8800 Modules - Avaya 8800 Installation Manual

Avaya Ethernet Routing Switch 8800/8600 module fundamentals
oversubscribed modules is cost-effective as long as the module provides strong built-in
packet QoS capabilities—R and RS modules both provide these capabilities.
• The 8612XLRS modules use a three-lane design based on RSP 2.6 architecture. The
8612XLRS is potentially 4:1 oversubscribed on all lanes.
• The 8634XGRS modules use a three-lane design based on RSP 2.6 architecture.
Potential 8634XGRS oversubscription is as follows:
- Lane 1 (RJ-45 and SFP): 1.6:1
- Lane 2 (RJ-45 and SFP): 1.6:1
- Lane 3 (XFP): 2:1
• The 8648GBRS modules use a three-lane design based on RSP 2.6 architecture. The
8648GBRS is potentially 1.6:1 oversubscribed on all lanes.

8800 modules

The 8800 series modules provide the same functionality as their RS module equivalents. The
8800 modules however, use the enhanced network processor — the RSP 2.7. R and RS
modules continue to be supported and you can install a mix of R, RS and 8800 modules in the
same chassis.
Important:
Support for 8800 series I/O modules starts with release 7.1. Support for the 8812XL,
however, starts with release 7.1.3. These modules are not backwards compatible with older
Ethernet Routing Switch 8800/8600 releases.
Important:
The following table shows the RS modules and the equivalent 8800 modules.

The 8692SF/CPU with the supermezz or the 8895SF/CPU are the supported switch fabric
modules in a chassis that contains 8800 series modules.
