Safety Information

This section describes the safety precautions that should be followed when installing and
operating the EDS-MD.

Warning:

 This equipment is not suitable for use in the presence of a flammable anesthetic

mixture including air, oxygen or nitrous oxide. To avoid the risk of electric
shock, this equipment must only be connected to a supply mains with
protective earth.

 The EDS-MD is not to be used in life support or as a life sustaining product.
 No modification of this equipment is allowed.

Cover

Warning: Do not remove the cover of the EDS-MD device server. There are no

user-serviceable parts inside. Opening or removing the cover may
expose you to dangerous voltage that could cause fire or electric shock.
Do not operate the EDS-MD if the housing is broken.

1: Using This Guide

Note: Refer all servicing to Lantronix.

Power Plug

 When disconnecting the power cord from the socket, pull on the plug, not the cord.

 Always connect the power cord to a properly wired and grounded power source. Do not use

adapter plugs or remove the grounding prong from the cord.

 Only use a power cord with a voltage and current rating greater than the voltage and current

rating marked on the unit.

 The appliance inlet serves as the main supply disconnect. Do not position the EDS-MD in

such a way that it is difficult to the disconnect EDS-MD.

Note:

 Install the unit near an AC outlet that is easily accessible.

 Always connect any equipment used with the product to properly wired and grounded power

sources.

 To help protect the product from sudden, transient increases and decreases in electrical

power, use a surge suppressor, line conditioner, or uninterruptible power supply (UPS).

 Do not connect or disconnect this product during an electrical storm.

Input Supply

 Check nameplate ratings to assure there is no overloading of supply circuits that could affect

over current protection and supply wiring.

EDS-MD® Medical Device Server User Guide 14

1: Using This Guide

Grounding

 Maintain reliable grounding of this product.

 Pay particular attention to supply connections when connecting to power strips, rather than

directly to the branch circuit.

Fuses

There are fuses on the internal power supply serviceable only by Lantronix.

Battery

A Lithium battery cell inside the unit maintains the unit's date and time when the device is powered
off. Do not attempt to replace it. The battery is serviceable only by Lantronix.

Caution: DANGER OF EXPLOSION IF BATTERY IS INCORRECTLY REPLACED.

REPLACE ONLY WITH THE SAME OR EQUIVALENT TYPE
RECOMMENDED BY THE MANUFACTURER. DISPOSE OF USED
BATTERIES ACCORDING TO THE MANUFACTURER'S INSTRUCTIONS.

Attention

IL Y A DANGER D'EXPLOSION S'IL Y A REMPLACEMENT INCORRECT
DE LA BATTERIE, REMPLACER UNIQUEMENT AVEC UNE BATTERIE
DU MÊME TYPE OU D'UN TYPE ÉQUIVALENT RECOMMANDÉ PAR LE
CONSTRUCTEUR. METTRE AU REBUT LES BATTERIES USAGÉES
CONFORMÉMENT AUX INSTRUCTIONS DU FABRICANT.

Wall Mounting

If wall-mounted units are installed, the following items must be considered:

 Do not install the unit in such a way that a hazardous stability condition results because of

uneven loading. A drop or fall could cause injury.

 Make sure to install the EDS-MD unit in an environment with an ambient temperature less

than the maximum operating temperature of the EDS-MD device. Therefore, consideration
should be given to installing the equipment in an environment compatible with the maximum
ambient temperature (Tma) specified by the manufacturer.

 Maintain reliable earthing of wall-mounted equipment. Give particular attention to supply

connections other than direct connections to the branch circuit (e.g. use of power strips)
because of the effect that overloading of the circuits might have on overcurrent protection and
supply wiring. Appropriate consideration of equipment nameplate ratings should be used
when addressing this concern.

Note: Before operating the EDS-MD device, make sure the device mounting is secured.

Port Connections

 Only connect the network port to an Ethernet network that supports 10 Base-T/100 Base-TX/

1000 Base-T.

 Only connect device ports to equipment with serial ports that support EIA-232 (formerly RS-

232C). Unless specified otherwise, only connect USB ports to USB thumb drives.

