Warning Varning! Denna varningssymbol signalerar fara. Du befinner dig i en situation som kan leda till
personskada. Innan du utför arbete på någon utrustning måste du vara medveten om farorna med
elkretsar och känna till vanligt förfarande för att förebygga skador. Se förklaringar av de varningar
som förkommer i denna publikation i dokumentet Regulatory Compliance and Safety Information
(Efterrättelse av föreskrifter och säkerhetsinformation), vilket medföljer denna anordning.
Warning Read the installation instructions before you connect the system to its power source.
Warning Only trained and qualified personnel should be allowed to install or replace this equipment.
Warning Before working on a chassis or working near power supplies, unplug the power cord on AC units;
disconnect the power at the circuit breaker on DC units.
Warning Ultimate disposal of this product should be handled according to all national laws and regulations.
Caution To avoid damaging ESD-sensitive components, discharge all static electricity from your body before
opening the chassis. Before performing procedures described in this document, review the sections
“Safety with Electricity,” “Safety with Electricity,” and “Tools and Equipment Required.”
Note The following warnings are only applicable if a single-mode Fiber Distributed Data Interface (FDDI or
Basic Rate Interface (BRI) network processor module are installed in the router together with 2T16S
network processor modules. If you do not have these modules installed in your router, proceed with the
section “Overview of the 2T16S Network Processor Module on page 5.
Warning The ports labeled “Ethernet,” “10BaseT,” “Token Ring,” “Console,” and “AUX” are safety extra-low
voltage (SELV) circuits. SELV circuits should only be connected to other SELV circuits. Because the
BRI circuits are treated like telephone-network voltage, avoid connecting the SELV circuit to the
telephone network voltage (TNV) circuits.
Warning The ISDN connection is a source of voltage that should be inaccessible to user contact. Do not attempt
to tamper with or open any public telephone operator (PTO)-provided equipment or connection
hardware. Any hardwired connection (other than by nonremovable, connect-one-time-only lug) must
be made only by PTO staff or suitably trained engineers.
Warning Network hazardous voltages are present in the BRI cable. If you detach the BRI cable, detach the end
away from the router first to avoid possible electric shock. Network hazardous voltages also are
present on the system card in the area of the BRI port (RJ-45 connector), regardless of when power is
turned off.
