8800 Series Chassis Switch Hardware Installation Guide
Overview of the 8800 Series Chassis Switches
The switches are chassis-based, Ethernet service core switches designed for core
applications.
The features of these switches include:
• Hot-swappable I/O modules that include Gigabit Ethernet copper ports (10/100/1000) and
Gigabit Ethernet fiber ports (SFP), or 10 Gigabit Ethernet ports (SFP+ or XFP)
• Supervisory modules that provide the active switching fabric and CPU control subsystem
• Redundant, load-sharing, hot-swappable power supplies
• Field-replaceable, hot-swappable fan trays
• Auto-negotiation for half-duplex or full-duplex operation on 10/100/1000 Mbps ports
• Load sharing on multiple ports
The 8800 series switches include two chassis models:
• NETGEAR 8800 Series Chassis Switch XCM8806, with slots for installing one or two
Supervisory modules and up to five I/O modules
• NETGEAR 8800 Series Chassis Switch XCM8810, with slots for installing one or two
Supervisory modules and up to nine I/O modules
The modules for the 8800 series switches provide high port density and scalability for mid-sized
networks.
The specific capabilities of the switch are determined by the module series installed in the
chassis. For
more information about individual I/O modules and Supervisory modules, see
Chapter 2, 8800 Series Modules.
For more information about configuring a switch, see the NETGEAR 8800 Series Chassis Switch
User Manual and the NETGEAR 8800 Series Chassis Switch CLI Manual.
Full-Duplex Support
The switches provide full-duplex support for all ports. Full-duplex support means that frames
can be transmitted and received simultaneously, effectively doubling the bandwidth available
on a link. Most ports on a switch auto-negotiate duplex operation in the default configuration.
Gigabit Ethernet fiber ports and 10-Gigabit Ethernet ports operate only in full-duplex mode in
accordance with technical standards.
Management Ports
Each Supervisory module has a 10/100BASE-TX Ethernet management port. This port
allows you to communicate directly with the central processing unit (CPU) of the switch. You
can plug an Ethernet cable directly from your laptop into the management port for direct

Chapter 1. About the 8800 Series Chassis Switches |9
8800 Series Chassis Switch Hardware Installation Guide
access into the switch. This access allows you to view and locally manage the switch
configurations.
External Compact Flash Memory Card
Supervisory modules include a compact flash slot next to the console port. This slot accepts
a compact flash memory card, which can be used to download a new version of software and
for other functions, including capturing debug information and core dump files. See the
NETGEAR 8800 Series Chassis Switch User Manual for more information regarding the use
of the external compact flash memory card.
The external compact flash slot supports third-party compact flash cards.
Note: You have to use an industrial-grade compact flash card in the
external compact flash slot of the Supervisory module.

14 |Chapter 2. 8800 Series Modules
8800 Series Chassis Switch Hardware Installation Guide
Overview of the 8800 Series Modules
Supervisory modules and I/O modules are available. A module consists of a printed circuit
board mounted on a metal panel that acts as the insertion vehicle in the 8800 series
switches. The module carrier also includes ejector/injector levers and captive retaining
screws at each end of the module front panel. LEDs on the module front panel provide
information about the operating status of the modules.
The 8800 series switches support these modules:
• 8800 Series Supervisory Module XCM88S1
• 8800 Series 48-port 10/100/1000 Base-T Module XCM8848T
• 8800 Series 24-port 1000Base-X SFP Module XCM8824F
• 8800 Series 8-port 10GBase-XFP Module XCM8808X
Supervisory Module
The Supervisory module provides the active switching fabric and CPU control subsystem for
the switch. One Supervisory module is required for switch operation; however, adding a
second Supervisory module to the chassis increases reliability and throughput.
A compact flash slot allows you to insert an external compact flash memory card. (See
External Compact Flash Memory Card on page 9 for more information about supported
compact flash cards.)
Redundant Supervisory Module Activity
The 8800 series switches can run with a single Supervisory module installed. When you
install an additional Supervisory module, one Supervisory module operates as the primary
Supervisory module and the other becomes the backup (secondary) Supervisory module.
The primary Supervisory module is responsible for upper-layer protocol processing and
system management functions. Packet handling is distributed among the CPUs of all
installed Supervisory modules.
When you save the switch configuration, it is saved to all Supervisory modules.
Selection of the primary Supervisory module occurs automatically. The following examples
describe the selection process:
• When a switch boots with two Supervisory modules installed, the Supervisory module in
the lower-numbered slot becomes the primary Supervisory module. In the XCM8810
switch this is slot 5; in the XCM8806 switch, this is slot
3.
• When a switch boots with a single Supervisory module (regardless of the slot position), it
is selected as the primary Supervisory module.
If a second Supervisory module is added to the switch after it has been powered up, the
added Supervisory module becomes the backup Supervisory module. Supervisory

Chapter 2. 8800 Series Modules |15
8800 Series Chassis Switch Hardware Installation Guide
modules that operate as backup Supervisory modules can be inserted and removed
without disrupting network services.
• If you remove the primary Supervisory module while the switch is operating, the backup
Supervisory module performs a soft reset and then becomes the primary Supervisory
module.
For example, in an 8800 Series Chassis Switch XCM8810 with a primary Supervisory
module in slot 5 and a backup Supervisory module in slot 6, if you remove the primary
Supervisory module from slot 5, the backup Supervisory module in slot 6 becomes the
primary Supervisory module.
Supervisory Module Physical Features
The following figure shows the Supervisory module.
Figure 5. Supervisory module
The Supervisory module has the following features on the front panel:
• Module status LEDs
• Compact flash slot
• Console port. DB-9 serial port used to connect a terminal and perform local management.
• Management port. A 10/100 Mbps Ethernet management port used to connect an
Ethernet cable directly from your laptop to the switch to view and locally manage the
switch configurations. This port can also be used to connect the system into a parallel
management network for administration.

The Supervisory module has a slot for the XCM888F option card, which adds eight 1-gigabit
SFP data ports to the Supervisory module. These data ports operate the same as the ports
on the 24 G SFP module. (See 8800 Series 24-port 1000Base-X SFP Module XCM8824F on
page 19 for more information.)
Note: See the NETGEAR 8800 Series Chassis Switch User Manual and
the NETGEAR 8800 Series Chassis Switch CLI Manual for more
information about numbering conventions for the modules and ports,
as well as configuration and display information.

I/O Modules
The 8800 series of I/O modules consists of the following:
• 8800 Series 48-port 10/100/1000 Base-T Module XCM8848T on page 18
• 8800 Series 8-port 10GBase-XFP Module XCM8808X on page 19
• 8800 Series 24-port 1000Base-X SFP Module XCM8824F on page 19
No configuration information is stored on the I/O modules; all configuration information is
stored on the Supervisory modules.
When an 8800 series switch is powered on, the software generates a default configuration for
any slots that contain I/O modules. The default configuration allows the I/O module ports to
participate in the VLAN named default. The
default configuration for the I/O module is not
preserved unless you explicitly save the configuration to NVRAM.
You can configure parameters of an I/O module after it is installed, or preconfigure a slot for a
certain type of module and configuration. The preconfigured information is applied to the
module after it is inserted. If you preconfigure a slot for a specific module type and then insert
a different type of module, the inserted module does not become operational because of the
mismatch. If this situation occurs, the show slot command shows the module state as
mismatch.
Note: See the NETGEAR 8800 Series Chassis Switch User Manual and
the NETGEAR 8800 Series Chassis Switch CLI Manual for
feature-specific information related to XCM8000 series modules.
