XSNet 2800 SW v.3
Part I: description, features, hardware installation
1. General description
XSNet 2800 SW switches will handle eight electrical
(Ethernet) data streams, and also provide two
independent gigabit optical uplinks through SFP single-
mode or multimode packages using two fibres per port
(wavelengths 850 nm, 1300 nm, or CWDM) or one
fibre (SM-BiDi option, ca. 10 km). The switches are
especially suitable for use in outdoor housings.
The non-blocking, highly configurable switches support
the following protocols: ARP, LLC, IP, UDP, IGMP,
Spanning Tree (STP) and Rapid Spanning Tree
(RSTP).
Front panel status LEDs provide information about
power, port speed and port activity.
The switches come in the form of double-width (14TE)
Eurocassettes fitting in MC 11 or similar power supply
cabinets, or as stand-alone units (/SA option). Device
configuration can be performed in-band using the built-
in http server. In-band device and link management
using a GUI can be performed with the aid of
Optelecom-NKF utility programs based on the MX
protocol. In an EB-2 type power supply cabinet, the
switches can be configured and managed with the SNM
protocol [variable by name protocol not implemented].
2. Front panel features

3. Installation
3.1. Initial configuration notes
Before installing and trying to link up the switch in a network, please read the separate guide detailing
how to set the IP address and subnet mask, and if necessary the gateway address, for initial installation.
3.2. Hardware installation
A Eurocassette module will slot into an Optelecom-NKF power supply cabinet, model MC 11 or similar. A
stand-alone model may be mounted in any suitable environment that will not make it overheat or malfunction in
other respects: some natural air circulation, moisture lockout and prevention of dust or grime accumulation are
always desirable.
The switch will power up in a few seconds, performing auto-negotiation on the 100 Mbit ports. The Spanning-
Tree Protocol (if applicable) and Rapid Spanning-Tree protocol have convergence times of 10-30 and typically 4
seconds, respectively. Generally, the ports will all be up and running within a minute after powering up into a
network.
3.3. Software installation
Only the items needed for putting the switch into operation, and some auxiliary features, will be described here.
With in-band configuration using the built-in HTML pages, the main switch parameters can be set. The
following chapters contain a description of how to go about this.

Part II: Configuration pages
1. Logging in
Logging in to the XSNet 2800 SW internal http server enables the user to configure the switch without using
separate application software. A standard Web browser will suffice to find the module by its IP address.
Activate the LOGIN button on the login screen that will appear (see figure 1 below).
After the Connect box appears (see below), a fresh module can be accessed as follows:
-login as ‘admin’
-leave the password field blank
-activate the OK button or press ‘Enter’
Figure 1. Part of the first screen: Login pane
Figure 2. Login box

After completing login, the Home page (see the Homepage section) will appear.
The other HTML pages can be then called up from the navigation menu appearing in the top left corner of each
page (figure 3a); each page may consist of several sections. Each section has an information button , which
can be activated to display help.
The HTML pages share the following features:
-a menu to access the pages (see figure 3a)
-a diagram (figure 3b) showing which ports are in use, i.e. connected to another active device
-panes (sections) showing parameter values, some of which are editable
-buttons, mainly SAVE, REFRESH and CANCEL, for sections with editable fields
Writing changes into the device after editing is done by activating the SAVE button.
The actual values still in the device are shown using the REFRESH button.
Activating CANCEL undoes any changes made before saving and shows the values as they were before editing.
Main operational variables and modes to be set are (see also figure 3a):
-Network addresses
-Port speed and mode
-Unicast and multicast
-RSTP (spanning tree/rapid spanning tree protocol) settings

2. XSNet 2800 Home page
This page (see figure 4) has the following sections:
-Identification pane: administrative data, including the article code, serial number, software version, and
uptime
-Labels pane: label entries (editable)
-Status pane: an alarm status overview (alarms active or not), including the level of the highest occurring
configured alarm (Module status field).
On this page, only the 32-character labels can be edited; please activate the SAVE button if after making changes
you wish to make them definitive and active. However, if you decide to stop editing and return to view the
original values, use either the REFRESH or the CANCEL button.
The Module status will be ‘OK’ if there is no configured alarm active (see the Alarms page); otherwise it could
appear as a character from A-N, depending on the alarms configuration.

