Instruction Manual
Initial Conguration
Unpack the ECS0016 kit and verify you have all of the par ts indicated in the Package Contents list shown on the previous page, and that they all appear in good working order.
If you are installing your ECS0016 in a rack, you will need to attach the rack-mounting brackets supplied with the unit, and install the unit in the rack. Following this, proceed to connect your ECS0016 to the network, as well as to the serial ports of the controlled devices, and to an power outlet as outlined below.
Power Connection
The ECS0016 and CM4148 models have a built-in universal autoswitching AC power supply. This power supply accepts AC input voltage between 100 and 240 VAC with a frequency of 50 or 60 Hz and the power consumption is less than 20W.
AC power socket
The ECS0016 has an IEC AC power socket located at the rear of the metal case, which uses a conventional IEC AC power cord. The North American power cord is provided by default.
There is a warning notice printed on the back of each unit:

Instruction Manual
Management Console Connection
The ECS0016 is pre-configured with a default IP Address: 192.168.0.1 and Subnet Mask: 255.255.255.0 .
Directly connect a PC or workstation to the ECS0016. To configure the ECS0016 with a browser, the connected PC or workstation should have an IP address in the same range as the ECS0016 (e.g. 192.168.0.100)
Please note: For initial configuration, it is recommended that the ECS0016 be connected directly to a single PC or workstation. If you choose to connect your LAN before completing the initial setup steps:
Ensure there are • no other devices on the LAN with an IP Address of
192.168.0.1
Ensure the Console Server and the PC/workstation are on the • same
LAN segment, with no interposed router appliances
To configure the IP Address of your Linux or Unix PC/workstation simply run ipconfig. For Windows PCs (Win9x/Me/2000/XP/ NT):
Click 1. Start > Settings, then select Control Panel and double-click
Network Connections (for 95/98/Me, double click Network).
Right-click on 2. Local Area Connection and select Properties.
Select 3. Internet Protocol (TCP/IP) and click Properties.
Select 4. Use the following IP address and enter the following details:
IP address: 192.168.0.100 Subnet mask: 255.255.255.0.
If you wish to retain your existing IP settings for this network connection, click Advanced and add the above as a secondary IP connection.

Instruction Manual
ARPPing IP Address Assignment
If it is not convenient to change the PC/workstation network address, you can use the ARP-Ping command to reset the ECS0016 IP address. To do this from a Windows PC:
Click 1. Start > Run
Type 2. cmd in the text box provided and click OK to open the command
line
Type 3. arp –d to flush the ARP cache:
Type 4. arp –a to view the current ARP cache which should now be
empty.
Now, add a static entry to the ARP table and ping the ECS0016 to prompt it to assume the IP address.
The following example illustrates an ECS0016 with a MAC Address 00:13:C6:00:02:0F (designated on the label on the bottom of the unit), and we are setting its IP address to 192.168.100.23. Also, the PC/work station issuing the arp command must be on the same network segment as the ECS0016 (i.e. have an IP address of 192.168.100.xxx).
Type 5. arp -s 192.168.100.23 00-13-C6-00-02-0F (Note for UNIX the
syntax is: arp -s 192.168.100.23 00:13:C6:00:02:0F)
Type 6. ping -t 192.18.100.23 to start a continuous ping to the new IP
Address.
Turn on the ECS0016 and wait for it to configure itself with the new IP 7.
Address. It will start replying to the ping at this point.
Type 8. arp –d to flush the ARP cache again.
Activate your preferred browser on the connected PC/ workstation and 9.
enter https://192.168.0.1 in the URL field.
4
Instruction Manual
You will be prompted to log in. Enter the default administration username and administration password:
Username: root Password: default
Please note: The ECS0016 is factory configured with HTTP disabled and HTTPS enabled appliances
Please note: Note If you are not able to connect to the Management Console at 192.168.0.1 or if the default Username / Password were not accepted then reset your ECS0016
A Welcome screen will appear , listing the four basic installation configu­ration steps:
After completing each of the steps listed, you can return to the configura­tion list by clicking in the top left corner of the screen on the StarTech.com logo.
As you complete each step, the configuration list will be updated (e.g. after you have configured the serial ports it will display this step as Done.
5
Instruction Manual
Administrator Password
For security reasons, only the Administrator (the administration user named root) can initially log into your gateway; only those people who know the root password can access and reconfigure the ECS0016 gate­way itself.
