Director and Switch Connectors

Multimode or single-mode cables attach to Director 2/64, Director 2/140, Edge
Switch 2/16, Edge Switch 2/24, and Edge Switch 2/32 ports with SFP optical
transceivers with LC duplex connectors.
and LC duplex connector.

Routing Fiber-Optic Cables

Follow a logical plan for routing fiber-optic cables to avoid confusing connections
during installation and operation. Route cables from the access holes at the bottom
or top of the equipment rack, then to director and switch ports.
Leave enough slack in the cables to allow cable movement for UPM card or
optical transceiver removal and replacement, or possible rerouting of the cable to
another port.
When routing fiber-optic cables and estimating cable lengths, consider:
SAN High Availability Planning Guide
Cable routing inside the equipment rack to different port locations, and
installation position of the director or switch (top or bottom of the rack). Plan
for 1.0 meter (39.37 inches) of extra cable for routing through restraint
mechanisms and rerouting cables to other ports.
Cable routing outside the equipment rack. Plan for 1.5 meters (5 feet) of cable
outside the rack to provide slack for service clearance, limited rack
movement, and inadvertent cable pulls.
Cabling distance to servers, storage devices, and other fabric elements
(for multi-switch fabric support).
