> Cabling the Channelized Line Cards
> This chapter provides information on the CLC and CLC2 Channelized (STM-1/OC-3) line cards’ physical interfaces and the instructions for installing the cables.
> Channelized Line Card Interfaces
> The CLC and CLC2 Channelized Line Cards are used only in ASR 5000 systems. The CLC or CLC2 is always installed directly behind its active packet processing card in rear slots 17 through 23, 26 through 39, and 42 through 48. You may optionally install it behind a redundant (standby) packet processing card.
> Both the 1-port CLC and 4-port CLC2 cards support two versions of SFP modules. The type of optical fiber interface on the line card is dictated by the Small Form-factor Pluggable (SFP) modules installed on the card. The SFP modules are hot-pluggable.
> SFP Modules Supported by the Channelized Line Card

> Module Type | Card Identification | Interface Type | Cable Specifications

> Cabling the Optical SFP Interface
> To use the optical SFP interface on the a channelized line card, follow the instructions below.
> Warning: Only trained and qualified personnel should install, replace, or service this equipment. Invisible laser radiation may be emitted from the aperture of the port when no cable is connected. Avoid exposure to laser radiation and do not look into open apertures. Be sure to keep the cover on the interface when it is not in use. Laser Klasse 1 - nur speziell ausgebildetes Personal darf dieses Geraet warten. Nicht in den Laser schauen, um Augenverletzungen zu vermeiden. Nicht genutzte Buchsen mit der entsprechenden Kappe verschliessen.

> Step 1 | Remove the cover from the SFP interface.

> Step 2 | Insert the optical cable into the interface and ensure that it is securely in place.
