I/O Module for the Cisco CSS 11500 Content Services Switch

The Cisco CSS 11500 I/O module delivers port density and ﬂow performance. Theproduct line supports three types

of I/O modules:

• Two-port Gigabit Ethernet

• Sixteen-port Fast Ethernet

• Eight-port Fast Ethernet

The Fast Ethernet ports are 10/100BASE-TX with standard RJ-45 connectors, whereas the Gigabit Ethernet ports

require small-form factor GBICs (1000BASE-SX or 1000BASE-LX).

Session Accelerator Module for the Cisco CSS 11500 Content Services Switch

The session accelerator module is 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 system for port density and performance.

Bundles and Defaults

The default product bundle CSS11506-2AC comes with the CSS 11506 chassis, one switch control module with

one hard disk, two switch modules, two AC power supplies, and a tray with fans.

CSS11506 options include redundant switch control modules, SSL modules, session accelerator modules and all

I/O modules.

The default product bundle CSS11503-AC comes with the CSS 11503 chassis, which has an integrated power

supply, fan, and switch module, and one switch control module with one hard disk.

CSS11503 options include SSL modules, session accelerator modules, and all I/O modules.

The switch control modules, I/O modules, and session accelerator modules all ship with 144 MB of RAM.

The SSL module has no conﬁgurable options and comes with a ﬁxed 512 MB of SDRAM.

GBICs are not included with any module and must be ordered separately.

Memory

RDRAM can be upgraded from 144 MB to 288 MB on switch control modules, I/O modules, and session

accelerator modules.

The amount of memory in the system determines the maximum number of simultaneous ﬂows the system can store.

Each module supports either 144 MB of RDRAM (128 MB usable) or 288 MB of RDRAM (256 MB usable).

Because any ﬂow coming in to any port of the system can be stored on any module in the system, all modules in

the system should have the same amount of memory. Either all should have 144 MB or all should have 288 MB

of RDRAM.

Standby switch control modules should have the same amount of memory as active switch control modules, but

the memory on the standby module does not add to the system’s capacity to store ﬂows.
