PRODUCT DESCRIPTION
1. Product Description
The MP3 chassis is a 3RU design that comes in both a passive and active conguration. Both congurations include options
for dual cable management bars and a large cable management tray as well as user congurable horizontal and vertical
cable management systems. The MP3 active chassis also include a ber management tray that can be congured into two
positions.
The passive and active chassis’ can accommodate up to 24 single-width passive modules (DC Logic A/B RF Switch; 2,
4, 8, dual 4-way and triple 2-way splitters\combiners; DC & triple DCs) or up to 12 dual-width modules (16-way splitter\
combiners).
The active chassis can accommodate all the modules that a passive chassis can, but also up to 12 dual-width active modules
(amplier, power supply, optical receiver\transmitter, RF Switch).
The active chassis comes with a +24 VDC power interface backplane/rail and a removable communications module that
draws power from the rail. This communications module can be removed without affecting the operation of the modules in the
chassis by removing the two Phillips screws on either side that fasten it to the chassis. All active modules are hot-swappable.
Power is supplied to the backplane by installing an MPAC or MPDC power supply into one of the chassis slots or by remotely
powering the chassis from an external 24 VDC supply. The MP3 active chassis is equipped with an HMS compliant SNMP
management system. An RJ-45 port is used for both set-up and status monitoring. No custom software is required.
Please refer to the web page for up-to-date specications – www.atxnetworks.com
__________________________________________________
1Provided that the chassis is not being solely powered via the terminal block on the comm module, there would simply be no alarms and no remote
adjustment of parameters. The modules would continue to run with the last set values.
2It is not recommended to hot swap a power supply module into a full chassis if there is no other power supply present. The current surge to supply a
full rack of active modules would be stressful on the electrical contacts during mating and may reduce the lifespan of the chassis and power supply. It
is recommended that you install the power supply rst, then apply AC or DC input to the power supply connector.

INSTALLATION
2. Installation
The MP3 is a 3RU chassis and comes pre-assembled and ready to mount to any existing 19” rack cabinet hub system using
10/32” rack screws.
NOTE: This equipment is intended for installation in a RESTRICTED ACCESS LOCATION only.
NOTE: Not for use in a computer room as dened in the Standard for Protection of Electronic Computer/Data Processing
Equipment, ANSI/NFPA 75.
Rack Mounting Precautions
a) Elevated Operating Ambient - If installed in a closed or multi-unit rack assembly, the operating ambient temperature
of the rack environment may be greater than room ambient. Therefore, consideration should be given to installing
the equipment in an environment compatible with the maximum ambient temperature (35ºC) specied by the
manufacturer.
b) Reduced Air Flow - Installation of the equipment in a rack should be such that the amount of airow required for
safe operation of the equipment is not compromised.
c) Mechanical Loading - Mounting of the equipment in the rack should be such that a hazardous condition is not
achieved due to uneven mechanical loading.
d) Circuit Overloading - Consideration should be given to the connection of the equipment to the supply circuit
and the effect that overloading of the circuits might have on overcurrent protection and supply wiring. Appropriate
consideration of equipment nameplate ratings should be used when addressing this concern.
e) Reliable Earthing - Reliable earthing of rack-mounted equipment should be maintained. Particular attention should
be given to supply connections other than direct connections to the branch circuit (e.g. use of power strips).”
2.1. Module Installation Into the MP3 Chassis
All MAXNET II active and passive chassis have 24 grooves that act as guide slots for the active and passive modules.
Passive modules and the DC Logic Switch can be inserted into any of the 24 slots. Active modules must be inserted into the
odd number slots indicated by the white markers on the bottom rail of the chassis. These odd numbered slots are the
only slots that will allow an active module to be connected to the active chassis backplane to receive power and allow monitor
and control of the module. To insert a module, align the module guide rails to the chassis guide slots and then gently slide
the module into a locked position (the module should be ush against the top and bottom rail of the chassis). No mounting
hardware is required. To remove a module, grab the front handle on the module and gently lift and pull back the module until
it is clear of the chassis guide rails.
NOTE: When installing the MPAC or MPDC Power Supply, the GND bonding terminal #1 on the back of the MPAC or
MPDC Power Supply shall be connected to the chassis ground lug.
2.2. Powering the Active MP3 Chassis
The MP3 active chassis can be powered by power supply modules (MPAC-110, MPAC-220 or MPDC) installed in one of the
slots of the chassis, or by connecting power directly to one or both of the terminal block inputs on the rear of the chassis. Both
connections are not necessary unless redundancy is required. If the source of 24 VDC is not an MPXX power supply, the line
should be fused at a minimum with a 10 Amp slo-blo fuse. A disconnect device is required between the 24 VDC supply and
the Chassis remote power terminals.

