Introduction
This document describes how to upgrade the network interface cards (NICs)
on a Webwasher appliance, using a special type of Gbit network interface card
with six ports on it.
You can do an upgrade with one or two cards, depending on the appliance
model, see below.
The upcoming sections provide information about the number of additional
ports that will be available after the upgrade for each of the various appliance
models, see Chapter 2.
Furthermore, the upgrade procedure is described, see Chapter 3.
Finally, it is shown how the interface numbering was affected when new net-
workinterfacecardswereinstalledonthevariousappliancemodels,seeChap-
ter 4.

Chapter 2
Additional Ports
Depending on the appliance model, you can just insert the network interface
card mentioned above in a free slot or replace one or two of the existing cards,
thus increasing the number of ports in different ways:
•WW500
The WW500 Appliance is equipped with two onboard network interfaces,
each of them providing one port.
By inserting a network interface card with six ports in a free slot, you can
increase the total number of ports to eight:
2+6=8
•WW1100
The WW1100 Appliance is equipped with two onboard network interfaces,
each of them providing one port. One of these ports is a Dual Port. Fur-
thermore, there is a network interface card, providing two ports.
You canreplace the latter by a card with six ports, which increases the total
number of ports to eight:
2+(2–2+6)=8
•WW1900
The WW1900 Appliance is equipped with two onboard network interfaces
and two network interface cards, each of them providing one port.
You can replace one of the network interface cards by a card with six ports,
which increases the total number of ports to nine, or replace both network
interface cards by cards with six ports, thus increasing the total number of
ports to 14:
2+1+(1–1+6)=9
or:
2+(1–1+6)+(1–1+6)=14
2–1

Additional Ports
•WW2900
The WW2900 Appliance is equipped with two onboard network interfaces
and one additional network interface card, providing two ports.
You can insert another card with six ports in one of the two free slots that
are providedfor this purpose, which increases the number of ports to 10, or
insert a card in each of the slots, thus increasing the total number of ports
to 16:
2+2+6=10
or:
2+2+6+6=16

Upgrade Procedure
To complete the upgrade procedure for the network interface cards on your
Webwasher appliance, proceed as follows:
1. Power down the appliance and unplug the power cord.
2. Open the appliance cover.
Note: As always, observe the usual ESD (Electro Static Discharge) pro-
cedures when handling network interface cards.
3. Install the network interface card or cards on the appliance. To do this,
proceed according to the appliance model in question:
•WW500
Insert the new network interface card in the free slot provided for this
purpose on the rear side of the appliance box.
The following diagram shows the rear panel of a WW500 appliance
box. On the right side of this panel, there are two free slots for in-
stalling additional devices. Use the upper slot to install the additional
network interface card:
Note, however, that the slot positions may vary according to the par-
ticular version of the appliance model in question.
For a complete description of the elements on the rear side of the
WW500 Appliance, see the Rear Side subsection of section 2.1 in
the Installation and Configuration Guide, Webwasher Appliances.
3–1

Upgrade Procedure
•WW1100
Remove the network interface card that is already installed in one of
the NIC slots on the rear side of the appliance, and insert the new
network interface card instead.
The following diagram shows the positions of these slots (9 and 10):
Note, however, that the slot positions may vary according to the par-
ticular version of the appliance model in question.
For a complete description of the elements on the rear side of the
WW1100 Appliance, the Rear Side subsection of section 2.3 in the
Installation and Configuration Guide, Webwasher Appliances..
•WW1900
Upgrading one network interface card – Remove one of the two
network interface cards that are already installed when the appliance
is shipped, and insert the new network interface card instead.
The following diagram shows the positions of the network interface
slots (2, 6, 7, and 8) on the rear side of a WW1900 Appliance:
Note, however, that the slot positions may vary according to the par-
ticular version of the appliance model in question.
Of the slots shown in the diagram, only the upper two (2 and 8) can
be used for removing and replacing network interface cards since the
lower slots belong to the appliance mainboard.

Upgrade Procedure
Furthermore, it is recommended that you remove and replace the net-
work interface card located in the upper right slot if you just want to
exchange one card.
For a complete description of the elements on the rear side of the
WW1900 Appliance, the Rear Side subsection of section 2.4 in the
Installation and Configuration Guide, Webwasher Appliances.
Upgrading two network interface cards – Remove both network
interface cards that are already installed when the appliance is
shipped, and insert the two new network interface cards instead.
•WW2900
Adding one network interface card – Insert the new network inter-
face card in one of the two free slots on the rear side of the appliance.
It is recommended that you use the upper of the two slots for this
purpose.
Adding two network interface cards – Insert a new network inter-
face cardin each of thetwo free slots on the rearside of the appliance.
4. Close the appliance cover.
5. Attach a keyboard and monitor directly to the appliance.
6. Plug in the power cords for appliance and monitor.
7. Power on the appliance.
8. Boot the appliance.
9. Because the interfaces may have renumbered during the reboot, verify
your cabling and connectivity by doing the following:
a. Log into the system using the keyboard and monitor.
b. Use the ifconfig -a command to get the interface’s information.
Write down the interface name, e. g. eth0, IP address, and net-
mask for each interface. Also note if the interfaces are enabled.
Note: If an interface is notenabled, then itmay not beenabledinthe
GUI, there may not be a cable in the corresponding port, the cable
may not work, or the device at the other end may not work. Follow
standard troubleshooting techniques to resolve the problem.
c. Verifythateach cableallows connectionto themachinethat matches
its intended subnet and netmask. Once everything is cabled cor-
rectly, ping the IP address of each neighboring machine. If you re-
ceive a response, your interface configuration and cabling is correct.
d. If you do not receive a response and you have verified the other
factors listed above, then your interfaces and your cables are not
properly matched. Swap the cables until each port connects to the
expected network.
