▄ Cisco ASR 5000 Series Product Overview
OL-22938-02
System Management Cards (SMC) : Provides full system control and management of all cards within the ASR
5000 platform. Up to two SMC can be installed; one active, one redundant.
Packet Services Cards (PSC/PSC2) : Within the ASR 5000 platform, PSCs/PSC2s provide high-speed, multi-
threaded EPS Bearer context processing capabilities for MME services. Up to 14 PSCs/PSC2s can be installed,
allowing for multiple active and/or redundant cards.
Switch Processor Input/Outputs (SPIOs) : Installed in the upper-rear chassis slots directly behind the
SPCs/SMCs, SPIOs provide connectivity for local and remote management, central office (CO) alarms. Up to
two SPIOs can be installed; one active, one redundant.
Line Cards : The following rear-loaded line cards are currently supported by the system:
Ethernet 10/100 and/or Ethernet 1000 Line Cards : Installed directly behind PSCs, these cards
provide the physical interfaces to elements in the LTE/SAE network. Up to 26 line cards should be
installed for a fully loaded system with 13 active PSCs/PSC2, 13 in the upper-rear slots and 13 in the
lower-rear slots for redundancy. Redundant PSCs/PSC2s do not require line cards.
Quad Gig-E Line Cards (QGLCs) :The 4-port Gigabit Ethernet line card is used in the ASR 5000
system only and is commonly referred to as the Quad-GigE Line Card or the QGLC. The QGLC is
installed directly behind its associated PSC/PSC2 to provide network connectivity to the packet data
network.
10 Gig-E Line Cards(XGLCs) : The 10 Gigabit Ethernet Line Card is used in the ASR 5000 system
only and is commonly referred to as the XGLC. The XGLC supports higher speed connections to
packet core equipment, increases effective throughput between the ASR 5000 and the packet core
network, and reduces the number of physical ports needed on the ASR 5000.
The one-port XGLC supports the IEEE 802.3-2005 revision which defines full duplex operation of 10
Gigabit Ethernet.
The XGLC is configured and monitored via the System Management Card (SMC) over the system‘s
control bus. Both SMCs must be active to maintain maximum forwarding rates.
Redundancy Crossbar Cards (RCCs): Installed in the lower-rear chassis slots directly behind the SPCs/SMCs,
RCCs utilize 5 Gbps serial links to ensure connectivity between Ethernet 10/100/Ethernet 1000/Quad Gig-E/10
Gig-E line cards and every PSC/PSC2 in the system for redundancy. Two RCCs can be installed to provide
redundancy for all line cards and PSCs/PSC2a.
Important:
Additional information pertaining to each of the application and line cards required to support
LTE/SAE services is located in the Hardware Platform Overview chapter of the Product Overview Guide .
Operating System Requirements
The MME is available for ASR 5000 platforms running StarOS™ Release 9.0 or later.