3. XSNet 2800 network settings
For correct functioning of the 2800 SW, it is essential to set its network addressing to be compatible with the
subnet it is hooked into; see figure 5.
The Network settings pane shows the IP address. It is essential to set at least this address correctly and to
keep the value on record, otherwise management of the switch will require special software. Note that the
subnet address is also required.
The Subnet and Gateway settings show subnet mask and default gateway. Assuming the device IP address and
subnet mask are already set correctly, only the default gateway needs to be defined in order to connect the
network segment to others.
The entries in the MX alarm settings pane serve to support a video IP system using the MX protocol. The setting
shown (255.255.255.255) indicates the MX packets are being broadcast.
After filling in the addresses, use the SAVE button to set them. After saving, in-band communication with the
2800 SW will be interrupted and the user will have to contact the device again using the new IP address.

4. XSNet 2800 SW alarms
The Alarms settings page shows the Status and Alarm level settings panes. In the Status pane, the Module Status
entry shows the highest level of the occurring and configured alarms, while the other fields in that pane represent
the actual status of some alarms. These alarms are not necessarily assigned a level; this can be done in the pane
‘Alarm level settings’.
Alarm levels can be set to A-N, or to ‘_’ (equivalent to ‘O’), the latter meaning no alarm level set. In the
example screenshot, one alarm level was already set and another was in the process of being set. Setting an alarm
level A-N also means the alarm will actually go off if a certain condition is met. For the 2800 SW, these
conditions are:
Power supply alarm Indicates an active power supply alarm (2V5 or 3V3
outside 5% of their nominal value)
Temperature alarm Indicates an active temperature alarm (temperature above
the selected value, default is 70oC)
Link loss alarm (port 9) Indicates link of gigabit port 9 is down
Link loss alarm (port 10) Indicates link of gigabit port 10 is down
Bad connection alarm
(ports 9 & 10)
Indicates whether gigabit ports 9 and 10 together
experienced more than 10 000 CRC errors (value can be
changed using suitable software)
After setting an alarm level, first activate the SAVE button, then the REFRESH button to update other values
displayed.

5. 2800 SW VLANs
XSNet 2800 switches support up to 50 virtual tagged LANs, organizing ports into separate groups. These
VLANs are to be enabled from the VLAN Control menu with at least one entry in the VLAN Port Control menu,
and a management VLAN defined. The latter is essential: without it, all in-band contact with the switch would
be lost. So: define a management VLAN first before enabling VLANs.
The 802.1q tags can contain a VLAN ID and/or a priority level. If only the latter is present, the VID is zero; the
frame is then called a ‘P-frame’ (priority-only frame) not to be confused with a pause frame.
VLAN entries: defining a 2800 SW tagged VLAN
On the VLAN Entries page, use the edit window (see figure 7) to fill in a row for each VLAN you want to
define. For each port, two entries must be considered:
-the port VLAN membership, indicating that a port should be a member of the VLAN to be defined
(membership of more than one VLAN is of course allowed)
-untag (i.e. remove Q-tags), indicating that tags holding VLAN and priority information should be
removed from the output.
For a port connected to another switch, there should be no untagging if the VLAN extends over several
switches. For edge ports, the stream should generally be untagged.
A management computer should be connected to an untagging VLAN port unless the application running on it
and the network interface card involved will handle Q-tags sensibly.
By clicking on an existing VLAN entry, it can be edited in the edit window, indicated by the arrow. Pressing
SAVE will consolidate the modified entry if the VLAN ID did not change, or add an entry if a new VLAN ID
was added.
Pressing the DELETE button while an entry is present in the edit window will irrevocably disable and remove
that VLAN.
Remember to use the SAVE button to store your VLAN definitions and settings.
Before enabling VLANs on the VLAN control page, be certain to fill in matching VLAN IDs in the VLAN Port
Control pane there.
