l Do not twist, bend, stretch, or extrude fibers during installation.
l Cover the idle fiber connectors with dust caps. Remove the dust caps before using the
fiber connectors.
Requirements for Cable Routing
l To protect cables, remove the burrs in the cable through-holes or install protective rings
in the holes.
l To ease the connection and to avoid stress, keep cable joints slack. After connecting
multiple cables to a connector that has multiple interfaces, keep the cables slack to avoid
generating stress.
l Bind or clean cables gently because cable distortion affects signal quality.
l Keep cables away from moveable components such as doors.
l Sharp objects must not touch cable wiring to prevent damage to cables.
l To protect power cables, route power cables of the active and standby power modules
separately.
