IBM 8265: Product Description
The 8265 Controller Module (Feature Code 8000) monitors switch conditions and
reports failures to the Control Point and Switch module.
You can install an additional controller module to the switch for increased fault
tolerance.
For further details, refer to page 17.
Note: The Controller module must have a microcode level of 1.14 or higher to
operate in the 8265. If you are using an 8260 Controller Module, refer to the
IBM 8260 Nways ATM Control Point and Switch Module Installation and
User's Guide , SA33-0326 for information on upgrading the microcode.
The IBM 8265 Control Point and Switch (CPSW) module (Feature Code 6501)
contains a control program to perform the functions associated with the establishment
and management of ATM circuits. These functions are integrated into the switching
element of each CPSW module. As a result, the 8265 ATM subsystem uses a
distributed control system which offers the following advantages:
Each ATM module benefits from the fault-tolerant design of the IBM 8265 chassis.
•
Continued ATM network operation is ensured in case of a failure at a single point
•
in the network.
You can add a second CPSW module to the switch for backup purposes.
For further details, refer to page 18.
The PCMCIA cards contain 4MB of Flash EEPROM and contain the operational
microcode. The card fits into a type 3 PCMCIA slot on the CPSW module.
The following PCMCIA cards are available:
Base microcode with UNI and IISP functions.
•
The are two releases of the base microcode available:
– Release 1 (Feature Code 6505)
– Release 2 (Feature Code 6525) which includes support for OC 12 modules,
a port mirroring function, WAN statistics, counters per connection, and ILMI
4.0 support.
Enhanced microcode with UNI, IISP, and PNNI functions.
•
The are two releases of the enhanced microcode available:
– Release 1 (Feature Code 6506)
– Release 2 (Feature Code 6526) which includes support for OC 12 modules,
a port mirroring function, WAN statistics, counters per connection, and ILMI
4.0 support.
Note: 32 MB of RAM is required in the CPSW module to operate the enhanced
microcode (see page 14).
