Chassis Overview
The 16 slots in the LCC can contain the following:
- Modular services cards (MSCs)
- Forwarding processor (FPs) cards
- Label switch processor (LSP) cards
Note |
MSCs, FPs, and LSPs are referred to as line cards. |
- Associated physical layer interface modules (PLIMs)
- SPA Interface Processors (SIPs)
The LCC supports 40G, 140G, and 400G fabric cards, as follows:
- The Cisco CRS-1 Carrier Routing System uses fabric cards designed for 40 G operation (CRS-16-FC/S or CRS-16-FC/M cards).
- The Cisco CRS-3 Carrier Routing System uses fabric cards designed for 140G operation (CRS-16-FC140/S or CRS-16-FC140/M cards).
- The Cisco CRS-X Carrier Routing System uses fabric cards designed for 200G operation (CRS-16-FC400/S or CRS-16-FC400/M cards in 200G mode).
A mixture of 40G, 140G, and 400G fabric cards is not supported except during migration.
Note |
Throughout this document, the generic term Cisco CRS Carrier Routing system refers to the Cisco CRS-1, Cisco CRS-3, and Cisco CRS-X Carrier Routing Systems, unless otherwise specified. |
The LCC is secured to the floor and has locking front and rear doors (the front and rear doors are optional).
Note |
For safety, the chassis must be secured following the installation procedures for the site. |