HARDWARE NETWORK SET-UP
3. Hardware Network Set-up
The MP3 active chassis can be easily connected to an existing network through the use of a patch cable connected between
the network port on the rear of the chassis and any switch or router. For a connection directly to a PC or laptop, use a
crossover cable. This product has been veried to work on Windows XP/2000 and Linux operating systems.
3.1. LED Indicators
There are four LED’s visible at the rear of the chassis. Two small square LEDs on the RJ45 port itself (see the next section
for details on these), a large yellow ‘COM’ and green ‘24V’ LED.
The ‘24V’ LED indicates the presence of power to the chassis and comm module, it should always be solid and bright.
The ‘COM’ LED will be solid during the boot cycle of the device but should start blinking after approximately 2 minutes. It must
always be blinking during regular operation to indicate the monitoring software is running.
3.2. Ethernet Port
The RJ45 Ethernet port visible at the rear of the chassis is actually the DC-ME-01T-C embedded device server, manufactured
by Digi International and loaded with custom ATX rmware. The following gures and text were taken directly from the
“Digi Connect ME & Digi Connect Wi-ME Hardware Reference”. For more information, please go to www.digi.com.
The Ethernet connector is an 8-wire RJ-45 jack that meets the ISO 8877 requirements for 10/100BASE-T. See the following
gure and table for pin orientation and pin assignments.
The yellow LED indicates whether a valid network connection is present. It should be solid. Otherwise, check the network
cable or the piece of hardware that has been connected to the network cable (switch, router or PC’s network card).
The green LED indicates network activity. It will be solid during any boot process (approx 2 min) and then blink if there is any
network trafc. If it remains solid, this may be indicative of corrupt hardware – contact ATX Networks.

STATUS MONITORING
4. Status Monitoring
4.1. Chassis Interface Options
The Active MAXNET II product line can be monitored and controlled in either of two ways:
a) A free, web-based interface. This comes pre-installed on every chassis and provides a user friendly method of
conguring the administrative set-up and all monitoring and control. It is based on SNMP, but requires little knowledge
of SNMP. Any Internet browser, such as Internet Explorer, is all the software that is required.
b) Any third-party SNMP Management software (eg. www.castlerock.com, www.ndt-inc.com/SNMP/MIBrowser.html )
may be purchased separately. These suites tend to be expensive and not as user friendly as the web interface. The
web interface is also still required for administrative set-up. The 3rd party interface is recommended only for systems
that have an existing SNMP architecture. All MIBs (Management Information Bases) are freely downloadable from
the SCTE (www.scte.org/standards). ATX was able to support all modules using the SCTE standard HMS MIBs, so
no custom MIBs are required.
4.2. Software Network Set-up
a) Recommended: Connect the chassis to a PC/laptop directly with a cross-over network cable.
Alternative: Connect the chassis to a switch or router using a patch network cable.
b) Enter the IP address of the chassis as the URL in a web browser. By default (factory reset), this will be 192.168.0.1.
If the device does not respond, see Troubleshooting section at the end of this document.
c) The login page should appear. Login as administrator (default password for all levels is the lower case name of the
level, i.e. Observer password is observer).
d) The conguration settings page should appear. It is important to either use DHCP or (preferably) assign a unique
IP address to each MP3 chassis that will be on the same subnet as your DHCP server assigns addresses. “Same
Subnet” refers to an IP address that has the same rst three octets, but a unique fourth octet e.g. 192.168.0.1 and
192.168.0.2 are on the same subnet.
e) Obtain a list of IP addresses from your IT department to use for your chassis’ and assign them one by one. If DHCP
is chosen, then this is not required, but you may have trouble nding out what IP address the DHCP server assigned
to each chassis, and it may change during a reboot of the chassis or DHCP server, so it is not recommended unless
the DHCP server is set to assign static IP addresses to the unique MAC addresses of each chassis installed.
f) There are several other options that can be set at this time, see Table 6 for a list.
g) Select ‘save changes’ and reboot. The device will take approximately 90 seconds before it is responsive again.
Remember that your PC/laptop must be set to the same subnet to ‘see’ it, so if you just assigned an IP address
other than 192.168.0.x, then you will need to change your PC’s IP again. It is recommended you change all chassis
IP addresses before reverting your PC back to DHCP.
4.3. Web Interface
The MAXNET II chassis uses an integrated web page to supplement the SNMP management. All conguration of the chassis
(static IP address, trap/email recipients, rmware upgrades, etc) must be done through the web page. Simply use any web
browser (Internet Explorer, Firefox, etc) and enter the IP address of the chassis as the URL. Login as administrator to modify
conguration and have full read/write access to monitor and control modules. Login as Operator to have full read/write access
or login as observer to have read-only access. There is only one password per login level.

CHAPTER 4: STATUS MONITORING
4-2 MAXNET®II – MP3 Active / Passive Chassis – Installation & Operation Manual
4.4. Module Replacement
In order to facilitate the replacement of any MAXNET II module, the software set-up information of the module such as HI
and LO alarm thresholds and alias are stored in the chassis itself and not the module. If any module is removed the chassis
and the same module or another of the same type is inserted into that slot of the chassis, then this conguration data will be
maintained.
This is not true for switch parameters though. In order to meet switch time specications at the module, this information
is stored within the module itself and therefore will travel with it wherever it is installed next. These parameters include
hysteresis, switch threshold, wait to restore time, etc.
4.5. Factory Reset
A factory reset will restore the chassis to the state which it left the ATX production facility.
4.5.1. Parameters That Will be Changed
IP address = 192.168.0.1
NetMask = 255.255.255.0
Gateway = 192.168.0.254
Passwords set to same text (but all lower case) as the login level. e.g. Operator password is operator.
All analogue and discrete alarm thresholds of modules will be reset to default values (except RF and optical switch data as
mentioned in the Module Replacement section above).
Alarm log will be cleared.
4.5.2. Purpose
Common reasons for requiring a factory reset are:
a) The chassis is unresponsive, or the IP address is not known
b) The Administrator password has been forgotten
c) The yellow COMM LED does not blink after the 2 minute boot cycle, even after a power cycle or press of the RESET
button
4.5.3. Method
If you are sure you want to factory reset, hold down the RESET button near the RJ45 port for at least 10 seconds. The yellow
COMM LED will be solid-on during this time, and once it turns off you can release the button and the reboot process will
begin.
