Chapter 2 Processor Cards Feature Summary
System Processing Engine Card
System redundancy is highly recommended. You can easily build in redundancy
by adding SPEs for additional call-processing capabilities. For recovery, you
should regularly perform a backup of all applications installed on the SPE, using
the backup mechanisms that are recommended in the documentation for each
application.
Note
SPE200 cards that were used prior to system software release 2.1.0 are now
obsolete. If you have a system with SPE200 cards and wish to install and use
system software release 2.1.0 or later, you must replace the SPE200 cards with
SPE310 cards. The SPE310 offers a keyboard and mouse port, a video port, and
two universal serial bus (USB) ports supporting standard USB devices such as
pointing devices and CD-ROM drives. The keyboard and mouse port can be used
to connect simultaneously to a keyboard and a mouse, using the Y-cable that is
included with the hardware. These SPE310 ports are required for
Cisco CallManager installation and upgrades on the Cisco ICS 7750, beginning
with system software release 2.1.0.
Figure 2-2
shows the SPE310 card.
