Hardware Compliance
Use only shielded cables.
Ensure that cable distance and rate limits meet IEEE-recommended maximum
speeds and distances for signaling purposes. For information about
attenuation and power loss in optical fiber cables see:
ANSI T1.646a-1997 Telecommunications – Broadband ISDN - Physical
Layer Specification for User-Network Interfaces Including DS1/ATM (1997)
ANSI T1.646-1995 Telecommunications – Broadband ISDN - Physical
Layer Specification for User-Network Interfaces Including DS1/ATM (1995)
Ensure that power cables deliver sufficient power to the system.
Attach laser fiber connectors only to Class 1 laser devices in accordance with
IEC 825-1, Safety of Laser Products - Part 1.
Route cables so that they do not restrict ventilation or airflow.
Route cables so that modules and field-replaceable units are easily accessible.
Route cables in a logical direction to prevent loss of connectivity to other
equipment in the rack, associated equipment in adjacent racks, or to the
backbone network.
Consider using cable-management brackets to keep network cables untangled
and orderly and to prevent cables from hindering access to other slots.
For specifications on cables for line modules, see the E-series Module Guide.