As such, it is important that you enter and confirm a new password before giving the ECS0016 any access to, or control of, your computers and network appliances. To do so:
Select 1. System: Administration
Enter a new System Password then re-enter it in the field marked 2. confirm System Password. This is the new password for root, the main administrative user account, so it is important that you choose a complex password, and keep it safe.
(Optional)At this stage you may also wish to enter a 3. System Name and System Description for the ECS0016 gateway to give it a unique ID and make it simple to identify.
Click 4. Apply. As you have changed the password you will be prompted to log in again. This time use the new password.
6
Instruction Manual
Network IP address
You now must enter an IP address for the principal Ethernet (LAN/Net­work/Network1) port on the ECS0016 gateway, or enable its DHCP client so that it automatically obtains an IP address from a DHCP server on the network to which it is connected.
On the System: IP menu:
Select the 1. Network page then check DHCP or Static for the Configuration Method
If you selected 2. Static you must manually enter the new IP Address, Subnet Mask, Gateway and DNS server details. This selection automatically disables the DHCP client.
If you selected DHCP, the ECS0016 will look for configuration details 3. from a DHCP server on your management LAN. This selection automatically disables any static address. The ECS0016 MAC address can be found on a label on the base plate of the unit.
Please note: In its factory default state (with no Configuration Method selected) the ECS0016 has its DHCP client enabled, so it automatically accepts any network IP address assigned by a DHCP server on your net­work. In this initial state, the ECS0016 will then respond to both its Static address (192.168.0.1) and its newly assigned DHCP address.
7
Instruction Manual
By default the ECS0016 LAN port auto detects the Ethernet connection speed. However you can use the Media menu to lock the Ethernet to 10 Mb/s or 100Mb/s and to Full Duplex (FD) or Half Duplex (HD).
Please note: If you have changed the ECS0016 IP address, you may need to reconfigure your PC/workstation so it has an IP address that is in the same network range as this new address (as detailed in an earlier note in this chapter).
Click 4. Apply. You will need to reconnect the browser on the PC / workstation that is connected to the ECS0016, by entering http://new IP address .
System Services
The Administrator can access and configure the ECS0016 gateway using a range of access protocols. The factory default enables HTTPS and SSH access and disables HTTP and Telnet. The Administrator can simply dis­able any of the services, or enable others.
Select the System: Services option then select /deselect for the service to be enabled /disabled. The following access protocol options are avail­able:
8
Instruction Manual
HTTPS
This ensures secure browser access to all of the Management Console menus. It also allows appropriately configured Users secure browser ac­cess to selected Management Console Manage menus.
If you enable HTTPS, the Administrator will be able to use a secure browser connection to the ECS0016 gateway’s Management Console. By default HTTPS is enabled, and it is recommended that only HTTPS access be used if the gateway is to be managed over any public network (e.g. the Internet).
HTTP
The HTTP service allows the Administrator basic browser access to the Management Console. It is recommended that the HTTP service be disabled if the ECS0016 gateway is to be remotely accessed over the Internet.
Telnet
This gives the Administrator telnet access to the system command line shell (Linux commands). While this may be suitable for a local direct connection over a management LAN, it is recommended this service be disabled if the ECS0016 is to be remotely administered.
SSH
This service provides secure SSH access to the Linux command line shell. It is recommended you choose SSH as the protocol where the Ad­ministrator connects to the gateway over the Internet or any other public network. This will provide authenticated communications between the SSH client program on the remote PC/workstation and the SSH server in the gateway.
9
Instruction Manual
There are also a number of related service options that can be configured at this stage:
SNMP
This will enable netsnmp in the gateway, which will keep a remote log of all posted information. SNMP is disabled by default. To modify the default SNMP settings, the Administrator must make the edits at the command line.
Ping
This allows the ECS0016 to respond to incoming ICMP echo requests. Ping is enabled by default, however for security reasons this service should generally be disabled following initial configuration.
And there are some serial port access parameters that can be configured on this menu:
Base
The ECS0016 uses specific default ranges for the TCP/IP ports for the various access services that Users and Administrators can use to access devices attached to serial ports. The Administrator can also set alternate ranges for these services, and these secondary ports will then be used in addition to the defaults.
