10BaseT LED indicator This LED will glow green if the 10/100BaseTX

connector is using 10BaseT.

Front Panel

The Instant GigaDrive’s front panel (shown below) displays the majority of
the drive’s status lights.

System Green. Normally on.
If this light shines a steady green, then the Instant

GigaDrive is working properly. It blinks during
Startup or Shutdown, and turns off after the shut­down is completed. It will blink during a software
upgrade.

Status Red. Normally off.
If this light is turned on, then there is a hardware

error. It will also be on during the power-on self
test. Once the self-test is completed, it should turn
off. It will blink during a software upgrade.

HD Green
Flashes when the GigaDrive’s hard drive is being

accessed. Stays on during the self-test.

LAN Green
Flashes when data is transmitted or received via the

network.

IP Amber
If this light it turned on, the GigaDrive is acting

as a DHCP client and receiving an IP address from
a DHCP server on the network. If this LED is
fl ashing, no DHCP server responded to the client
request.

Basic Installation
& Setup

The following section instructs you on how to physi­cally connect the Instant GigaDrive to the network,
and how to confi gure the Instant GigaDrive for basic
operation in your Windows environment. Everything
you need to do to get your Instant GigaDrive up and
running is covered here.

This section also covers the hook-up of a printer on the GigaDrive’s printer
server port. Please note, however, that the GigaDriv e will perform equally well
as a storage device with or without an attached printer. If you aren’t interested
in taking advantage of the Instant GigaDrive’s printer server function, skip any
steps that deal with printer installation. The GigaDrive’s installation process
will work fi ne without them.

Connecting Everything Together and Booting Up

Requirements

network administrator,
please follow these
Basic Installation &
Setup steps, then con­tinue on to the Admin­istration section which
follows. There you will
fi nd the full available
range of administrator
options.

The following conditions are required to begin the installation of the Instant
GigaDrive to your system.

• TCP/IP protocol.

• If connecting to a network, an available port on a hub or switch.

• If connecting to a PC, an installed and available Ethernet or Fast Ethernet

port.

Hardware Installation

If the above conditions are met, follow the steps below to begin the installation
of your Instant GigaDrive.

1. Connect the network cable to the Instant GigaDrive. Locate the RJ45

network cable that came packaged with your Instant GigaDrive. Plug it into
the RJ45 socket on the GigaDrive’s rear panel.

2. Connect the Instant GigaDrive to your hub, switch, or PC. If you plan to

connect the GigaDrive to the network through a hub or switch, be sure that
the uplink button on the rear panel of the GigaDrive is depressed, then plug
the other end of the RJ45 cable into one of the ports on your hub or switch.
If you want to connect the GigaDrive directly to a PC, make sure that the
uplink button is in the up position, and connect the RJ45 cable directly into
the PC’s network card.

3. Connect a printer to the Instant GigaDrive. Connect a standard printer

cable to the GigaDrive’s rear-panel printer port. Connect the other end of
the cable to your printer.

4. Connect the power supply. Plug the supplied power adapter into the

GigaDrive’s power input port, located on the GigaDrive’s rear panel. Con­nect the other end of the power adapter to a power outlet.

5. Power on. Locate the GigaDrive’s power switch on the upper left of the

GigaDrive’s rear panel. Press it once to power on the GigaDrive.

6. The GigaDrive’s self-test. Now that its power is on, the GigaDrive’s boot

process will begin. The GigaDrive will run a brief self-test (2 or 3 seconds)
prior to actually booting up. During the self-test, all of the GigaDrive’s
LEDs will be illuminated or fl ashing.

7

7. Booting up. When the self-test is complete, most of the LEDs will turn

off. The System LED will blink continuously, and the LAN LED will blink
occassionally. This signifi es that the GigaDrive is in the actual process
of booting up. Boot up should take approximately 1-3 minutes. It will
take longer on the fi rst bootup, and on any bootup following an improper
shutdown.

