayed in sector(s) for which no data is
available—in inverse video. If the patient has
been moved or discharged, there are several
ways to clear this message.
Tune the sector to a different bed in the
system using SETUP and NEW BED keys. A
new bed label, waveform data, etc., will
appear if the new bed is active on the
network.
NO RECORDER AVAILABLE This message appears when either stored
waveform or real time waveform recordings
are requested if IC recorder is out of paper or
its door is open (IC message CHECK PAPER/
DOOR RECORDER #_____ or NO RECORDER
ON LINE). This message appears for any
record request (stored, real time, or delayed)
if the M/T is in the Autopoll mode or if there
is no primary monitoring IC for this bedside.