The default TCP/IP base port address for telnet access is 2000, and the range for telnet is IP Address: Port (2000 + serial port #) i.e. 2001 – 2048. If the Administrator were to set 8000 as a secondary base for telnet, serial port #2 on the gateway can be telnet accessed at IP Address:2002 and at IP Address:8002.
The default base for SSH is 3000; for Raw TCP is 4000; and for RFC2217, 5000.
Once you’ve made the appropriate selections, click Apply.
10
Instruction Manual
Communications Software
You have configured access protocols for the Administrator client to use when connecting to the ECS0016. User clients (who you may set up later) will also use these protocols when accessing ECS0016 serial attached devices and network attached hosts.
You will need to have appropriate communications software tools set up on the Administrator (and User) client’s PC/workstation. ECS0016 includes MetaConnect as the recommended client software tool, however other generic tools such as PuTTY and SSHTerm may be used, and these are all described below:
MetaConnect
StarTech.com recommends using the MetaConnect communications software tool for all communications with ECS0016 gateways, to ensure these communications are secure. Each ECS0016 is supplied with an unlimited number of MetaConnect licenses to use with that gateway.
MetaConnect is a lightweight tool that enables Users and Administrators to securely access the ECS0016 gateway, and the various computers, network devices and appliances that may be serially or network con­nected to the gateway.

11
Instruction Manual
MetaConnect is a Java client program that couples the SSH tunneling protocol with popular access tools such as Telnet, SSH, HTTP, HTTPS, VNC, RDP, to provide point-and-click secure remote management access to all the systems and devices being managed.
MetaConnect can be installed on Windows 2000, XP, 2003, Vista™ PCs and on most Linux, UNIX and Solaris configurations
PuTTY
Communications packages like PuTTY can be also used to connect to the ECS0016 gateway command line.
PuTTY is a freeware implementation of Telnet and SSH for Win32 and UNIX platforms, that runs as an executable application without needing to be installed onto your system. PuTTY (the Telnet and SSH client itself) can be downloaded at http://www.tucows.com/preview/195286
To use PuTTY for an SSH terminal session from a Windows client, you • enter the gateway’s IP address as the ‘Host Name (or IP address)
To access the ECS0016 command line you select ‘SSH’ as the • protocol, and use the default IP Port 22
Click ‘Open’ and you will be presented with the ECS0016 login prompt. • (You may also receive a ‘Security Alert’ that the host’s key is not cached, you will need to choose ‘yes’ to continue.)
Using the • Telnet protocol is similarly simple but you use the default port 23
12
Instruction Manual
SSHTerm
Another common communications package that may be useful is SSH­Term, an open source package that can be downloaded from http://sourceforge.net/projects/sshtools
To use SSHTerm for an SSH terminal session from a Windows Client, you simply Select the File option and click on New Connection
A new dialog box will appear for your ‘Connection Profile’ where you can type in the host name or IP address (for the ECS0016 unit) and the TCP port that the SSH session will use (port 22). Then, enter your username and choose password authentication and click Connect.
You may receive a message about the host key fingerprint, and you will need to select ‘yes’ or ‘always’ to continue.
The next step is password authentication, where you will be prompted for your username and password from the remote system.
You will then be logged on to the ECS0016 gateway.
Serial Port and Network Host Conguration
The ECS0016 enables access and control of serially and network attached devices (hosts). The Administrator must configure the port access privileges for each of these devices, and specify the selection of services that can be used to control the devices. The Administrator must also set up Users and specify each User’s individual access and control privileges.
13
Instruction Manual
Conguring Serial Ports
To configure the serial port, you must first set the protocols and the RS232 parameters that are to be used for the data connection to that port (e.g. baud rate).
Then you must select what mode the port is to operate in. Each port can be set to support one of five operating modes:
I
Console Server mode enables remote network access to the attached devices serial console port
I I
SDT mode enables graphical console (RDP, VNC, HTTPS etc) access to hosts that are serially connected
I I I
Power Device mode sets up the serial port to communicate with an intelligent serial controlled power strip
IV
Terminal Server mode sets the serial port to await an incoming terminal login session
V
Serial Bridge mode enables the transparent interconnection of two serial port devices over a network
You can also configure the ECS0016 to support the remote syslog proto­col on a per serial port basis.