8. Boot up completed. When most of the LEDs turn off, leaving only the

System LED illuminated (and not blinking), the GigaDrive’s boot up is

complete. If the Status LED stays on, or if the GigaDrive repeatedly beeps,
there is a hardware problem. Consult this user guide’s Troubleshooting
section (page 29) or Appendix entry on the GigaDrive’s buzzer (page 32)
for possible solutions.

Confi guring Your Instant GigaDrive

Now that everything is connected and powered on, you
are ready to confi gure your Instant GigaDrive so that it
is accessible to the users on your system. You will have
to install the Instant GigaDrive Utility on your PC to
access the GigaDrive’s Quick Setup feature.

Instant GigaDrive Utility Installation

The Instant GigaDrive Utility is a simple piece of soft­ware which assists in the quick and easy setup of your
GigaDrive, and helps to keep up on the GigaDrive’s
status and settings. To install the Utility to your Win­dows 95, Windows 98, or Windows NT 4.0 system,
follow the instructions below.

Note: Linksys does
not support Beta
operating systems.
While the Instant
GigaDrive and its
Utility may very well
work in future ver­sions of Windows,
Linksys will offer no
technical support for
such a system until
it’s offi cially
released by Micro­soft. At that time,
support will become
available on Link­sys’s web site —
www.linksys.com.

1. Insert the CD-ROM. A CD-ROM should be sup-

plied in your Instant GigaDrive packaging. Insert the CD into your PC’s
CD-ROM drive.

Instant GigaDrive Utility

The column on the left side of the Utility’s main screen displays a list of all the
Instant GigaDrives on your network. The status box on the right displays data

about the currently-selected Instant GigaDrive. If no GigaDrives are listed, see
this manual’s Troubleshooting section.

10

Quick Setup

Button

In the left column of the Utility screen, highlight the Instant
GigaDrive you are confi guring and click the Quick Setup

button (shown) on the far left of the tool bar. The Setup
screen will be displayed, as seen below.

Quick Setup

The Instant GigaDrive Utility’s Quick Setup displays the settings you need
to get your GigaDrive on the network and running smoothly. You can come
back and change this information at any time, but right now you need to check
each category to confi rm that your current GigaDrive
settings are properly confi gured for your system.

Server Name The Server Name is the name by
which the Instant GigaDrive will be identifi ed in

your network environment. The current name, which
is likely a series of letters and numbers, is your
GigaDrive’s default name. You can change the name
from anything to GigaDrive, to Disk Server, to Bob.
Changing the name will not in any way effect the

Date/Time Ensure that the date and the time are correct.

Obtain an IP Address Automatically (DHCP Client) If you have a DHCP
or Bootp server on your Network, you can choose this setting, which will
enable the GigaDrive to accept an IP address at startup. Because the Instant

GigaDrive is a server, however, it is recommended that you assign it a fi xed
IP. If your network doesn’t have a DHCP server, then you must set a Fixed
IP Address.

Fixed IP Address Select this option if you wish to select a static IP address
for the Instant GigaDrive. This option is required if you wish to take advantage
of the Instant GigaDrive’s DHCP Server function.

IP Address If you selected Obtain an IP Address Automatically, then these
boxes will be greyed out and inaccessible. If you chose to set a fi xed IP

Address for your GigaDrive, enter into these boxes a free IP Address from the
address range used by your networked PCs. The default IP value assigned to
your GigaDrive on its fi rst installation is 192.168.0.2. If you do enter a fi xed IP
address, be sure to make a note of it for future reference.

Network Mask Be sure that this address matches the Network or Subnet

Mask number assigned to the other PCs on your network. The default Instant
GigaDrive value is 255.255.255.0.

Gateway Again, use the same value here as the value assigned to the PCs
on your network. If you don’t have a router or Internet Gateway, leave this
value blank.

Enable DHCP Server If checked, the Instant GigaDrive will act as a DHCP

Server. It will provide an IP Address and related data to a networked PC at the
PC’s request. PCs will request an IP address only if they are set to act as DHCP
clients. (See the Windows Client Setup section on page 23 of this user guide
for more details and instructions.)

