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 “

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.
