Dräger Perseus A500 Instructions For Use Manual page 235

VLAN networks
If data is exchanged within a single physical
network and a clinical information system is being
used, an independent VLAN network must be set
up for the information system. Furthermore, at
least one of the following independent VLAN
networks must be set up:
– Network for medical devices for intrahospital
use
– Network for portable patient monitors
Serial ports
The following interfaces are supported:
– RS232 interfaces conforming to EIA RS-232
(CCITT V.24/V.28) for the following
applications
– MEDIBUS.X
– Interfaces based on USB 1.1 (e.g., USB flash
drive)
Consequences of using an unsuitable network
If the network does not meet the requirements,
hazardous situations can result. The following
situations can occur with this device:
– Due to an insecure decentralized alarm
system:
– Alarms are not transmitted.
– Alarms or data are transmitted with a delay.
– False alarms are triggered.
– During an interruption of the network
connection:
– Alarms are not transmitted.
– Suppressed alarms or alarm tones are not
reactivated, but remain suppressed.
Instructions for use Perseus A500 SW 1.1n
– Without firewall and antivirus software:
– Data are not protected.
– Device settings are changed.
– Data are sent incomplete, sent to the wrong
device, or not sent at all.
– Patient data are intercepted, falsified, or
damaged.
– Data have incorrect time stamps.
– An overload of the device due to very high
network loading (e.g., caused by denial-of-
service attacks) can lead to deactivation of the
interface. The interface will only be available
again after the device has been restarted. In
rare cases, a warm boot may take place and
may occur repeatedly.
Requirements for the electrical characteristics
The LAN interfaces and the serial interfaces are
only suitable for connection of devices or networks
that have a nominal voltage of at most 24 V DC on
the network side and that meet the requirements of
one of the following standards:
– IEC 60950-1: Ungrounded SELV circuits
– IEC 60601-1 (as of 2nd edition): Touchable
secondary circuits