Start IP Address/Finish IP Address You will only need to fi ll in these values
if the Instant GigaDrive is confi gured to act as a DHCP server. The Start IP

Address number should be the fi rst value in the range of IP Addresses you
would allow the GigaDrive to assign to a DHCP Client. The Finish IP address
should be the fi nal value in that range. Ensure that this range of IP addresses is
large enough to cover all of your DHCP clients (PCs and other devices making
DHCP requests.).

12

Microsoft Networking Workgroup Name This name should match the
Workgroup name used by the PCs on your network. The default is set to
“workgroup”.

Apple Networking For your convenience, the Instant GigaDrive is Apple-
compatible. Linksys, however, offers no support for setup under Macintosh
operating systems.

Completing the GigaDrive’s Quick Setup

When you have entered all of the Quick Setup values, click OK to save the
values and to exit. The Instant GigaDrive is now operational. All W indo ws
users have been given Guest access rights. They can now access the Giga-
Drive’s printer and its public folder.

To create multiple user groups and shared directories on the Instant GigaDrive,
use the Browser-based Administration interface. This is invoked with the
Administration icon on the Instant GigaDrive Utility’s main screen. The fol-
lowing section of this User Guide deals with the Instant GigaDrive’s Adminis-
tration interface and options.

Administration

Overview of Administrative Options

There are four organizational entities that can be created on the Instant Giga­Drive in order to manage and allocate the GigaDrive’s storage space.

Administrators The administrator controls Instant GigaDrive disk-space allo-
cation by creating users, groups, and shares. The administrator can then
coordinate which users fall into which groups, and which groups can access
which shares. The administrator (and any other administrators who may be
added in the future), has full read-write access to all shares.

Users Each user is identifi ed by his user name and password. The administra-
tor creates users, and can also limit the amount of disk space available to a
user.

Groups Users are organized into user groups. Groups are created in order to
allocate which users have access to which shares.

Shares A share is a folder or directory that has been saved onto the Instant
GigaDrive’s hard drive. Shares are generally created to reserve disk space
for specifi c groups. Only the Instant
GigaDrive administrator can create a
share, but users who have access to
that share can create other folders or
directories within that share. Shares
can be created as read-only or read­write, depending on need and share
content. Each share can be accessed
by only one group, but each group can
access many shares.

Guest Users Besides administra­tors, regular users, and groups, guest
users may also access the Instant
GigaDrive. The guest user has Read/
Write access to the public share. This
can be changed, and access to addi­tional shares can be granted. Anyone
on the network who does not have a
user name on the GigaDrive is auto­matically logged in as a guest.

13

The Web-based Administrative Interface

Because the Instant GigaDrive doesn’t have an attached keyboard or monitor,
you have been provided access to the GigaDrive’s internal data and processes

through your web browser. The GigaDrive contains an HTTP server which
enables you to connect and confi gure your GigaDrive using Netscape 4.04
or better or Internet Explorer 4.0 or better. This connection can be made

14

with a click of the GigaDrive Utility’s Administration Button,
or through entering a URL into any networked PC’s web
browser.

Accessing the Administration Interface with the Instant
GigaDrive Utility

Administration

Button

Run the Instant GigaDrive Utility. After the Utility searches your network
and locates all of your Instant GigaDrives, click the Utility’s Administration
button (as seen to the above right). You will be prompted for your username
and password. Enter “admin” for the user name.

By default, there is no password. Unless you have already changed the
password for “admin” in the Instant GigaDrive Utility, leave the Password
window blank and click OK. You will be brought to the Welcome screen.

Choose the GigaDrive you wish to access. Choose Connect. Click the
Administration button. The Administrative Menu page will load.

Accessing the Administration Interface With Only Your Web Browser

If you are working on a networked PC without an installed version of the
Instant GigaDrive Utility, you can still access the
Administration Interface through your web browser.

Start your web browser. In the Address box, enter the
following web address:
http://IP Address, where the IP Address is

Note: You will need
the IP address of the
GigaDrive on hand in
order to gain access
to the Interface.

the IP Address of the Instant GigaDrive you wish to
confi gure (or try http://ip_address/CGI_main/index.htm.)

This will bring you to the password prompt described above. Follow the
directions from there to reach the Administrative Menu.

