The CSS 11506 not only supports redundancy in SCMs but also supports
redundant power supplies and redundant Switch Modules (20 Gbps each).
The CSS modules are as follows:
• 144 MB or 288 MB (128 MB or 256 MB of usable memory) Switch Control
Module (SCM) with:
–
Two 1000-Mbps Ethernet (1000BASE-SX or LX) small-form factor
pluggable gigabit interface converters (SFP GBICs) with LC-type
connectors.
–
Two PCMCIA slots for a hard or flash disk drive for the system software,
and logging and off-line system files.
–
RJ-45 RS-232 Console port
–
1 RJ-45 10-Mbps half-duplex Ethernet management connector.
• Switch Module (SM). An SM provides connectivity among the SCM and
IOMs.
–
The CSS 11503 has a single integrated SM. A single SM has an aggregate
throughput of 20 Gbps.
–
The CSS 11506 has two removable SMs that share the switching
functions. Two SMs provide 40 Gbps aggregate throughput. As
implemented in WebNS 5.10 and greater, if one SM fails, the CSS
reboots and continues to operate through the other SM.
• Two slots in the CSS 11503 and five slots in the CSS 11506 are configurable
with:
–
Fast Ethernet Modules that provide either 8 or 16 auto-sensing
10/100-Mbps Ethernet (
10BASE-T/100BASE-TX) RJ-45 ports.
–
Gigabit Ethernet Modules provides up to two 1000-Mbps Ethernet
(1000BASE-SX or LX) SFP GBICs with LC-type connectors.
–
A Session Accelerator Module (SAM) that provides a cost-effective way
to add flow performance when additional connectivity is not required.
Using the same flow setup and forwarding processors as the I/O modules,
it provides the flexibility to optimize the CSS for port density and
performance.