Select • Serial & Network: Serial Port and you will see the current labels, modes, and RS232 protocol options that are currently set up for each serial port
If you wish to set the same protocol options for multiple serial ports at • once, click Edit Multiple Ports and select which ports you wish to configure as a group
By default each serial port is set in • Console Server mode. For the por t to be reconfigured, click Edit
14
Instruction Manual
When you have reconfigured the common settings and the mode for • each port, you set up any remote syslog, then click Apply
Common Settings
There are a number of common settings that can be set for each serial port, that are independent of the mode in which the port is being used.
These serial port parameters must be set so they match the port param­eters of the devices you attach to that port:
Specify a label for the port •
Select the appropriate Baud Rate, Parity, Data Bits, Stop Bits and • Flow Control for each port. (Note that the RS485 field is not relevant for ECS0016 gateways)
15
Instruction Manual
Before proceeding with further serial port configuration, you should • connect the ports to the serial devices they will be controlling, and ensure they have matching settings
Please Note that the serial ports are all factory set to RS232 9600 baud, no parity, 8 data bits, 1 stop bit and Console Server Mode.
The baud rate can be changed to 2400 – 230400 baud using the man­agement console. Lower baud rates (50, 75, 110, 134, 150, 200, 300, 600, 1200, 1800 baud) can be configured from the command line.
Console Server Mode
Select Console Server Mode to enable remote management access to the serial console that is attached to this serial port:
Logging Level - specifies the level of information to be logged and monitored
Telnet - With the Telnet service enabled on the ECS0016, a Telnet client on a User or Administrator’s PC/workstation can connect to a serial device attached to this serial port on the gateway. The Telnet communica­tions are unencrypted, so this protocol is generally recommended only for local connections.
16
Instruction Manual
From Win2000/XP/NT, you can run telnet from the command prompt • (cmd.exe)
You can also use standard communications packages like PuTTY to • set a direct Telnet (or SSH) connection to the serial ports (see box below)
Also, if the remote communications are being tunneled with • MetaConnect, then Telnet can be used for securely accessing attached devices
In Console Server mode, Users and Administrators can use MetaCon­nect to set up secure Telnet connections that are SSH tunneled from their client PC/workstations to the serial port on the ECS0016. MetaCon­nect then enables those secure Telnet connections to be selected with a simple point and click.
To use MetaConnect to access consoles on the ECS0016 serial ports, you must configure MetaConnect using the ECS0016 as a gateway, then as a host, with Telnet service on Port (2000 + serial port #) i.e. 2001– 2016 enabled.
MetaConnect can be installed on Windows 2000, XP, 2003, Vista™ PCs and on most Linux platforms. Solaris platforms are also supported, how­ever they must have Firefox installed.
Enter the ECS0016 gateway’s IP address as the ‘Host Name (or IP ad­dress)’. Select ‘Telnet’ as the protocol and set the ‘TCP port’ to 2000 plus the physical serial port number (i.e. 2001 to 2016).
Click the ‘Open’ button. You may then receive a ‘Security Alert’ that the host’s key is not cached - choose ‘yes’ to proceed. You will then be pre­sented with the login prompt of the remote system connected to the serial port chosen on the ECS0016 device, where you can login as normal and use the host serial console screen.
17
Instruction Manual
SSH
It is recommended that you use SSH as the protocol whereby the User or Administrator connects to the ECS0016 gateway (or connects to the attached serial consoles) over the Internet (or any other public network). This will provide authenticated SSH communications between the SSH client program on the remote user’s PC/workstation and the gateway, so the user’s communication with the serial device attached to the gateway is secure.
For SSH access to the consoles on devices attached to the ECS0016 serial ports, you can use MetaConnect. You configure MetaConnect with the ECS0016 as a gateway, then as a host, and you enable SSH service on Port (3000 + serial port #) i.e. 3001-3016.
Also, you can use common communications packages, like PuTTY or SSHTerm to SSH connect directly to por t address IP Address _ Port (3000 + serial port #) i.e. 3001–3016
Alternately, SSH connections can be configured using the standard SSH port 22. The serial port being accessed is then identified by appending a descriptor to the username. This syntax supports any of:
<username>:<portXX>
<username>:<port label>
<username>:<ttySX>
<username>:<serial>
18
Instruction Manual
For a User named ‘Paul’ to access serial port 2, when setting up the SSHTerm or the PuTTY SSH client, instead of typing username = paul and ssh port = 3002, the alternate is to type username = paul:port02 (or username = fred:ttyS1) and ssh port = 22.
