Connect the Switch to the Network
To connect the switch physically to your network, connect the cables according to the
instructions in the installation guide. See the ProSafe® 24-Port Gigabit L2 Managed Switch
Installation Guide for complete steps. A PDF of the installation guide is on the NETGEAR
support website.
Switch Management Methods
The switch functions as a simple switch without the management software . However , you can
use the management software to configure more advanced features that can improve switch
efficiency and overall network performance.
You can use one of the following management functions to configure an
eb management interface (see Configure Access to the Web Management Interface on

d monitor the switch:
Introduction and Getting St arted

ProSafe 24-Port Gigabit L2 Managed Switch JGSM7224
Note: To configure the switch by using SNMP or RMON, you first need to
configure these functions on the switch through accessing the web
management interface or CLI.
The first three of these standards-based management methods let you both configure and
monitor the components of the switch. The fourth method lets you monitor the component s of
the switch only . The method that you use to manage and monitor the switch depends on your
network size and requirements, and on your preference.
Configure Access to the Web Management Interface
The web management interface lets you monitor, configure, and control the switch remotely
using a standard web browser so you do not have to use SNMP software products. From
your web browser, you can monitor the performance of your switch and optimize its
configuration for your network. You can configure all switch features, such as VLANs, QoS,
and ACLs by using the web management interface.
Before you can access the web management interface from a computer, you need to
configure t
whether there is a DHCP server in the network, follow one of the procedures that are
described in the following sections:
• Configure Access When the Switch Functions in DHCP Client Mode without a DHCP
Server on
• Configure Access When the Switch Functions

• Configure the Switch with a Static IP Address on p

Configure Access When the Switch Functions in DHCP Client Mode without a DHCP Server
If there is no DHCP server in your network, the switch assumes a default IP address of
169.254.100.100 and subnet mask of 255.255.0.0. Use this IP address and subnet mask to
log in to the switch (see Log In to the Web Management Interface on

eeds to be in the same subnet as the default IP address on the switch. For most networks,
this means that you need to change the IP address of the computer to be on the same subnet
as the default IP address (169.254.100.100) of the switch. For example, configure the
computer with IP address 169.254.100.80 and subnet mask 255.255.0.0.
page 17).
To change the IP address on a computer that is run
system, open the Internet Protocol (TCP/IP) Properties screen that you can access from the
Local Area Connection Properties screen, as shown in the following figure. You need
Windows administrator privileges to change these settings.

WARNING:
Figure 4.
When you change the IP address of your administrative system,
you lose your connection to the network. Write down your current
network address settings before you change them.
To modify the network settings on your management computer:
1. On
a computer that is running a Microsoft Windows operating system, open the Internet
Protocol (TCP/IP) Properties screen.
2. Set
the IP address of the administrative system to an address in the 169.254.100.0 network,
such as 169.254.100.80. The IP address needs to be different from that of the switch but
within the same subnet.
3. Click OK.
For information about how to log in to the switch, see Log In to the Web Management
Interface o
n page 17.
Configure Access When the Switch Functions in DHCP Client Mode with a DHCP Server
By default, the switch is configured as a DHCP client to obtain its IP address from a DHCP
server in the network. You need to access the switch from the console port.

Configure the Switch with a Static IP Address
If the network has no DHCP service, you need to assign a static IP address to the switch. If
you prefer, you can also assign a static IP address to the switch even if the network has
DHCP service.
To access the switch from the console port to assign a static IP address:
1. Con
nect a console to the switch. Using the null-modem cable supplied with the switch,
connect a VT100/ANSI terminal or workstation to console port of the switch (see

Interface Naming Conventions
The switch supports physical and logical interfaces. The logical interfaces are link
aggregation groups (LAGs), also referred to as port channels. Interfaces are identified by
their type and the interface number. The physical ports are Gigabit interfaces and are
numbered on the front panel. You configure the logical interfaces by using the web
management interface or CLI. The following table describes the naming conventions for
these interfaces:
