Hardware fundamentals and guidelines

Modules

Use modules to interface the switch to the network. This section discusses design guidelines
and considerations for Avaya Ethernet Routing Switch 8800/8600 modules.

SF/CPU modules

The switch fabric/CPU (SF/CPU) module performs intelligent switching and routing. Every
chassis must have at least one SF/CPU; for redundancy, install two SF/CPUs.
Release 7.0 supports only the 8895 SF/CPU and the 8692 SF/CPU with SuperMezz. The 8692
SF/CPU must be equipped with the Enterprise Enhanced CPU Daughter Card (SuperMezz)
for proper functioning with Release 7.0 and later. The 8895 SF/CPU has SuperMezz
capabilities built into the module, and so does not support a SuperMezz card.
The use of dual 8692 SF/CPU or 8895 SF/CPU modules enables a maximum switch bandwidth
of 512 Gbit/s. Dual modules provide redundancy and load sharing between the modules. Split
MultiLink Trunking (SMLT) in the core in a resilient cluster configuration (redundant switch with
two 8692 or 8895 SF/CPU modules) can provide over 1 terabit per second (Tbit/s) of core
switching capacity.
You can install the 8692 or 8895 SF/CPU module in slots 5 or 6 of the 8006, 8010, or 8010co
chassis. The 8692 and 8895 SF/CPU modules are supported in slot 3 of the 8003-R chassis.
With dual SF/CPUs, you must install the same type of SF/CPU in both slots. You cannot install
one type of SF/CPU in one slot, and a different type in the other slot. For example, you cannot
install the 8692 SF/CPU in one slot and the 8895 SF/CPU in the other.

RS module

RS modules include the 8648GTRS, the 8612XLRS, the 8634XGRS, and the 8648GBRS. RS
modules provide support for a variety of technologies, interfaces, and feature sets and provide
10 Gbit/s port rates. RS modules require the high-speed cooling module and the 8895 SF/
CPU or 8692 SF/CPU with SuperMezz.
In chassis equipped with RS modules, you can use 8005AC, 8005DI AC, 8004AC, or 8004DC
power supplies. RS modules are interoperable with R modules.
The following figure shows typical uses for RS modules.
