5000 platform in SCM service.
Hardware Requirements
Information in this section describes the hardware required to properly enable SCM services.
Platforms
The SCM operates on the ASR 5000.
System Hardware Components
The following application and line cards are required to support SCM functionality on an ASR 5000 platform:
System Management Cards (SMCs): 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 (PSCs/PSC2s): Within the ASR 5000 platform, PSCs provide high-speed, multi-
threaded PDP context processing capabilities for 2.5G SGSN, 3G SGSN, and GGSN services. Up to 14 PSCs
can be installed, allowing for multiple active and/or redundant cards.
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 SMCs,
SPIOs provide connectivity for local and remote management, Central Office (CO) alarms. Up to two SPIOs
can be installed; one active, one redundant.
can be installed; one active, one redundant.
Line Cards: Installed directly behind PSC/PSC2, these cards provide the physical interfaces to elements in the
GPRS/UMTS data network. Up to 26 line cards can be installed for a fully loaded system with 13 active
PSCs/PSC2s, 13 in the upper-rear slots and 13 in the lower-rear slots for redundancy. Redundant PSCs/PSC2s
do not require line cards.
PSCs/PSC2s, 13 in the upper-rear slots and 13 in the lower-rear slots for redundancy. Redundant PSCs/PSC2s
do not require line cards.
Ethernet 10/100 and/or Ethernet 1000 line cards/Quad Gig-E Line Cards (QGLC) for IP connections to
the GGSN, SGSN, or other network elements.
Redundancy Crossbar Cards (RCCs): Installed in the lower-rear chassis slots directly behind the SMCs, RCCs
utilize 5 Gbps serial links to ensure connectivity between Ethernet 10/100 or Ethernet 1000 line cards/QGLCs
and every PSC/PSC2 in the system for redundancy. Two RCCs can be installed to provide redundancy for all
line cards and PSCs/PSC2s.