EDS-MD® Medical Device Server User Guide 15

1: Using This Guide

Warning: To avoid overloading and overheating, do not use a USB port as a

charger port or a power port for other devices such as a cellular phone,
PDA device, disk drive, etc.

WARNINGS OF NETWORK CONNECTIONS

The integration of the EDS-MD medical device server into an IT network may constitute a Medical
Electrical (ME) System. It is recommended that the system leakage current be measured to verify
that the basic requirement for the safety of the ME System, after installation or subsequent
modification of the system, does not result in an unacceptable risk.

The integration of the EDS-MD into a IT network may result in unforeseen risks associated with
the interconnection of the EDS-MD Programmable Electronic Subsystem (PESS)/Programmable
Electrical Medical Systems (PEMS) to IT Networks. Connection of equipment containing PEMS to
an IT NETWORK/DATA COUPLING that includes other equipment could result in previously
unidentified risks to patients, operators or third parties. The entity accountable for the use and
maintenance of an ME EQUIPMENT or an ME SYSTEM should identify, analyze, evaluate and
control these RISKS. Subsequent changes to the IT NETWORK/DATA COUPLING could
introduce new RISKS and require additional analysis. Changes to the IT NETWORK/DATA
COUPLING include:

 Changes in NETWORK/DATA COUPLING configuration

 Connection of additional items to the IT NETWORK/DATA COUPLING

 Disconnecting items from the IT NETWORK/DATA COUPLING

 Update of equipment connected to the IT NETWORK/DATA COUPLING

 Upgrade of equipment connected to the IT NETWORK/DATA COUPLING

Equipment Classifications

 Classification according to the type of protection against electric shock: Class I Equipment

 Classification according to the degree of protection against electric shock: No Applied Parts

 Classification according to the degree of protection against ingress of water: IP20

 Classification according to the mode of operation: Continuous Operation

Environmental Conditions for Transportation and Storage

 An ambient temperature range of -30°C to +80°C

 A relative humidity range of 0% to 95%, noncondensing

 An atmospheric pressure range of 50 kPa to 106 kPa

Cleaning Instructions

1. Disconnect all cables and unplug AC power cord from the device.

2. Prepare a disinfectant solution using 1 part bleach mixed with 9 parts water.

3. Lightly moisten a tissue with the mild detergent and wipe down only the outside of the device.

4. Allow the device to air-dry or wipe dry with a clean dry tissue before use.

Caution: To avoid electric shock and for the device to work properly, do not allow

cleaning solution to get inside the device, specifically the interface port
connectors or the power inlet. Do not immerse the device in any liquid.

logging into the EDS-MD 4/8/16 device server and assigning IP addresses and other configurable
settings:

2: Introduction

 Web Manager: View and configure all settings easily through a web browser using the

Lantronix Web Manager. (See Configuration Using Web Manager on page 33.)

 DeviceInstaller: Configure the IP address and related settings and view current settings on

the EDS-MD 4/8/16 device server using a Graphical User Interface (GUI) on a PC attached to
a network. You will need the latest version of the Lantronix® DeviceInstaller™ utility. (See

Accessing the PremierWave XC HSPA+ Device Using DeviceInstaller on page 30.)

 Command Mode: There are a few methods for accessing Command Mode (CLI): making a

Telnet connection, or connecting a PC or other host running a terminal emulation program to
the unit’s port. (See the EDS-MD Medical Device Server Command Reference for instructions
and available commands.)

 XML: The EDS-MD 4/8/16 device server supports XML-based configuration and setup

records that make device configuration transparent to users and administrators. XML is easily
editable with a standard text or XML editor. (See the EDS-MD Medical Device Server
Command Reference for instructions and commands).

