Chapter 1 Overview and Physical Description
Power System
For line card installation information, see the Cisco ASR 9000 Series Aggregation Services Routers
Ethernet Line Card Installation Guide.
In addition to the line cards listed here, a SPA Interface Processor (SIP) and Shared Port Adapters (SPA)
are supported on the Cisco ASR 9000 Series Routers. For information about these components, see the
Cisco ASR 9000 Aggregation Services Router SIP and SPA Hardware Installation Guide.
Line Card Front Panel and Access Ports
Each line card drives a set of three alarm output contacts, one set for each of Critical, Major, and Minor.
Alarm circuitry on the RSP/RP activates dry contact closures that are accessible through a nine-pin
connector on the RSP/RP faceplate.
See the “Ethernet Line Cards” section on page 2-21 for a description of each line card’s front panel
indicators and their meaning.
Line Card Serviceability
Line cards can be inserted or removed when adjacent (cabled) RSP or line cards are installed.
Line Card Ejector Levers
Ejector levers are provided for inserting and removing line cards from the backplane connectors.
Insertion and removal force of the card ejector levers is about 16 lbs (7.27 kg).
Power System The Cisco ASR 9000 Series Routers can be powered with an AC or DC source power. The power system
provides power for the cards and fan trays.
The power system is based on a distributed power architecture centered around a –54 VDC printed
circuit power bus on the system backplane.
The –54 VDC system backplane power bus can be sourced from one of two options:
• AC systems—AC/DC bulk power supply tray connected to the user 200 to 240 VAC +/- 10 percent
(180 to 264 VAC) source
• DC systems—DC/DC bulk power supply tray connected to the user Central Office DC battery
source –48 VDC/–60 VDC (–54 VDC nominal)
DC output power from each power tray is connected to the router by two power blades that mate to the
power bus on the backplane. The system backplane distributes DC power through connectors on the
backplane to each card and the fan trays. Each card has on-board DC–DC converters to convert the
–54 VDC from the distribution bus voltage to the voltages required by each particular card.
