The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

This chapter describes the system planning considerations for your Cisco CRS Series 16-Slot Line Card Chassis Enhanced installation. It includes the following sections:
Following is a list of tasks to configure the line card chassis for high availability, which helps to ensure that service is not disrupted due to failures:
The Cisco CRS distributed route processor (DRP) and its companion card (DRP PLIM) are optional components that can be installed in the line card chassis to provide enhanced routing capabilities for Cisco CRS routers. The DRP is installed in any MSC slot. The DRP PLIM is installed in the corresponding PLIM slot.
Before installing a Cisco CRS Series 16-Slot Line Card Chassis Enhanced, you must carefully plan the facility power required to support it. The power requirements are based on the number of line card chassis that you plan to install. When planning the power layout for a routing system, you should also include the power requirements of peripheral equipment (such as the external terminals), the network management equipment, and the test equipment you will use with your system.
For larger system configurations, it may be advisable to consult with a facilities electrical expert to understand the load that a routing system may put on the power plant of your facility. Always follow local electrical codes.
Note | Power and Cooling Requirements provides detailed power and cooling requirements. |
As the size of the routing system increases, the cabling required for the chassis increases. For example, a fully loaded chassis has more cables connected to it than a partially loaded chassis.
The cabling runs must be carefully planned. The basic configurations for various routing systems should be arranged to minimize the complexity and length of the cable runs. Terminated cables are considered part of the basic configuration.
You must provide the line card- PLIM interface cables and the cable management trays for these cables from the Cisco CRS 16-Slot Line Card Chassis Enhanced router to your facility interconnect.
Because the type and number of MSCs, FPs, and PLIMs vary with each routing system site, plan these data cable runs in advance of the system installation.
When planning the data cable runs, consider the:
The line card chassis has built-in noise reduction, such as fan speed control.
Cisco or a Cisco partner can provide a total installation, from planning to test and turn-up. For information about Cisco (or Cisco partner) installation services, contact Cisco Customer Advocacy.
After a Cisco CRS Series 16-Slot Line Card Chassis Enhanced router has been installed, it has to be tested and certified. Contact Cisco Customer Advocacy for information about testing, certification, and warranties.
