TempDefender G2 Overview
1
The TempDefender G2
Could you estimate how much money your company has invested in your IT server room or data
center? How much is your network uptime worth to you? These questions might be difficult to answer,
but monitoring your valuable IT equipment certainly doesn’t have to be.
You need a compact, simple, and reliable device to monitor basic environmental conditions (like
temperature, humidity, smoke...) around your valuable equipment. Without this basic visibility, it’s just a
matter of time before your investment in your server room is seriously damaged.
·8 Discrete Alarm Inputs
·1 to 4 D-Wire sensor input jacks (Build option), supporting up to 32 sensors (sold separately)
·3 Control RelayOutputs (Build option)
·Fast, integrated web browser
·32 ping targets to monitor other devices on the network
Meet the TempDefender G2
This small device keeps tabs on all the environmental levels that affect your servers, phone closets,
data centers, and other equipment locations. The 8 discrete alarms on the back panel are used to
monitor dry contacts, such as motion sensors, UPS, smoke detectors, flood sensors, AC and room
entry.
What’s the current room temperature? When was the last time someone entered the room? Get all of
this information - right from your networkPC.
Don’t wait until the day your AC unit fails and your server closet overheats to start protecting your
gear. This small, 1RU device alerts you of changing conditions 24 hours a day, 7 days a week, either to
your cell or SNMP manager. The TempDefender G2 is the cost-effective way to stay proactive in your
monitoring.

Common Applications for the TempDefender G2
The TempDefender G2 reports alarms as SNMP traps over LAN and supports DCP polling over RS-232, RS-485 or
LAN. The TempDefender G2 supports simultaneous SNMP and DCP operation.
The TempDefender G2 supports both LAN and serial port connectivity. The LAN connection and serial port can be
used at the same time to support simultaneous SNMP and DCP alarm reporting. However, only one DCP channel
can be used, therefore the TempDefender G2 cannot simultaneously report DCP over LAN and DCP over serial port
connection.
In addition to its 8 discrete input points, the TempDefender G2 has 3 control relays, all form A, user defined NO/NC
with short, 8 analogs, and dwire. The control relays allow network administrators to respond remotely to threats to
system integrity. Using the control relays, network administrators can turn on backup generators, open doors and
gates for emergency access, reboot equipment, or perform other functions. The TempDefender G2 also allows you to
reverse the logic state of the alarm on a point by point basis for discrete alarms.
Another feature of the TempDefender G2 is user-defined alarm qualification times. This will allow you to clearly
distinguish momentary status changes from serious problems.

* This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15 of the FCC Rules. These limits are
designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment
generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful
interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference in which case the user will
be required to correct the interference at his own expense.

Tools Needed4.1
To install the TempDefender G2, you'll need the following tools:
Phillips No. 2 Screwdriver Small Standard No. 2 Screwdriver
PC with terminal emulator,
such as HyperTerminal
Mounting4.2
The TempDefender G2 can be flush or rear-mounted
The TempDefender G2 mounts in a 19" rack or a 23" rack using the provided rack ears for each size. Two rack ear
locations are provided. Attach the appropriate rack ears in the flush-mount or rear-mount locations shown in
Figure 6.2.1.
Note: Rack ears can be rotated 90° for wall mounting or 180º for other mounting options (not shown).

7
Power Connection4.3
The TempDefender G2 uses single or dual (Optional) power inputs, powered through two barrier plug power
connectors.
TempDefender G2 Power Terminals and Fuses
To connect the TempDefender G2 to a power supply:
1. Locate the metal grounding lug next to the symbol . Use the grounding lug to connect the unit to earth
ground.
2. Insert the eyelet of the earth ground cable between the two nuts on the grounding lug (Ground cable not included).
3. Choose a barrier plug power connector to attach your power cable to. One plug is used for main power and the
other is used for backup power. Both plugs are interchangeable so it does not matter which plug you select. Each
plug's right terminal is Ground and its left terminal is Battery Lead.
4. Insert a battery ground into the power connector plug's right terminal (GND) and tighten the screw.
5. Insert a battery lead to the plug's left terminal and tighten its screw.
6. Insert fuse into the fuse distribution panel.
7. Check the power status LED for polarity.
8. Measure voltage. Connect the black cable onto the ground connector of your Digital Voltage Meter (DVM) and red
cable onto the other connector of your DVM. The voltmeter should read between the values listed on the silk
screen next to the power connector.
9. Insert the local fuse into the power fuse slot. The power plug can be inserted into the power connector only one
way to ensure the correct polarity.
Note: The negative voltage terminal is on the left and the GND terminal is on the right.
10.Verify that the LED is lit. To confirm that power is correctly connected, the front panel status LED will flash
RED and GREEN, indicating that the firmware is booting up.

Integrated 10/100BaseT Ethernet Switch (Optional)5.1
TempDefender G2 with integrated 10/100Base T Ethernet switch
You can order your TempDefender G2 with an optional integrated Ethernet switch, which provides seven regular
Ethernet ports. The integrated switch is powered by the same power as the TempDefender, which provides more
secure, more robust operation than switches that run off commercial power. The integrated switch also frees valuable
rack space be eliminating an unnecessary extra unit.
Regular Ethernet port pinout
The seven Ethernet ports of the switch are regular straight-through Ethernet ports. The pinout for the regular Ethernet
ports is shown in the figure above.

Quick Start: How to Connect to the Temp Defender G2
8
Most TempDefender G2 users find it easiest to give the unit an IP address, subnet and gateway through the front
craft port (TTY interface) to start. Once these settings are saved and you reboot the unit, you can access it over LAN
to do the rest of your databasing via the Web Browser interface.
Alternative option: You can skip the TTY interface by using a LAN crossover cable directly from your PC to the
TempDefender G2 and access its Web Browser.

...via Craft Port (using TTY Interface)8.1
TempDefender G2 Craft Port
Use the front panel craft port to connect the TempDefender G2 IT to a PC for onsite unit configuration. To
use the craft port, connect the included DB9 download cable from your PC's COM port to the craft port.
Note: The following images display the setup process done in Windows XP.
The following steps will occur the first time any DPS USB equipment is used on this PC. If you've used a
different DPS USB device before and have installed the DPS USB drivers, then skip to Step 9.
When you first connect the TempDefender G2 to your PC via USB, a "Found New Hardware" message will
appear:
1. Click the "Found New Hardware" message/icon to launch the "Found New Hardware Wizard".
2. Select "Install from a list or specific location (Advanced)"
3. Click "Next >"

13
4. Select "Search for the best driver in these locations."
5. Insert TempDefender G2 Resource Disc (CD) into your PC.
6. Click "Browse"
7. Select the "Driver" folder of your TempDefender G2 Resource Disc Disc (CD) and click "OK"
The following message will confirm installation of a new "USB Communications Port"

14
8. Click "Finish" to close the Wizard.
Now that the driver has been installed, a new COM port is being emulated on your PC. Before using
hyperterminal, you must confirm the identity of that new COM port (COM1, COM2, COM3...) in the Windows
Device Manager.
9. Right-click the "My Computer" icon on your desktop, then click "Manage"
