Compliance Information
Radio
and TV
Interference
The WAN Access Router generates and uses radio frequency energy, and if not installed and used properly-that
is, in strict accordance with the manufacturer’s instructions-may cause interference to radio and television
reception. The WAN Access Router have been tested and found to comply with the limits for a Class A com-
puting device in accordance with specifications in Subpart B of Part 15 of FCC rules, which are designed to
provide reasonable protection from such interference in a commercial installation. However, there is no guar-
antee that interference will not occur in a particular installation. If The WAN Access Router does cause inter-
ference to radio or television reception, which can be determined by disconnecting the unit, the user is
encouraged to try to correct the interference by one or more of the following measures: moving the computing
equipment away from the receiver, re-orienting the receiving antenna and/or plugging the receiving equipment
into a different AC outlet (such that the computing equipment and receiver are on different branches).
CE Notice
The CE symbol on your Black Box equipment indicates that it is in compliance with the Electromagnetic
Compatibility (EMC) directive and the Low Voltage Directive (LVD) of the European Union (EU). A Certifi-
cate of Compliance is available by contacting Technical Support.

11. El aparato eléctrico deberá ser connectado a una fuente de poder sólo del tipo descrito en el instructivo
de operación, o como se indique en el aparato.
12. Precaución debe ser tomada de tal manera que la tierra fisica y la polarización del equipo no sea elimi-
nada.
13. Los cables de la fuente de poder deben ser guiados de tal manera que no sean pisados ni pellizcados
por objetos colocados sobre o contra ellos, poniendo particular atención a los contactos y receptáculos
donde salen del aparato.
14. El equipo eléctrico debe ser limpiado únicamente de acuerdo a las recomendaciones del fabricante.
15. En caso de existir, una antena externa deberá ser localizada lejos de las lineas de energia.

16. El cable de corriente deberá ser desconectado del cuando el equipo no sea usado por un largo periodo
de tiempo.
17. Cuidado debe ser tomado de tal manera que objectos liquidos no sean derramados sobre la cubierta u
orificios de ventilación.
18. Servicio por personal calificado deberá ser provisto cuando:
— A: El cable de poder o el contacto ha sido dañado; o
— B: Objectos han caído o líquido ha sido derramado dentro del aparato; o
— C: El aparato ha sido expuesto a la lluvia; o

WAN Access Routers Getting Started Guide 1 • General Information
WAN Access High Speed Routers overview
The WAN Access Routers of gateway routers/bridges combine full set of high-speed IP routing features and
WAN access via PPP/IP/FR protocols. All WAN Access Routers come with an auto-sensing full-duplex
10/100Base-T Ethernet port, MDI-X cross-over switch, console port, and internal or external power supply.
There are three versions in the WAN Access Routers corresponding to a choice of WAN interface:
•The LR120A is equipped with an integrated T1/E1 CSU/DSU for connection to full and fractional
T1/E1 services.
•The LR121A is equipped with DTE/DCE user configurable X.21 interface.
•The LR122A equipped with a V.35 interface presented on a female DB-25 connector and a cable to con-
nect to an M/32-F.
The WAN Access Routers provide selectable bridging or routing functionality along with advanced IP features
such as NAT/NAPT, Firewall, and DHCP. A complete set of configurable PPP/IP/FR WAN protocols allow a
wide range of choices when connecting branches via common WAN services. The WAN Access Routers boast
easy installation offering Console/VT-100, Telnet, HTTP, and SNMP management options.
The following sections describe WAN Access Router features and capabilities:
•General attributes, see section “General attributes”