Addresses and Port Numbers

Hardware Address

The hardware address is also referred to as the Ethernet address, physical address, or MAC
address. The first three bytes of the Ethernet address are fixed and identify the unit as a Lantronix
product. The fourth, fifth, and sixth bytes are unique numbers assigned to each unit. Sample
hardware address:

 00-20-4A-14-1B-18

 00:20:4A:14:1B:18

EDS-MD® Medical Device Server User Guide 19

2: Introduction

IP Address

Every device connected to an IP network must have a unique IP address. This address references
the specific unit.

Port Numbers

Every TCP connection and every UDP datagram is defined by a destination and source IP
address, and a destination and source port number. For example, a Telnet server commonly uses
TCP port number 23.

The following is a list of the default server port numbers running on the EDS-MD 4/8/16 device
server:

 TCP Port 23: Telnet Server (Command Mode configuration)

 TCP Port 80: HTTP (Web Manager Configuration)

 TCP Port 21: FTP

 UDP Port 30718: LDP (Lantronix Discovery Protocol) port

 TCP/UDP Port 10001: Tunnel 1 (see note below)

Note: Additional TCP/UDP ports and tunnels will be available, depending on the product

type. The default numbering of each additional TCP/UDP port and corresponding tunnel
will increase sequentially (i.e., TCP/UDP Port 1000X: Tunnel X).

Accept Mode

In Accept Mode, the EDS-MD device listens (waits) for incoming connections from the network. A
remote node on the network initiates the connection.

The configurable local port is the port the remote device connects to for this connection. There is
no remote port or address. Supported serial lines and associated local port numbers progress
sequentially in matching value. For instance, the default local port is 10001 for serial line 1 and the
default local port for serial line 2 is 10002, and so on for the number of serial lines supported.

Serial data can still be received while waiting for a network connection, keeping in mind serial data

Connect Mode

In Connect Mode, the EDS-MD unit continues to attempt an outgoing connection on the network,
until established (based on which connection method is selected in the configuration described in

Table 7-6). If the connection attempt fails or the connection drops, then it retries after a timeout.

The remote node on the network must listen for the Connect Mode’s connection.

For Connect Mode to function, it must be enabled, have a remote station (node) configured, and a
remote port configured (TCP or UDP). When established, Connect Mode is always on. Enter the
remote station as an IPvor IP address or DNS name. The EDS-MD device will not make a
connection unless it can resolve the address.

For Connect Mode using UDP, the EDS-MD module accepts packets from any device on the
network. It will send packets to the last device that sent it packets.

Note: The port in Connect Mode is not the same port configured in Accept Mode.

The TCP keepalive time is the time in which probes are periodically sent to the other end of the
connection. This ensures the other side is still connected.

Text or Binary form.

Notes:

 If the keep alive idle time (the initial keep alive probe) expires, the user

timeout is expired, and there are probes in flight, the connection will be
reset. For this reason, it is recommended that if keep alive is used in
conjunction with the user timeout, the keep alive timeouts be larger than
the user timeout. If they are smaller, what will typically be seen is that the
initial probe will be sent, then at the interval where the next probe would
normally be sent, the connection will be reset, with no additional probes
sent. Also note that the probe count can be disregarded in these cases: if
the keep alive timers are significantly smaller than the user timeout, probes
will continue to be sent for an unreachable host until the user timeout
expires.

 If there is data in flight when the TCP retransmission timeout kicks in, the

user timeout is checked as a limiting condition only when the timer
expirations would normally be checked during RTO handling. In other
words, the user timeout will not be an exact limit; in practice, it will always
take somewhat longer for the connection to be closed. The longer the user
timeout is, the more likely it will expire between exponentially slower
retransmissions, and the connection will not experience an error until the
next retransmission timeout is checked. Also note that the user timeout
expiration during retransmission returns an error to the application; it does
not automatically reset the connection as happens with keep alive timeout.
It is up to the application (e.g., tunneling) to close the connection (this
happens almost immediately with tunneling).

Set the value of the reconnect timeout (in milliseconds) for outgoing connections
established by the device. Valid range is 1 to 65535 milliseconds. Default is

15000.

