Xedge Hardware Overview
Chapter 1:
Introduction
This chapter provides an overview of the major hardware components in an Xedge 6000 system.
An Xedge switch is comprised of slot controller modules and line interface modules (LIMs) in a
compatible chassis, controlled by Xedge switch code. The operational capabilities of a particular
switch are defined by the chassis type, the type of slot controllers installed, the LIMs in use by slot
controllers, and the type of switch fabric in use, if any. This section provides brief descriptions of
these major components.
Identifying Xedge Modules
It is necessary to correctly identify the type and revision level of each
Xedge module in order to properly install and configure those modules in
your Xedge switch. An abbreviated product name is printed on the front
panel of each module. Some identifying information is also located on the
Product Identification label affixed to each module.
To locate the Product ID Label on an Xedge module:
•
For a slot controller or switch fabric:
With component side up and front panel to the left, the
Product ID label is at the top-right corner of the module.
•
For a LIM:
With component side up and front panel to the right, the
Product ID label is at the lower-left corner of the module.
•
For an LPM:
The type of LIM Personality Module on your packet slot controller can be identified via
the terminal interface (M,0).
Note
When handling modules, always use an antistatic wrist strap to prevent static discharge damage to circuitry.
Xedge Software Versions
Each slot controller has an independent SNMP agent configured with MIBs appropriate to its
function. The Xedge operating software (XOS) is stored in flash EPROM of the module, allowing
for the download of new operating code for enhancements, new features and updated standards.
An Xedge switch can function with more than one type of slot controller installed.
•
If your switch contains legacy Xedge cell controllers or adaptation controllers in ATM
applications, those devices and their LIMs are controlled by Version 6.2 switch code.
•
If your switch contains packet controllers in multiservice packet exchange applications,
those devices and their LIMs are controlled by Version 7.x switch code.
•
If your switch contains a mix of packet and legacy controllers, the slot-0 controller must
be a packet controller.
All Xedge software is pre-loaded at the factory. When you need to upgrade Xedge software in a
controller/LIM, or install new modules in an exisiting switch, refer to the detailed procedures
provided in the software release and patch notes for that specific controller.
