SECURITY
Link Security
The EST-9600 tunnels HDLC serial protocols encrypted or non-encrypted. The EST-9600
default is encryption enabled. For private networks that are already considered to be
sufficiently secure, turning encryption off may be an acceptable mode of operation.
The EST-9600 has default pass phrases. If encryption is turned on, be aware that the pass
phrases should be changed from the default values.
Management Security
The EST-9600 can be managed via the Serial Setup port, via Telnet, or via a Web Browser. The
serial port can be enabled or disabled using switch 2 on the rear of the unit. Switch 2 must be
up for the serial management port to be active.
The encrypted HDLC data is sent via the ethernet interface. This is the same interface used to
access telnet or browser management. The telnet port can be enabled or disabled. The telnet
port is a non-standard port 8000. This provides some degree of security, as the default port for
telnet is port 23.
Management using the browser port can also be enabled or disabled. In addition, the browser
port can be limited to only 1 or 2 specific IP addresses.
CONNECTIONS
Connect the synchronous port to the equipment using an appropriate cable. See Section 6 for
pinouts and cabling guidance.
Connect the Ethernet port to the local area network using standard ethernet cables. A straight
through patch cord is used for connection to a hub or switch. To other equipment, a crossover cable
may be required.
