RADIO FREQUENCY INTERFERENCE STATEMENTS
This equipment generates, uses, and can radiate 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 communication. It has been tested
and found to comply with the limits for a Class A computing device in accordance with the specifications in Subpart J of
Part 15 of FCC rules, which are designed to provide reasonable protection against such interference when the equipment is
operated in a commercial environment. Operation of this equipment in a residential area is likely to cause interference, in
which case the user at his own expense will be required to take whatever measures may be necessary to correct the
interference.
Changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to
operate the equipment.
This digital apparatus does not exceed the Class A limits for radio noise emission from digital apparatus set out in the Radio Interference
Regulation of Industry Canada.
Le présent appareil numérique n’émet pas de bruits radioélectriques dépassant les limites applicables aux appareils numériques de
classe A prescrites dans le Règlement sur le brouillage radioélectrique publié par Industrie Canada.

que producen calor.
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 eliminada.
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; u
B: Objectos han caído o líquido ha sido derramado
dentro del aparato; o
C: El aparato ha sido expuesto a la lluvia; o
D: El aparato parece no operar normalmente o
muestra un cambio en su desempeño; o
E: El aparato ha sido tirado o su cubierta ha sido
dañada.

CHAPTER 2: Introduction
7
The Ethernet to Token Ring Bridge is a two-port bridge that provides connectivity between devices on a
token-ring LAN (local area network) and an Ethernet LAN. (See Figure 2-1.)
All bridges are controlled by the Bridge Manager, a software program that runs on a PC on the token-ring
LAN. The Bridge Manager performs control and statistics-gathering functions on one or more bridges and
can download operating-code upgrades to the bridges through the network.
A PC running Bridge Manager may also be attached directly to the serial control port on the Ethernet to
Token Ring Bridge. For more information, see Section 5.7.
Figure 2-1. The Ethernet to Token Ring Bridge provides
a transparent connection between the two LANs.
