Dräger Zeus Infinity Empowered Instructions For Use Manual page 437

– This device exchanges data with other medical
devices over the LAN network. The network
must support the following transmissions and
protocols:
– TCP/IP
– Unicast (static or dynamic addressing with
the ARP or RARP network protocols)
– Multicast
– Broadcast
– IGMP (Version 2)
This device can join or leave an IP multicast
group by using the IGMP network protocol.
Serial ports
This device supports the following ports:
– RS232 ports conforming to EIA RS232
(CCITT V.24/V.28) for the following applica-
tions:
– MEDIBUS, MEDIBUS.X
– Paging systems
– Connections to medical devices from other
manufacturers
– Ports based on USB 1.1 or USB 2.0 (e.g.,
mouse, keyboard, hard disk, USB stick,
CD drive)
Consequences of using an unsuitable network
If the network does not have the required charac-
teristics, hazardous situations can result. The fol-
lowing 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 connec-
tion:
– Alarms are not transmitted.
Instructions for use Zeus Infinity Empowered SW 2.n
– Without firewall and antivirus software:
– Data are not protected.
– Device settings are changed.
– The device generates false alarms or no
alarms.
– Data are sent incomplete, sent to the wrong de-
vice, or not sent at all.
– Patient data are intercepted, falsified, or dam-
aged.
– Data have incorrect time stamps.
– An overload of the device due to very high net-
work loading (e.g., caused by denial-of-service
attacks) can lead to deactivation of the inter-
face. The interface will only be available again
after the device has been restarted. In rare
cases, a warm boot may take place and may oc-
cur repeatedly.
Requirements for the electrical characteristics
of connected devices and networks
The LAN ports and the serial ports are only suitable
for connection of devices or networks that have a
nominal voltage of at most 24 V
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): Exposed sec-
ondary circuits
