Information About Small Form-Factor Pluggable (SFP) Modules

The SFP module for the line card chassis uses the bale clasp latch type.
Protect the SFP modules by inserting clean dust covers into them after the cables are removed from them.
Caution
Be sure to clean the optic surfaces of the fiber cables before you plug them back into the optical ports of
another SFP module. Avoid getting dust and other contaminants into the optical ports of the SFP
modules: The optics do not work correctly when obstructed with dust.
Only the 16-port OC-48c/STM-16c MSC uses SFP modules.
Note

Information About Hard Drives and PCMCIA Cards

Optional and replaceable hard drives and PCMCIA cards are available for the DRP cards.
The hard drive is an IDE hard drive used for gathering debugging information, such as core dumps from
the DRPs or MSCs. The IDE hard drive is typically powered down and activated only when there is a
need to store data. The drive is not vital to a functioning chassis and is optional.
Core dumps are discoverable only through intervention with the chassis system software.
Note
Physically, the DRP hard drive is a hot-pluggable PC board and sled-mounted drive with a connector
interface that gets cleanly seated into a route processor card. In general, removal and replacement of this
drive is not required.
The DRP cards provide two PCMCIA flash slots, each card providing up to 1 GB of flash storage. One
of the PCMCIA flash subsystems is accessible externally, is removable, and allows you to transfer
images and configurations by plugging in a PCMCIA flash card. The other subsystem is fixed to the
DRP, not removable, and for permanent storage of configurations and images.

Information About Cable Management Brackets

The Cisco ASR 14000 series 8-slot line card chassis includes a cable management system that organizes
the interface cables entering and exiting the different cards, keeping them out of the way and free of
sharp bends.
Excessive bending of interface cables can damage the cables.
Caution
The Cisco ASR 14000 series 8-slot line card chassis arrives preinstalled with a horizontal cable
management bracket on the front of the chassis and an optional horizontal cable management bracket
orderable for the rear of the chassis.
