Connecting to the Console and Auxiliary Ports
Caution
The ports labeled Ethernet, 10BASE-T, Token Ring, Console, and AUX are safety
extra-low voltage (SELV) circuits. SELV circuits should only be connected to
other SELV circuits.
Note
RP cables are not available from Cisco, but are available from any commercial
cable vendor.
Note
To comply with Telcordia GR-1089 NEBS standard for electromagnetic
compatibility and safety, connect all console, auxiliary, Ethernet, and
BITS (PRP2) interfaces only to intrabuilding or nonexposed wiring or cabling.
The intrabuilding cable must be shielded and the shield must be grounded at both
ends.
