Chapter 1
Introducing the Contivity Extranet Switch
The Switch
The Nortel Networks Contivity Extranet Switch 1500 Series provides scalable,
secure, manageable extranet access for up to 100 simultaneous users across the
Public Data Network (PDN). The Contivity Extranet Switch 1500 Series consists
of the 1500, 1510, 1520, and 1530 models.
The Switch includes the most popular tunneling protocols, IP Security (IPsec),
Point-to-Point Tunneling Protocol (PPTP), Layer 2 Forwarding Tunneling
Protocol (L2TP), and Layer 2 Forwarding (L2F). IPsec uses digital certificates,
password-based keys, and tokens for authentication; PPTP, L2TP, and L2F use
Challenge Handshake Authentication Protocol (CHAP) or Password
Authentication Protocol (PAP) for authentication. The PPTP implementation for
the Switch supports MS-CHAP authentication with 56- to 128-bit key encryption.
Figure 1-1 shows an intranet and an extranet.

Figure 1-1. An Intranet and the Internet Make Up an Extranet
The Switch provides more security than traditional remote access schemes due to
the combination of authorization, authentication, privacy, and access control on a
per user basis. Additionally, the IPsec protocol and related Internet Security
Association & Key Management Protocol (ISAKMP) and the Oakley key
establishment protocol support further enhance the security offering.
For authentication and access control, the Switch supports an internal or external
Lightweight Directory Access Protocol (LDAP) server and external Remote
Authentication Dial-In User Service (RADIUS) servers.

To restrict access, the Switch uses packet filtering based on Protocol ID,
Direction, Source and Destination IP addresses, Source and Destination Ports,
and TCP connection establishment. Additionally, Nortel Networks provides
you with a set of predefined filters that you can use either directly or tailor to
your network needs.
The unique quality of service (QoS) mechanisms include call admission
and packet forwarding priorities, and support for Resource ReSerVation
Protocol (RSVP).
The HTML and Java Web management interface allows different Switch
administrators to have different access rights, including configuration, status, and
monitoring. The Switch offers RADIUS accounting support and extensive
logging, including events, system, configuration, and security logs.

Preparing Your Site
This chapter provides information that you should read before you begin cabling
and configuring the Contivity Extranet Switch 1500 Series. This information
includes selecting an appropriate site, safety guidelines, information on the power
cord, voltage settings, and external vent cooling and airflow recommendations.
Selecting a Site
This Switch is designed to operate reliably in a typical office environment. You
should select a site that meets the following criteria:
• Has a desktop or surface that is off the floor.
• Has access to a grounded, three-pronged power outlet.
- Uses a NEMA 5-15R outlet for 100-120 VAC or a NEMA 6-15R
outlet for 200-240 VAC (US and Canada).
- Uses a three-pronged power outlet that is applicable for the region’s
electrical code (elsewhere).
• Remains dust free and clean.
• Is away from heat sources and is well ventilated.
• Allows adequate clearance for cooling and airflow -- about 10 centimeters
(3.93 inches) in back, 5 centimeters (1.96 inches) on each side, and 10
centimeters (3.93 inches) in front.

Safety Guidelines
Hazardous Conditions Inside the Switch
Hazardous voltage, current, and energy levels are present inside the Switch. Do
not open the Switch; there are no user-serviceable parts inside. Contact Nortel
Networks Customer Support for service.
Switch Power ON/OFF
The On/Off power button on the front panel of the Switch does not completely
eliminate (turn off) the AC power from the Switch. To eliminate AC power from
the Switch completely, unplug the AC power cord from the power supply or wall
outlet.
Check the Voltage Switch
Before you connect the power cord to the back panel of the Switch, ensure that the
voltage selector switch is correctly set to the appropriate AC line source voltage.
For line voltages between:
• 100 and 127 VAC, set the power supply line voltage selector to
115V (115 VAC).
• 200 and 240 VAC, set the power supply line voltage selector to
230V (230 VAC).
Verify that the correct voltage (115V or 230V) is visible on the switch. See Figure
3-1 on page 3-2.
WARNING: Incorrectly setting the voltage will damage the
power supply. See Figure 3-1 on page 3-2.
CAUTION: Make sure that the power service connection is through an
outlet that is properly grounded.

External Vent Cooling and Airflow
The Switch has external vents for cooling and air flow on:
• The chassis bezel
• The back panel
• On each of the side panels
Keep the side vents clear of obstruction to ensure proper cooling of the Switch.
