Cabling Summary
The following sections describe cabling requirements.
Fibre Optic Cable Requirements
Each 16-port card slot supports up to sixteen fiber optic transceivers and cables
that convert electrical signals to optical signals and back. Each SFP transceiver
supports 850nm Short Wave Length (SWL) on multimode fiber optic cable, or
1310 nm Long Wave Length (LWL) on single mode fiber optic cable. The
strength of the signal is determined by the type of SFP in use.
Managing Cables
It is important to plan how to route switch cables through the Core Switch 2/64, so
that cables are not compromised. Follow these cabling guidelines:
Core Switch 2/64 V4.1 Installation Guide
Route fiber optic cables directly downwards, instead of across adjacent cards
or in front of the power supplies. This prevents having to disconnect cables
when removing neighboring cards, and also keeps LEDs visible.
Leave at least one meter of slack for each fiber optic cable. This provides
room to remove and replace the 16-port card, allows for inadvertent
movement of the rack, and helps prevent bending the cables.
Use the cable guides provided with the Core Switch 2/64 to group cables by
trunking ports (groups of four neighboring ports, or quads). These guides help
to keep individual ports accessible by keeping the cables evenly spaced, and
also provide clearance for the removal of a neighboring card.
Do not route cables in front of the exhaust vent (located at the top of the port
side of the chassis).
