Operating System Requirements
The PDIF operates on the ASR 5000 running StarOS Release 8.1 or later.
Platforms
The PDIF operates on the ASR 5000.
Hardware Requirements
System Management Cards (SMCs): SMCs provide full system control and management of all cards within
the ASR 5000. Up to two SMCs can be installed; one active, one redundant.
Packet Services Cards (PSCs/PSC2s): PSCs provide high-speed, multi-threaded PDP context processing
capability. Up to 14 PSCs 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. Up to 2 SPIOs can be installed: one active, one
redundant.
Line Cards: Installed directly behind the PSCs, these cards provide the physical interfaces from the PDIF to
various elements in the network. Up to 26 line cards can be installed for a fully loaded system with 13 active
PSCs: 13 in the upper-rear slots and 13 in the lower-rear slots for redundancy. Redundant PSCs do not require
line cards. Ethernet 10/100 Fast Ethernet and/or Gigabit Ethernet 1000 and/or four-port Quad Gig-E line cards
(QGLCs) all provide redundant IP connections.
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 in the system for redundancy. Two RCCs can be installed to provide redundancy
for line cards and PSCs.
