Add 2.5 W for each XFP
For example, if you use two 10GBASE-ER XFPs in a 8612XLRS module
that is otherwise filled with 10BASE-SR XFPs, add 2*1.5 W to the 257.9 W
for a total of 260.9 W.
You can also calculate chassis and module power consumption using the
Power Management Calculator (Nortel ERS8600 Power Management
Calculator), available on the Nortel Technical Support Web site. You can
find the calculator at www.nortel.com/documentation. Choose Routers &
Routing Switches, and then Ethernet Routing Switch 8600.
The following table provides power consumptions specifications for SFPs
and XFPs.

SF/CPU modules
The following sections describe the Switch Fabric/Central Processing Unit
(SF/CPU) modules.
8691 SF/CPU module
The 8691 SF/CPU module provides the core switching fabric for the
Ethernet Routing Switch 8600, as well as a CPU subsystem and a
real-time clock (see the following figure). The core switching fabric
switches all traffic through the routing switch modules. The CPU
subsystem manages the routing switch fabric and the other interface
modules.