Or, by typing username=fred:serial and ssh port = 22, the User is pre­sented with a port selection option:
This syntax enables Users to set up SSH tunnels to all serial ports with only a single IP port 22 having to be opened in their firewall/gateway.
TCP
RAW TCP allows connections directly to a TCP socket. However while communications programs like PuTTY also supports RAW TCP, this pro­tocol would usually be used by a custom application
For RAW TCP, the default port address is IP Address _ Port (4000 + serial port #) i.e. 4001 – 4016.
RAW TCP also enables the serial port to be tunneled to a remote ECS0016 client gateway, so two serial port devices can be transparently interconnect over a network.
RFC2217
Selecting RFC2217 enables serial port redirection on that port. For RFC2217, the default port address is IP Address _ Port (5000 + serial port #) i.e. 5001 – 5016.
Special client software is available for Windows UNIX and Linux that supports RFC2217 virtual com por ts, so a remote host can monitor and manage remote serially attached devices, as though they were connected to the local serial port.
19
Instruction Manual
RFC2217 also enables the serial port to be tunneled to a remote ECS0016 client gateway, so two serial port devices can be transparently interconnect over a network.
Accumulation Period
By default, once a connection has been established for a particular serial port (such as a RFC2217 redirection or Telnet connection to a remote computer) then any incoming characters on that port are forwarded over the network on a character by character basis. The accumulation period changes this by specifying a period of time that incoming characters will be collected before then being sent as a packet over the network.
Escape Character (esc)
This enables you to change the character used for sending escape char­acters. The default is ~.
SDT Mode
This Secure Tunneling setting allows port forwarding of RDP, VNC, HTPP, HTTPS, SSH, Telnet and other LAN protocols through to computers which are locally connected to the ECS0016 by their serial COM port. However such port forwarding requires a PPP link to be set up over this serial port.
Power Strip Mode
This mode configures the selected serial port to communicate with an intelligent serial controlled power strip.
Terminal Server Mode
Select Terminal Server Mode and the Terminal Type (vt220, vt102, vt100, Linux or ANSI) to enable a tty login on the selected serial port.
The getty will then configure the port and wait for a connection to be made. An active connection on a serial device is usually indicated by the
20
Instruction Manual
Data Carrier Detect (DCD) pin on the serial device being raised. When a connection is detected, the getty program issues a login: prompt, and then invokes the login program to handle the actual system login.
Serial Bridging Mode
Serial bridging is the encapsulation of serial data into network packets and the transport of the data over a network. So two ECS0016 gateways can configured to act as a virtual serial cable over IP network.
One gateway is configured as the server in Console Server mode with either RFC2217 or RAW enabled on the serial port to be bridged.
For the client gateway, the serial port must be set in Bridging Mode. To do so:
Select Serial Bridging Mode and specify the IP address of the first ECS0016 gateway and the TCP port address of the remote serial port (for RFC2217 bridging this will be 5001 - 5016)
By default the bridging client will use RAW TCP, so you must select • RFC2217 if this is the console server mode you have specified on the server gateway
You may secure the communications over the local Ethernet by • enabling SSH, however you will need to generate and upload keys

Syslog
In addition to built-in logging and monitoring (which can be applied to seri­al attached and network attached management accesses. The ECS0016

Instruction Manual
can also be configured to support the remote syslog protocol on a per serial port basis.
Select the Syslog Facility/Priority fields to enable logging of traffic on • the selected serial port to a syslog server; and to appropriately sort and action those logged messages (i.e. redirect them/ send alert email etc.)
For example if the computer attached to serial port 3 should never send anything out on its serial console port, the Administrator can set the Facil­ity for that port to local0 (local0 .. local7 are meant for site local values), and the Priority to critical. At this priority, if the ECS0016 syslog server does receive a message, it will automatically raise an alert.
Add / Edit Users
The Administrator uses this menu selection to set up, edit and delete Us­ers and to define the access permissions for each of these Users.
Users can be authorized to access specified ECS0016 serial ports and specified network attached hosts. These Users can also be given full Administrator status (with full configuration and management and access privileges).
To simplify User set up, individual users can be configured as members of Groups. There are two Groups set up by default:
admin which provides User members with full Administrator privileges
and
users which provides User members with access to the Management section of the Management Console