15

The Administrative Menu - Confi guration

The options on the Administrative Menu are divided between two categories—
Confi guration and Storage Management. Confi guration deals mostly with the
setup and monitoring of the Instant GigaDrive’s network and system variables.

Administrative Menu

The Administrative confi guration options are listed on the following page.

16

Network

The Network options, which are also found
in the Quick Setup area of the Instant Giga­Drive Utility, allow you to confi gure the
following variables.

Note: NEVER shut­down the Instant
GigaDrive by cut­ting off its power
supply.

• IP Address Set the IP Address, Network

mask (Subnet Mask), and Gateway variables.

• DHCP Enable and confi gure the DHCP Server function.

• DNS Set the Domain Name Server IP Addresses.

• AppleTalk Set the AppleTalk Zone. The default value is “*”,

which allows access by all zones. Linksys does not provide
technical support for the Macintosh operating system.

• Microsoft Confi gure Microsoft networking, and set the Work-

group Name and Code Page (alphabet).

System

• General Set the Instant GigaDrive name, date and time.

• E-mail Confi gure the Instant GigaDrive to send E-Mail mes-

sages if there is a problem.

• Printer Port Confi gure the printer. This is helpful but not

essential for Windows users.

• Shutdown Shutdown the Instant GigaDrive, or create a shut-

down schedule.

Utilities

These utilities are not required for normal operation. They are
tools to help you better manage the GigaDrive.

• Disk Check the disk for errors. (Similar to Scandisk.) Because

the disk check takes an exceptionally long time, this should be
done overnight.

• Log Check the system log. This is provided only for trouble-

shooting.

• Upgrade Upgrade the Instant GigaDrive’s software.

Status

• Disk Check disk usage. This data is read-only.

• Printer Check the printer status, and delete the current print

job, or all print jobs.

• System Check System status. This data is read-only.

The Administrative Menu - Storage Management

The Storage Management options manage the Instant GigaDrive’s shares,
users, and groups. This section is only meant as a brief introduction. The
following section, Managing Shares, Groups and Users, expands on what you
will read here.

Groups

Groups are collections of users created to manage access to
shares.

• View the current groups, modify their shares access, and add or
remove users from a group.

• Create new groups, or delete existing
groups.

Shares

Shares are folders placed on the Giga-

Drive. Access to each share can be moni-
tored by an administrator.

• Create, delete and modify shares.

Note:
We recommend that
you browse the
shares and folders
on the Instant Giga­Drive to view the
relationships
between them, and
to view the Giga­Drive’s directory struc­ture.

17

Users

• View the list of existing users, and modify individual user data.

• Create or delete individual users.

18

Managing Shares, Groups, and Users

By creating shares, groups, and users on the Instant GigaDrive, the Administra­tor is able to allocate how much GigaDrive space is available to each person
working over the network.

Quick Terminology

• User A user can be thought of as a single account on the GigaDrive. A

user, which is basically a name with a password, is most typically created
on the GigaDrive to defi ne a specifi c networked person’s GigaDrive access
rights.

• Group A group is a collection of users. Groups are created to more easily

manage users’ access to shares. Each individual user can belong to many
groups.

• Share A share is a directory folder created on the Instant GigaDrive. Access

to a share is given to a group by an administrator. Each share can only be
accessed by a single group.

• Access Rights All shares are confi gured with specifi c access rights – either

Read Only or Read/Write.

Pre-con• gure• Users, Groups, an• Shares

On initial setup, the Instant GigaDrive already has the following shares, groups
and users installed. These pre-defi ned objects cannot be deleted, and only
limited modifi cations may be performed

Users admin
The admin user is a member of the administrator group, and

therefore has Read/Write access to all shares. By default, the
admin user has no password, but a password can be assigned
by the GigaDrive Administrator. Assigning a password is recom­mended. This user can not be deleted.

guest
The guest user is a member of the everyone group, and may be

added to (and deleted from) any other groups. By default, the
guest user has no password, and a password can not be assigned.
This user can not be deleted.

