CHAPTER 1
Preparing for Installation
This chapter guides you through the process of preparing for router installation.
Before installing your Cisco ASR 9901 or Cisco ASR 9001 Router, you must consider these requirements:
• Power and cabling requirements must be in place at your installation site.
• Special equipment must be available for installing the router.
• The environmental conditions that your installation site must meet to maintain normal operation.
The shipping package for the router is engineered to reduce chances of product damage that may result from
routine material handling during shipment:
• Keep the router in the shipping container until you have determined the installation site.
• The router should always be transported or stored in its shipping package in the upright position.
Inspect all items for shipping damage. If an item appears damaged, contact a Cisco customer service
representative immediately.
This chapter contains these installation topics:
•Overview, on page 1
•Safety Guidelines, on page 3
•Site Requirement Guidelines, on page 6
•Port Connection Guidelines, on page 35
Overview
Cisco ASR 9901 Router
The Cisco ASR 9901 Router is a compact high-capacity provider edge (PE) router that delivers 456 Gbps of
non-blocking, full-duplex fabric capacity in a two-rack-unit (2RU) form factor.
The Cisco ASR 9901 Router supports Cisco IOS XR 64-bit releases only.

The Cisco ASR 9901 Router has an integrated route processor (RP) and 42 fixed-configuration ports that
support the following data rates:
• 24 ports that support 1 GE (using SFP) or 10 GE (using SFP+).
1GE copper SFPs are not supported in converted dual-rate ports.
Note
• 16 ports that support 1 GE (using SFP).
1GE copper SFPs operate only on 1000BASE-T rates; autonegotiation and speed
configurations are not supported.
Note
• 2 ports that support 100 GE (using QSFP28).
The base chassis has a GPS input for stratum-1 clocking, building integrated timing supply (BITS) ports, and
management ports. The following figure shows the front panel of the Cisco ASR 9901 Router.

Cisco ASR 9001 Router
The Cisco ASR 9001 Router is a compact high-capacity provider edge (PE) router that delivers 120 Gbps of
non-blocking, full-duplex fabric capacity in a two-rack-unit (2RU) form factor. Similar to other routers in the
Cisco ASR 9000 Series, running Cisco IOS XR software images, the Cisco ASR 9001 Router delivers the
features and services found on the ASR 9000 Series platforms, allowing customers to standardize on the same
Cisco IOS XR image. The Cisco ASR 9001 Router has an integrated route processor (RP) and two modular
bays that support 1 GE, 10 GE and 40 GE modular port adapters (MPAs). The base chassis has four integrated
10 GE enhanced small form-factor pluggable (SFP+) ports, a GPS input for stratum-1 clocking, building
integrated timing supply (BITS) ports, and management ports. The following figure shows the front panel of
the Cisco ASR 9001 Router.
