3. Installation
The Cirrus2 should be installed on a flat, level bench top with adequate ventilation as specified in Specifications section
of this manual. Periodic maintenance will be required during the lifetime of the unit, with this in mind some thought should
be given to the location.
All connections should be easily accessible, with the Cirrus2 positioned so that strain is not placed on any of the cables
or connectors.
Connecting to the Ethernet Port
Overview
Before connecting a cat5 patch lead to the socket marked “ETHERNET” please take the time to read through the
following sections.
If the Cirrus2 is to be installed on your company network, then there are a number of different network configurations that
must be considered before you continue.
There are four main network technologies employed in the distribution of network addresses (IP addresses) to network
devices, the Cirrus2 can be configured to use any of the following:
Auto-IP
A mechanism where in the absence of a DHCP or BOOTP server on the network, network entities can obtain their
unique IP addresses by a process of arbitration between devices. If a DHCP or BOOTP server is present on the network,
Auto-IP will obtain an IP address from the server.
DHCP
Short for Dynamic Host Configuration Protocol, a server running on the network is responsible for assigning dynamic IP
addresses to devices on a network.
BOOTP
Short for Bootstrap Protocol, an Internet protocol that enables a diskless workstation to discover its own IP address and
the IP address of a BOOTP server on the network.
Static
Each address is issued manually to each device by the network administrator.
By default the Cirrus2 is configured for Auto-IP which is by far the simplest method if you are new to networking, or are
installing the Cirrus2 into an existing Auto-IP or DHCP network.
If you intend to connect a Cirrus2 to an existing network, then you must consult your IT Specialist for advice on how the
network assigns IP addresses.