19

Groups everyone
All users are automatically members of the everyone group. No

user can ever be removed from the everyone group unless the user
is entirely deleted. By default, this group has Read/Write access to
the public share. This can be changed, and access to other shares
can be granted or revoked. This group can never be deleted.

administrator
The administrator group always has Read/Write access to every

share. The admin user cannot be removed from this group, but
other users may be added or deleted. This group can never be
deleted.

Shares HDD1
HDD1 is the administrative root folder, provided so the adminis-

trator can backup all of the GigaDrive’s data by simply backing
up the contents of this folder. The administrator group always
has Read/Write access to this share. This share can’t be deleted.

public
By default, the everyone group has Read/Write access to the

public folder. The public folder’s access rights can be changed,
but it can’t be deleted.

Nested Shares

The Instant GigaDrive allows a folder inside a share to also be confi gured as
a share. This allows the nesting of shares to any depth, just like the folders
on your PCs hard drive. If you use this feature, you need to be aware of the
following points.

• In Windows’ Network Neighborhood, all shares are listed on the same level,
making the nesting completely invisible.

• Users cannot tell whether or not a sub-folder is in fact a nested share.

20

Nested Shares and Access Rights

Anyone with access to one share automatically has access to every share
beneath it. You can not provide access to an outer share while preventing
access to an inner share (fi gure 1). You can, however, deny access to an upper
share by granting a group’s access only to the shares beneath it (fi gure 2).
Because of this, shares access fl ows down, but does not fl ow up. Your most
sensitive data should therefore be stored in the outermost or upper share, not
in the innermost share.

Figure 1

Figure 2

Multiple Access Rights

While access to a share can be assigned to only one group, it is possible for
more than one group to access a share if nested shares are used.

For example, in fi gure 1, if access to the uppermost share is assigned to Group
1, and access to one of the folders beneath the uppermost share is assigned to
Group 2, Groups 1 and 2 will both have access to that second share as well

as all the shares beneath it.

Windows Client Setup

Introduction

This section will help you confi gure Windows so that you will be able to access
your network and the GigaDrive from your PC. The following items will be
checked or confi gured.

• TCP/IP protocol

• Access to the GigaDrive’s storage

• The GigaDrive’s printer

If your PC already has been confi gured for TCP/IP, you very well may already
be able to access the GigaDrive and its printer without changing any of your
Windows settings. Check your Network Neighborhood. If you don’t see it
anywhere in there, begin the Client Setup.

TCP/IP Setup already able to see the Instant GigaDrive out on the

1. Select the Control Panel - Network option in the Start Menu. You should

see the following screen.

Network Confi guration

2. If a line like the one highlighted (TCP/IP

-> Network card) is not listed, then you
need to install the TCP/IP protocol by
selecting Add - Protocol - Microsoft -
TCP/IP - OK.

Note: These screen-shots have
been taken from Windows 95,
and will be identical to screen
shots from Win 98. Windows NT

4.0, however, has a similar but
different TCP/IP setup function.
The process is intrinsically the
same, but some screens will
look different.

24

3. With the TCP/IP entry highlighted, click on the Properties button. The
IP Address tab will be selected. You should then see a screen like the

following.

IP Address

To act as a DHCP Client

Select Obtain an IP Address Automatically, as shown above. If you have
enabled the Instant GigaDrive to act as a DHCP Server, it will now provide IP
Addresses (and related data) to your PC when it boots.

To use “Specify an IP address” (fi xed IP Address)

• If your PC is already confi gured, no changes are required.

• If you just installed TCP/IP, you need to enter:

IP Address and Subnet mask (on the IP Address tab, as shown above)
Default Gateway Address (on the Gateway tab)

These values must be compatible with other devices on your LAN. Each PC
requires a unique IP Address (usually only the last fi eld is different on each

PC), and the same Subnet Mask.

The Gateway is the IP Address of your router or internet gateway. If you don’t

have a router or internet gateway, the address should be left at 0.0.0.0. If
you have a Router on your LAN, ask your LAN Administrator what values
to use.

Network Logon

To access the Instant GigaDrive, you must correctly logon to the network.

