SAFETY
1.0 Installation.
Unless otherwise stated TSL equipment may be installed at any angle or position within an operating
temperature range of 5°~ 30°C .
The RJ45 connector is for use only with an Ethernet 10/100 system.
All TSL equipment conforms to the EC Low Voltage Directive:
EC Low Voltage Directive (73/23/EEC)(OJ L76 26.3.73)(LVD).
Amendment: (93/68/EEC) (OJ L220 30.8.93).
CAUTION:
Always disconnect equipment connected to a powered MDU before performing any maintenance.
Potentially hazardous voltages are present even after the operation or removal of a fuse, unless the front
panel circuit breaker is set to OFF.
Earthing/Grounding
In all cases, the frame of the equipment must be earthed on installation. Connection to an earthed strip
running the length of the frame is ideal.
The earth pin on the mains inlet connector is connected to the metal frame of the equipment, to 0 volts on the
internal DC PSU and to signal ground, unless otherwise stated. All metal panels are bonded together. Rack
mounted equipment must be earthed (grounded).
Mounting
Careful consideration of the equipment location and mounting in racks must be made. In particular,
consideration must be given to the stability of free-standing racks by mounting heavy equipment low in the
rack. The rear of the unit should be supported in the rack.
Power
This equipment is designed for installation in any position in a rack.
Consideration must be given to the supply circuit loading and switch on/fault surges that will affect overcurrent
protection trips and switches etc.
Check that the fuse rating is correct for the local power (mains) supply. Replacement fuses must be of the
same rating and type for continued protection against fire risk.
The equipment rating is shown on the rear panel.
No power supply cord is provided with this equipment but the inlet connector is.
Do not switch on until all connections are made.
Ventilation
Due consideration for cooling requirements must be given when mounting the equipment. The equipment
contains an internal temperature sensor.
General
If equipment is installed in a closed unit, consideration must be given to providing forced air cooling in order
that the maximum recommended temperature is not exceeded.

MDU12-PMi Manual 6 Issue 4
WARRANTY, MAINTENANCE AND REPAIR
All TSL equipment is guaranteed for one year from the date of delivery to the customer’s premises. If the
equipment is to be stored for a significant period, please contact TSL concerning a possible extended
warranty period.
Failure during warranty
If any TSL product should fail or become faulty within the warranty period, first please check the PSU fuses.
All maintenance work must be carried out by trained and competent personnel.
If equipment has to be returned to TSL for repair or re-alignment, please observe the following overleaf:

3.0 Introduction
The unit presents three control interfaces; web interface (http), SNMP interface, and the serial port on the rear
of the unit.
The default IP address from the factory is 192.168.100.235, with a subnet mask of 255.255.255.0. The serial
port interface can be used to set a new IP configuration and also to set a user name and password (needed to
access the web pages). The power must be cycled after this operation for changes to take effect.
Refer to section 5 p15 for initial configuration settings.
4.0 Operation
Upon connecting the unit to power it will go through a quick boot up procedure with normally the LEDs going
from Red to Amber to Green.
The following login screen will be seen. The unit is now on-line.
The default IP address is 192.168.100.235
The Username is <<root>>
The Password is <<telsys>>

4.4 The SNMP Screen
4.4.1 SNMP Alarms
The unit generates SNMP Trap Alarms to the IP address(es) configured in the SNMP setup page when the
following events occur:
1) A GPI input changes state.
2) A fuse fails or is replaced with a good fuse.
3) The internal unit temperature exceeds/drops below the threshold set in the SNMP web page.
4) An output goes Over Current or Under Current as set from the Output page.
5) The input voltage breaks the upper or lower threshold values as set on the system page.
For details of these and other SNMP features, see the supplied SNMP MIB file.
Press << Update >> when done.
NB Allow the page to refresh before cycling the power to check the settings.
4.4.2 Email Alerts
For each of the alarms as detailed above, the unit can send an email alert as well.
Check the box “Enable Email alerts on alarm event:”
Then put in the IP address of the email server, and the email address to where the alert should
be sent.
Your IT manager will be able to help in setting this up.
Press << Update >> when done.
NB Allow the page to refresh before cycling the power to check the settings.

MDU12-PMi Manual 17 Issue 4
5.0 Initial Configuration
Consult your System Administrator for appropriate IP and subnet mask settings.
•Connect a terminal running at 9600, N, 8, 1, Flow control-None; to the serial port.
(HyperTerminal for example).
•Power the unit.
The following ident string will display:
MDU12-PM FVX.XX
After a short delay the unit will then report:-
Ready
To program the parameters:
•Press <<Escape>> and wait for the prompt:
IPAddr?
•Enter the desired IP address, e.g. 192.168.0.1
•Then wait for the next prompt:
Subnet?
•Enter the appropriate mask e.g. 255.255.255.0
•Then wait for the next prompt:
User?
•Enter a username (max 12 characters). Factory default is <<root>>
•Then wait for the next prompt:
Pass?
•Enter a password (max 12 characters). Factory default is <<telsys>>
When these settings have been saved, the prompt <<Updated>> will appear.
•For the new IP settings to take effect, cycle the power on the unit.
Checking units for IP address via serial port.
If you need to check an MDU’s address then once the ready prompt has appeared type “?” and the current
settings for IP Address; Subnet Mask; Gateway; & Mac Address will be shown on the screen.
Web interface (http)
Using any browser (e.g. Microsoft Internet Explorer) you can browse to the IP address previously set. Use
the username and password you have previously set to access the configuration pages.

Typical external wiring for Circuit 1.
This shows the +5V supply as switched.
The circuit is not polarity conscious. The maximum input voltage without additional current limiting resistors is
+12V The internal resistors are 4K7 per circuit. Either the 0v or the +5V may be switched.
The Ethernet connector
A 1:1 cable should be used to connect to a hub as is normal practise.
7.0 Response Times
Remote Monitoring
The full unit status of the unit is sampled every 200mS. Any further delay is due to the SNMP agent compiling
the trap and then sending it on the network interface.
Typically, agents give priority to analysing network traffic and then look at the trap queue when idle.
Start up delays
Maximum delay is 256 seconds between each relay in Sequential Start mode and up to 50 seconds delay per
output in Delay Start mode.
8.0 Temperature Indications
The temperature reading is designed to assist in knowing the overall temperature in the rack, as the MDU is
at the top of it.
The maximum recommended figure is 65° C.
Going over or under the preset threshold generates an SNMP trap alarm, as detailed in the MIB.