Set whether the serial Line data buffer is flushed upon a new network

Connecting Multiple Hosts

If more than one host is configured, a Host Mode option appears. Host Mode controls how
multiple hosts will be accessed. For the EDS-MD device, the Connect Mode supports up to 32
hosts. Hosts may be accessed sequentially or simultaneously:

 Sequential – Sequential host lists establish a prioritized list of tunnels. The host specified as

Host 1 will be attempted first. If that fails, it will proceed to Host 2, 3, etc, in the order they are
specified. When a connection drops, the cycle starts again with Host 1 and proceeds in order.
Establishing the host order is accomplished with host list promotion (see Host List Promotion

on page 56). Sequential is the default Host Mode.

 Simultaneous – A tunnel will connect to all hosts accepting a connection. Simultaneous

connections occur at the same time to all listed hosts. The device can support a maximum of
64 total aggregate connections.

10: Security Settings

The EDS-MD device supports Secure Shell (SSH) and Secure Sockets Layer (SSL). SSH is a
network protocol for securely accessing a remote device. SSH provides a secure, encrypted
communication channel between two hosts over a network. It provides authentication and
message integrity services.

Secure Sockets Layer (SSL) is a protocol that manages data transmission security over the
Internet. It uses digital certificates for authentication and cryptography against eavesdropping and
tampering. It provides encryption and message integrity services. SSL is widely used for secure
communication to a web server. SSL uses certificates and private keys.

Note: The device supports SSLv3 and its successors, TLS1.0 and TLS1.1. An incoming

SSLv2 connection attempt is answered with an SSLv3 response. If the initiator also
supports SSLv3, SSLv3 handles the rest of the connection.

Public Key Infrastructure

Public key infrastructure (PKI) is based on an encryption technique that uses two keys: a public
key and private key. Public keys can be used to encrypt messages which can only be decrypted
using the private key. This technique is referred to as asymmetric encryption, as opposed to
symmetric encryption, in which a single secret key is used by both parties.

TLS (SSL)

Transport Layer Security (TLS) and its predecessor, Secure Sockets Layer (SSL), use asymmetric
encryption for authentication. In some scenarios, only a server needs to be authenticated, in
others both client and server authenticate each other. Once authentication is established, clients
and servers use asymmetric encryption to exchange a secret key. Communication then proceeds
with symmetric encryption, using this key.

SSH and some authentication methods on the EDS-MD device servers make use of SSL. The
EDS-MD 4/8/16 unit supports SSLv2, SSLv3, and TLS1.0.

TLS/SSL application hosts use separate digital certificates as a basis for authentication in both
directions: to prove their own identity to the other party, and to verify the identity of the other party.
In proving its own authenticity, the EDS-MD device servers will use its own "personal" certificate.
In verifying the authenticity of the other party, the EDS-MD devices will use a "trusted authority"
certificate.

In short:

 When using EAP-TLS, the EDS-MD device server needs a personal certificate with matching

private key to identify itself and sign its messages.

 When using EAP-TLS, EAP-TTLS or PEAP, the EDS-MD unit needs the authority certificate(s)

that can authenticate those it wishes to communicate with.

EDS-MD® Medical Device Server User Guide 69

Digital Certificates

The goal of a certificate is to authenticate its sender. It is analogous to a paper document that
contains personal identification information and is signed by an authority, for example a notary or
government agency. With digital certificates, a cryptographic key is used to create a unique digital
signature.

Trusted Authorities

A private key is used by a trusted certificate authority (CA) to create a unique digital signature.
Along with this private key is a certificate of authority, containing a matching public key that can be
used to verify the authority's signature but not re-create it.

A chain of signed certificates, anchored by a root CA, can be used to establish a sender's
authenticity. Each link in the chain is certified by a signed certificate from the previous link, with
the exception of the root CA. This way, trust is transferred along the chain, from the root CA
through any number of intermediate authorities, ultimately to the agent that needs to prove its
authenticity.