1. Check your Windows logon using Start - Settings - Control Panel -

Network. Ensure that the Primary Network Logon is set to Client for
Microsoft Networks, as shown below. If this is already set, there is no need

to make a change.

Checking Your Primary

Network Logon

25

2. After your PC boots, W indo ws will prompt you to logon to the network.
You must logon. If you press ESC, or click Cancel, network resources will

not be available. When you logon, you will need to use a valid User Name
and Password.

• If the Instant GigaDrive Administrator has defi ned users on the GigaDrive,
use the User Name and password supplied there.

• If you use a User Name and password which is not recognized by the
Instant GigaDrive, you can still use it with
guest access rights. By default, this allows
read/write access to the public share, and
allows you to use the printer.

Changing your Instant GigaDrive Password

Note: The admin pass­word can not be changed
using this method. The
Administrator Interface
must be used to change
the password for the user
“admin”.

Once the Instant GigaDrive Administrator has
given you a valid GigaDrive user name, you can
use the following procedure to change your password.

26

1. Start your WEB browser

2. In the Address box, enter: HTTP://ip_address/user.pl, where
ip_address is the IP Address of the Instant GigaDrive. If you do not know
the GigaDrive’s IP Address, ask the GigaDrive administrator.

3. You will be prompted for your name and password. Enter them.

4. On the next screen, type what you would like your new password to be.

5. Click Save, and then close your browser. Your password has been changed.

Password Management

You can confi gure your PC to work with only one password - the password
you use to log onto the network at startup. To do this requires that the User
Name and Password be the same on Windows, the Instant GigaDrive, and on
any other network server you may be accessing.

Changing your Windows password

• Your Windows password can be changed by using Control Panel - Pass-
words - Change Windows Password.

Changing the password on your other servers

• Only the Network Administrator can create and modify user names.

• To change your password, use Control Panel - Passwords - Change

Other Passwords. Select the Server, then
click Change. If Windows is unable to change

the password, it will display an error message.
Check with your Network Administrator for
the correct procedure.

Using the Instant GigaDrive’s Storage

To use the Instant GigaDrive’s storage, you must
map a drive letter to each GigaDrive folder you

wish to access. The drive will then be available to
all Windows programs.

1. Double-click the Network Neighborhood icon

on the desktop.

Note: When you try to
access a share or folder,
you may be prompted for
a password. If your Win­dows login name is the
same as your user name
on the Instant GigaDrive
but the passwords are
different, you can enter
your GigaDrive password
here. If your Windows
login name does not exist
on the GigaDrive, you will
only have guest access
rights. There is no pass­word which you can enter
in this window.

27

Network Browse

2. Locate the Instant GigaDrive, as shown above. If it is not listed, double­click Entire Network. Then double-click the Workgroup that the Giga-

Drive is in. (By default, the GigaDrive is in Workgroup.)

3. Double-click the Instant GigaDrive icon.

4. Right-click a GigaDrive folder (share) to which you have access, and select

Map Network Drive, as shown below.

Map Your Network

Drive

5. Select a drive letter for this folder, and check the Reconnect at Logon
checkbox. (If you don’t choose to reconnect, the mapping will be lost when
you shut down your PC.) Click OK.

6. This drive will now be available in Windows Explorer, and from the File-
Open or File-Save As dialog in all Windows applications.

Using the Instant GigaDrive’s Printer

Introduction

The EtherFast 10/100 Instant GigaDrive comes with a built-in printer server.
Confi guring your GigaDrive’s printer is easy, and by networking a printer
through your GigaDrive, you save space, money, and the hassles of dealing
with a stand-alone PrintServer. Any printer connected to the GigaDrive is
available to any network user, provided that user has access to the GigaDrive
itself. It will function exactly the same as any other network printer.

Using the Instant GigaDrive’s Printer

Complete the following steps to make the Instant GigaDrive’s printer available
from your PC.

1. Find out which printer is connected to the printer port on the GigaDrive.

2. Use Network Neighborhood to locate the GigaDrive, as explained in the
previous section.

3. Double-click the Instant GigaDrive icon. A printer icon should be appear.

4. Right-click the printer icon, and select Install. The Add Printer wizard
will begin.

5. Select the Manufacturer and Printer matching the printer connected to
the GigaDrive.

6. Follow the prompts to complete the installation.

7. The new printer will now appear in your Printer list, and can be used from
any Windows application.

8. Use the normal Windows commands to manage the printer:.

• Use Start - Settings - Printers to list all of your printers.

• Double-click the printer to view or delete the documents in the print

queue.

• Use File - Set as Default to make the selected printer the default printer.

• Use File - Properties to view or modify the properties of the selected

printer.

Troubleshooting

1. The GigaDrive Utility can’t • n• my Instant GigaDrive.

• Check that the Disk Server is properly installed, that the LAN connections
are OK, and that the GigaDrive is powered ON.

• If you are using a router, ensure that your PC and the Instant GigaDrive
are on the same network segment.

• Ensure that your PC has the TCP/IP network protocol loaded. This is done
by checking the Network option of the Control Panel. If an entry for
TCP/IP -> Network card is not listed, use Add - Protocol - Microsoft

- TCP/IP to add it.

2. The Instant GigaDrive is liste• in the GigaDrive Utility, but the A•min
button •oesn’t work.

• This will happen if the Instant GigaDrive’s IP Address is not compatible

with your PC. Use the Quick Setup button to assign a compatible IP
Address and Network Mask (Subnet Mask) to the GigaDrive. Click the
Refresh button to update the listing.

3. The GigaDrive is con• gure•, but I can’t • n• it in Network Neighbor­hoo•.

• Go to the Find function in the Start menu. Choose Computer, then enter

the GigaDrive’s name.

• If this doesn’t work, choose the Network option of the Control Panel to
check that a TCP/IP protocol is installed. If it isn’t installed, use Add -
Protocol - Microsoft - TCP/IP to install it.

• Check the network Bindings. First, ensure that the TCP/IP protocol is
bound to your Network card (NIC). Then, select your Network card in
the Control Panel, click Properties, and choose the Bindings tab. If
TCP/IP is not bound (checked), check it.

• Ensure that the TCP/IP -> Network card entry is bound to the Client for
Microsoft Networks service. Select the TCP/IP entry for your Network
Card, click Properties, and then choose the Bindings tab. If Client for
Microsoft Networks is not bound (checked), check it.

• If you don’t have a router, ensure that your IP Address is compatible with
the Instant GigaDrive’s. This means it needs to be in the same address
range (e.g. 192.168.0.3 to 192.168.0.254) and using the same Subnet
Mask (e.g. 255.255.255.0)

30

• If you do have a router, check that your Gateway IP Address is set
correctly. Ask your LAN administrator for the correct value.

4. When I click on the GigaDrive icon in Network Neighborhood, I’m
prompted for a password.

This can happen in the following situations:

• Your Windows Logon name is recognized by the GigaDrive, but your
Logon password is not. Simply enter your GigaDrive password, or make
your Windows password the same as the GigaDrive password.

• Your Windows Logon name is not recognized by the GigaDrive, default­ing you to guest access rights. Ask the GigaDrive Administrator to create
a user name for you. (Use the same name as your Logon name.)

• You do not have access permission for this share. Ask the GigaDrive
Administrator to grant you access.

5. When using the Web interface, some of the data will not • t on the
screen, and there is no scroll bar.

• You are likely using extra-large fonts in your Browser or in Windows.

To change your browser’s font size, select View from your web-browser’s
menu, and change the font size there. To change the size of your
Windows fonts, go to Display in the Control Panel. Choose Settings,

then click the Advanced button. Change the font size to either Small or
Large. Both should work.

6. A print job does not print and no error message is displayed.

• The amount of free disk space on the GigaDrive is probably not suffi cient
to spool (queue) the print job. The GigaDrive’s disk usage can be checked
using the Status - Disk screen on the GigaDrive’s Administrator interface.
If this is the problem, you must delete some print jobs.

1. Select Printer from the Status menu of the GigaDrive’s Administra-

tor interface.

2. Use the Delete Current Job option to delete the current print job, or
Delete All Jobs to delete all print jobs.
