Upgrading From The 8690Sf Or 8691Sf Module To The 8692Sf Module - Nortel 8600 Series Installing

68 Ethernet Routing Switch 8600 modules
Volume/0. If you want to use 40 MB on Volume/1, refer to the procedure
for upgrading the Flash memory to 40 MB in the Release Notes for the
Ethernet Routing Switch 8600 Software Release 4.1.
The 8692SF switch fabric enables a maximum forwarding throughput of
384 Mp/s, Using the Split MultiLink Trunking (SMLT) protocol in the core,
the Ethernet Routing Switch 8600 can provide over 1 Tb/s of core switching
capability.
You can install a 8692SF module in both slots 5 and 6 of the 8006, 8010, or
8010co chassis to enable redundant operation. The redundant module in
slot 6 can then assume the processing duties of a failing primary 8692SF
module in slot 5.
When the 8692SF module in slot 6 completes initialization, it recalculates
the topology (Layer 2 including STG, Layer 3 including routing topology
using RIP/OSPF or BGP) information for the switch unless you have
enabled the high-availability mode (HA-CPU flag). In that case all Layer 3
information (except multicast, IPX, BGP, and fast-VRRP) is synchronized to
the redundant CPU which results in no interruption of network services. For
more information about the high-availability mode, see Managing Platform
Operations.
The two 8692SF modules share switch fabric functions for the switch. If
one 8692SF module fails, the system reverts to operation with a single
8692SF module.

Upgrading from the 8690SF or 8691SF module to the 8692SF module

If you have two Ethernet Routing Switch 8690SF modules or two 8691SF
modules installed in your Ethernet Routing Switch 8000 Series chassis
you can upgrade to the Ethernet Routing Switch 8692SF module with a
minimum loss of traffic.

CAUTION
Do not install a software version earlier than Release 3.5.6 on
the 8692SF module. Operating the 8692SF module with any
release below Ethernet Routing Switch 8600 Software Release
3.5.6 damages this module.
CAUTION
Before inserting an 8692SF in a secondary CPU slot, make sure
that the primary CPU is already running Ethernet Routing Switch
8600 Software Release 4.1.