10: Security Settings

Obtaining Certificates

Signed certificates are typically obtained from well-known CAs, such as VeriSign, Inc. This is
done by submitting a certificate request for a CA, typically for a fee. The CA will sign the certificate
request, producing a certificate/key combo: the certificate contains the identity of the owner and
the public key, and the private key is available separately for use by the owner.

As an alternative to acquiring a signed certificate from a CA, you can act as your own CA and
create self-signed certificates. This is often done for testing scenarios, and sometimes for closed
environments where the expense of a CA-signed root certificate is not necessary.

Self-Signed Certificates

A few utilities exist to generate self-signed certificates or sign certificate requests. The EDS-MD
device servers also have the ability to generate its own self-signed certificate/key combo. You can
use XML to export the certificate in PEM format, but you cannot export the key. Hence, the internal
certificate generator can only be used for certificates that are to identify that particular EDS-MD
module.

Certificate Formats

Certificates and private keys can be stored in several file formats. Best known are PKCS12, DER
and PEM. Certificate and key can be in the same file or in separate files. Additionally, the key can
be either be encrypted with a password or left in the clear. However, EDS-MD device servers
currently only accepts separate PEM files, with the key unencrypted.

Several utilities exist to convert between the formats.

EDS-MD® Medical Device Server User Guide 70

OpenSSL

OpenSSL is a widely used open source set of SSL related command line utilities. It can act as
server or client. It can also generate or sign certificate requests, and can convert from and to
several different of formats.

OpenSSL is available in binary form for Linux and Windows.

To generate a self-signed RSA certificate/key combo:

openssl req -x509 -nodes -days 365 -newkey rsa:1024 -keyout mp_key.pem ­out mp_cert.pem

10: Security Settings

See www.openssl.org

Note: Signing other certificate requests is also possible with OpenSSL but the details of

this process are outside the scope of this document.

Steel Belted RADIUS

Steel Belted RADIUS is a commercial RADIUS server from Juniper Networks that provides a GUI
administration interface. It also provides a certificate request and self-signed certificate generator.

The self-signed certificate has extension .sbrpvk and is in the PKCS12 format. OpenSSL can
convert this into a PEM format certificate and key:

openssl pkcs12 -in sbr_certkey.sbrpvk -nodes -out sbr_certkey.pem

The sbr_certkey.pem file contains both certificate and key. If loading the SBR certificate into an
EDS-MD device server as an authority, you will need to edit it:

1. Open the file in any plain text editor.

2. Delete all info before "----- BEGIN CERTIFICATE-----" and after "----- END

CERTIFICATE-----", and then save as sbr_cert.pem.

SBR accepts trusted-root certificates in the DER format. Again, OpenSSL can convert any format
into DER:

or www.madboa.com/geek/openssl for more information.

openssl x509 -inform pem -in mp_cert.pem -outform der -out mp_cert.der

Note: With SBR, when the identity information includes special characters such as

dashes and periods, SBR changes the format it uses to store these strings and becomes
incompatible with the current EDS-MD device server release. Support may be added for
this and other formats in future releases.

Free RADIUS

Note: Free RADIUS is another versatile Linux open-source RADIUS server.

SSH Settings

SSH is a network protocol for securely accessing a remote device over an encrypted channel. This
protocol manages the security of internet data transmission between two hosts over a network by
providing encryption, authentication, and message integrity services.

Configuration is required when the EDS-MD device is either (1) the SSH server or (2) an SSH
client.. The SSH server is used by the CLI (Command Mode) and for tunneling in Accept Mode.
The SSH client is for tunneling in Connect Mode.

To configure the EDS-MD device server as an SSH server, there are two requirements:

 Defined Host Keys: both private and public keys are required. These keys are used for the

Diffie-Hellman key exchange (used for the underlying encryption protocol).

 Defined Users: these users are permitted to connect to the EDS-MD device SSH server.

SSH Server Host Keys

The SSH Server Host Keys are used by all applications that play the role of an SSH Server.
Specifically Tunneling in Accept Mode. These keys can be created elsewhere and uploaded to the

SSH Client Users

The SSH Client Users are used by all applications that play the role of an SSH Client. Specifically
Tunneling in Connect Mode. To configure the EDS-MD device server as an SSH client, an SSH
client user must be both configured and also exist on the remote SSH server.

At the very least, a Password or Key Pair must be configured for a user. The keys for public key
authentication can be created elsewhere and uploaded to the device or automatically generated
on the device.

If uploading existing Keys, take care to ensure the Private Key will not be compromised in transit.
This implies the data is uploaded over some kind of secure private network.

The default Remote Command is '<Default login shell>' which tells the SSH Server to execute a
remote shell upon connection. This can be changed to anything the SSH Server on the remote
host can execute.

14: Branding the EDS-MD Device

This chapter describes how to brand your EDS-MD device server by using Web Manager and
Command Line Interface (CLI). It contains the following sections on customization:

 Web Manager Customization

 Short and Long Name Customization

Web Manager Customization

Customize the Web Manager's appearance by modifying index.html, style.css, and the product
logo. The style (fonts, colors, and spacing) of the Web Manager is controlled with style.css. The
text and graphics are controlled with index.html. The product logo is the image in top-left corner of
the page and defaults to a product name image.

Note: The recommended dimensions of the new graphic are 300px width and 50px

height.

The Web Manager files are hidden and are incorporated directly into the firmware image but may
be overridden by placing the appropriate file in the appropriate directory on the EDS-MD 4/8/16
unit file system.

Web Manager files can be retrieved and overridden with the following procedure:

1. FTP to the EDS-MD 4/8/16 device.

2. Make a directory (mkdir) and name it http/config .

3. Change to the directory (cd) that you created in step 2 (http/config).

4. Save the contents of index.html and style.css by using a web browser and navigating to

http://<EDS-MD hostname>/config/index.html and http://<EDS-MD
hostname>/config/style.css.

5. Modify the file as required or create a new one with the same name.

6. To customize the product logo, save the image of your choice as logo.gif

7. Put the file(s) by using put <filename>.

8. Type quit. The overriding files appear in the file system's http/config directory.

9. Restart any open browser to view the changes.

10. If you wish to go back to the default files in the firmware image, simply delete the overriding
files from the file system.

EDS-MD® Medical Device Server User Guide 97

Short and Long Name Customization

You can customize the short and long names in your EDS-MD device server. The names display
in the CLI show command and in the System web page in the Current Configuration table. The
short name is used for the show command. Both names display in the CLI Product Type field.

Note: See System Settings (on page 88) for additional configuration options available

on the Systems page.

Appendix B: Binary to Hexadecimal Conversions

Many of the unit's configuration procedures require you to assemble a series of options
(represented as bits) into a complete command (represented as a byte).

The resulting binary value must be converted to a hexadecimal representation.

Use this chapter to learn to convert binary values to hexadecimals or to look up hexadecimal
values in the tables of configuration options. The tables include:

 Command Mode (serial string sign-on message)

 AES Keys

Converting Binary to Hexadecimal

Following are two simple ways to convert binary
numbers to hexadecimal notation.

Conversion Table

Hexadecimal digits have values ranging from 0 to F,
which are represented as 0-9, A (for 10), B (for 11),
etc. To convert a binary value (for example, 0100

1100) to a hexadecimal representation, treat the upper

and lower four bits separately to produce a two-digit
hexadecimal number (in this case, 4C). Use the
following table to convert values from binary to
hexadecimal.

Scientific Calculator

Another simple way to convert binary to hexadecimal
is to use a scientific calculator, such as the one
available on the Windows operating systems. For
example:

1. On the Windows Start menu, click Programs ->
Accessories -> Calculator.

2. On the View menu, select Scientific. The scientific
calculator appears.

3. Click Bin (Binary), and type the number you want
to convert.
