Main Components
Front View
Toggle Power Switch
This switch toggles power on and off. To power off, the switch must be pressed
and held for 5 seconds.
Reset Button
Press and release the reset button to reset the WebMux™. This process may
take several minutes to complete.
Up Arrow Button, Down Arrow Button
When each button is pressed, the value on the cursor location increases or
decreases. It goes through lower case letters, upper case letters, numbers and
symbols. When the cursor is located at the left most position on the LCD, the up
and down arrow allows the user to select a different item to setup.
Left Arrow Button and Right Arrow Button
When each button is pressed, the cursor moves to the left and right.
Check Mark Button, and Cross Button
Check Mark Button confirms the selection, Cross Button cancels the selection. At
any time when the system is running holding down to the Check Mark Button will
invoke the configuration menu, where you can change IP addresses and other
settings.

Server LAN Port
Connect this port to the Server LAN switch or hub. This port connects to the
servers and your local computers. It is the right most RJ45 socket. In Out-of Path
configuration, this is the only Ethernet cable to be connected.
Backup WebMux™ Port
Optionally, you may connect another WebMux™ to this port so that you can have
redundancy. If you have more than one WebMux™, you can connect them using
a cross over cable, or a regular cable with a hub.
Router LAN Port
Connect this port to the Router LAN switch or hub. In most situations, this port
connects to the Internet side network in NAT mode. It is the left most RJ45
Socket.
PLEASE NOTE: The Router LAN and Server LAN port are not interchangeable.
External Modem Connect Port
To utilize the phone pager function of the WebMux™, please connect the
external modem to this port. In some cases, if you prefer support engineers to
not use diagnostic ports over the Internet, our support engineers can also
connect through the modem to assist you with setup issues. A US Robotics
V.Everything modem is required: US Robotics part number 3CP3453. Modem dip
switch has 3, 8, and 10 down, rest up. A standard external modem cable is also
needed. Check with your modem supplier for the cable.
Power Switch
This switches the WebMux™ on and off. When in the "off" position, the front
panel power switch is disabled.
Power Cord
Please use the supplied power cord to connect the WebMux™ to the power
source. 1U WebMux™ has a 115V/230V AC universal power supply.

WebMux™ Overview
Key Features
The WebMux™ is a standalone network appliance designed primarily to load
balance IP traffic to multiple servers. The WebMux™ includes the following key
features.
•Improves performance by distributing the traffic for a site or domain
among multiple servers. No one server will be bogged down trying to
service a particular site.
•SSL Termination to reduce the cost of multiple certificates.
•Provides high availability by tracking which servers are functioning
properly and which servers are out of service. If a server unexpectedly
goes down, the WebMux™ will automatically re-direct the traffic to other
servers, or will bring a standby or backup server online to service the
traffic. The WebMux™ does application level health check to many
network protocols on servers.
•Provides Persistent Connections by memorizing the user browser
session and the server session and sending the same user to the same
server. This is important for sites using shopping cart and dynamically
generated pages, like BroadVision, ASP and JSP sites.
•Provides fault tolerance. This installation requires two WebMuxes, a
primary and a secondary. The two WebMuxes will automatically sync the
configuration datum.
•Easy management. It can be managed via a secured web browser
session from anywhere in the world. By using https 128 bit encryption to
the management web console, secure remote management of server
farms is truly possible.
•Operating System independent. No software or agent to load on the
servers. Non-intrusive load/failure detection and management.
•Provides Proxy function. When communication is initiated from behind
the WebMux™, the WebMux™ will substitute its own address for the
internal address. This allows the web servers to initiate communication for

services such as credit card validation and mapping services. (Note: this
function only works in NAT mode).
•Built-in Firewall Protections. Stop possible hacker intrusion into your
network from Internet. All IP addresses and ports are blocked except the
farm IP address. Built-in functions will detect any possible denial of service
attack and make your services always available. (Note: this function only
works in NAT mode with “Forwarding Deny”, see setup for details).
•In-Path or Out-of-Path Load Balancing. In normal setup, the WebMux™
can be configured In-Path, to act as firewall in addition to the load balancer
and health checker. However, if outbound traffic is much larger than
inbound traffic and you already have a firewall in place, or change of IP
address causes problems, consider using Out-of-Path configuration. Out-
of-Path load balancing is also called direct routing, or one leg operation.
•Layer 7 Load Balancing. WebMux™ can direct traffic to specific groups
of servers within a farm according to a match pattern in HTTP MIME
header. This allows you, for example, to group servers that serve only a
specific type of content while serving other types of content on another
group of servers. WebMux™ Layer 7 load balancing also includes URI
load directing with host name MIME header matching and cookies in order
to memorize the user browser session and the server session and send the
same user to the same server. This is important for sites using shopping
cart and dynamically generated pages.
•Informs you of the status of your network. It provides phone pager
and email notification so that the network administrator can be paged or
emailed whenever a server or WebMux™ goes down, and when it returns
online. This feature could reduce server room night shift operator costs, or
timely repair should the server goes down unexpectedly.
