Introduction
Thank you for choosing the CPU
IP Access Switch Plus from LINDY.
This intelligent product delivers
straightforward setup, secure operation
and the ability to fully control one or
more computers from almost anywhere.
Remote control via a network
connection is nothing new and
software-only solutions to facilitate this
are commonplace. However, they all
present two major drawbacks: a) Special
software must be used on all of the
computers involved, especially the host,
and b) if that host ceases to operate, the
remote user is powerless to intervene.
The CPU IP is different and requires
only the remote system(s) to run a small
utility. The host system can run its usual
operating system completely unchanged
and needs only to be connected (via its
keyboard, video and mouse ports) to the
compact CPU IP box.
It is this external connection to the
CPU IP that keeps the remote user in
control. Even in the midst of a system
crash, the remote user can still view the
host’s condition as if sitting next to it.
Additionally, when the power switch
option is employed, a host system can be
remotely rebooted, no matter how badly
it has locked-up.
The CPU IP really starts to excel when
it is hooked to a suitable KVM switch.
Then its robust, secure and adaptable
operation is available across a multitude
of systems.
Note: Throughout this manual the LINDY
CPU IP Access Switch Plus is referred to
simply as the CPU IP.

Access Switch Plus
One host or many
On its own, the CPU IP provides remote access
to one host computer system. However, when
linked to a suitable KVM switch, the remote
user(s) can easily control a multitude of systems.
Optional power control
CPU IP provides the
opportunity to attach one
or more power switches.
These control the supply
to the host system(s) and
allow the remote user to
hard reset any system that
has suffered a failure.
IP network/Internet
The IP port allows direct
connection to an Ethernet-based
local network and from there
onto the wider Internet, as
required.
Alternatively, the robust CPU IP
security system will allow direct
connection to the outside world.
Local user
The console port allows
control of the system(s) by
a keyboard, video monitor
and mouse connected
directly to the CPU IP.
Modem/ISDN port
This port offers a
connection option that
can be used alongside,
or instead of, the IP
network link. It also
offers a backup route
should the network fail.
Four simultaneous remote users
CPU IP can support four remote users at any
one time. All of these may be connected via
the IP network port or one may be linked via
the modem/ISDN channel.

CPU IP Access Switch Plus features - front and rear
Considering its capabilities, the CPU IP is supplied within a remarkably compact
casing. Measuring just 198mm x 120mm x 43mm, it occupies just half of a
single (1U) rack space and provides most of its connectors at the rear face. The
smart front face features the IP network port and the operation indicators.

Power control port
Optionally use this port
to control one or more
power switches. These
allow the remote user to
take full control of the
host system(s).
KVM console
Connect a keyboard, video
monitor and a mouse to these
three connectors. These allow
you to perform the initial
conguration of the CPU IP.
Additionally, you can use these
to locally control the connected
computer(s).
Computer/KVM Switch
Link these connectors to the
keyboard, video and mouse ports of
the device to be remotely controlled,
either a single computer or a KVM
switch. The USB port on the right
is for future expansion and is not
currently used.
Modem port
Optionally use this port to
attach either a standard
modem or an ISDN adapter.
This feature provides an
alternative, direct-dial, remote
link into the CPU IP.

Host computer or KVM switch
The CPU IP can either connect directly to a single host computer or to range of
hosts via one or more KVM switches.
To connect a host computer or KVM switch
1 Ensure that power is disconnected from the CPU IP and the computer or
KVM switch to be connected.
(Note: If it is not possible to switch off devices prior to connection, then
a ‘Hot plug’ procedure is available – see the Hot plugging and mouse
restoration section for more details).
2 Connect the plugs at one end of a KVM cable set to the keyboard, video
and mouse sockets of the computer or KVM switch (for mouse plug
conversion information – see Appendix 7).

Local keyboard, video monitor and mouse
A locally connected keyboard, video monitor and mouse are required during the
initial conguration. These are also useful during normal use to allow quick local
control of any connected host computers.
To connect a local keyboard, video monitor and mouse
1 Position a suitable keyboard, video monitor and mouse in the vicinity of the
CPU IP such that their cables will easily reach.
2 Connect the keyboard, video monitor and mouse plugs to the sockets,
collectively labelled as ‘KVM CONSOLE’, at the rear of the CPU IP.

IP network port
The CPU IP provides an autosensing Ethernet IP port that can operate at 10 or
100Mbps, according to the network speed. The CPU IP is designed to reside
quite easily at any part of your network:
• It can be placed within the local network, behind any rewall/router
connections to the Internet, or
• It can be placed externally to the local network, on a separate sub-network
or with an open Internet connection.
Wherever in the network the CPU IP is situated, you will need to determine
certain conguration issues such as address allocation and/or rewall adjustment
to allow correct operation. Please refer to Networking issues within the
Conguration chapter for more details.
IMPORTANT: When the CPU IP is accessible from the public Internet or dial up
connection, you must ensure that sufcient security measures are employed.
To connect the IP network port
1 Depending upon where in the network the CPU IP is being connected, run a
category 5e or 6 cable from the appropriate hub or router to the CPU IP.
2 Connect the plug of the category 5e or 6 cable into the IP port on the front
panel of the CPU IP.

Modem/ISDN port
The CPU IP provides a serial port specically for you to connect either a modem
or ISDN terminal adapter. This can be used as a primary, secondary or backup
access port for remote systems, as best suits your overall conguration.
IMPORTANT: When the CPU IP is accessible from the public Internet or dial up
connection, you must ensure that sufcient security measures are employed.
To connect a modem or ISDN port
1 If possible, disconnect power from the CPU IP and the modem or ISDN
adapter.
2 Connect a suitable serial modem (non-crossover) cable to the serial port on
the modem/ISDN adapter.
3 Connect the other end of the serial cable to the port labelled COM1 at the
rear of the CPU IP.

Note: The default serial port speed is 115200K and a standard Hayes-compatible
auto-answer string is sent during startup. The default startup string is
‘ATZHS0=1’. Both the serial port speed and startup string settings can easily be
altered during the local or remote conguration - see Initial conguration for
more details. The other serial settings are xed at: No parity, 8 bit word and 1
stop bit.
Power supply connection
The CPU IP is supplied with a single power supply and an appropriate country-
specic IEC power lead. There is no on/off switch so operation begins as soon as
the power supply is connected.
To connect the power supply
1 Connect the low voltage output connector from the power supply unit to
the power socket on the rear panel of the CPU IP.
