NetGuardian 216 G4 Overview
1
Fig. 1.1 Compact, easy-to-install, right-size capacity - this device offers a low-cost way of effectively
monitoring smaller sites.
Effective, easy-to-install, light-capacity alarm monitoring
The NetGuardian 216 G4 is a compact, LAN-based, light-capacity remote telemetry unit. The NetGuardian 216 G4 is
designed for easy installation at small remote sites, making it cost-effective to deploy alarm monitoring throughout
your entire telecom network.
Powerful monitoring for smaller sites
The NetGuardian 216 G4 is based on the time-tested NetGuardian 832A design used in high-capacity models. This
telco-grade remote is housed in a durable aluminum case that can be rack or wall-mounted. This SNMP remote is
scaled to the needs of small sites, such as remote huts, collocation racks, and enclosed cabinets - perfect for any
site where a large capacity RTU would be more than you need.
·16 Discrete Alarm Inputs
·32 Ping Targets
·6 Analog Alarm Inputs
·2 Control Relay Outputs (Build option)
·1 Reach-through serial port (Build option)
·16/32 D-Wire temperature or humidity sensors (Build option)
Reach-through serial port gives LAN access to on-site equipment
The NG216 G4 also features a reach-through serial port. This port provides remote users with LAN-based Telnet
access to a variety of on-site telecom equipment, including switches, radios, PBXs and many other devices.
SNMP or T/Mon
The NetGuardian 216 G4 can report alarms to any SNMP manager or to the DPS Telecom T/Mon Remote Alarm
Monitoring System. The NetGuardian 216 G4 can also report via SNMP and DCPx concurrently to the T/Mon.
Easy Alerts via Email or SNMP
Email notification reports alarm events to the e-mail addresses of specified personnel and creates a supplemental
record of alarm events in addition to your master via SNMP traps.
Paging Notification Support
The optional paging functionality includes a 33.6K internal modem that provides full support for alphanumeric paging,
so you can automatically send detailed notifications and instructions to alphanumeric pagers, cell phones, and
PDAs.
Upgraded Web Browser
The overhauled web interface that boasts several time-saving new tools, including new analog gauges. You'll also

notice the impressive speed boost. Menus load very quickly, and the alarm status updates automatically without
requiring a page refresh.

Fig. 5.1 NetGuardian 216 G4 back panel connections
Power Connection5.1
The NetGuardian is powered by two barrier plug power connectors.
Fig. 5.4 Locking RIA power inputs
To connect the NetGuardian to a power supply:
1. Use the grounding lug to connect the unit to earth ground. The grounding lug is next to the symbol
.
2. Insert the eyelet of the earth ground cable between the two bolts on the grounding lug (Ground cable
not included).
3. Insert a battery ground into the power connector plug's right terminal and tighten the screw.
4. Insert a battery lead to the plug's left terminal and tighten its screw.
5. Insert fuse into the fuse distribution panel.
6. Check the power status LED for polarity.
7. 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 -36
VDC and -72 VDC.

11
Note: If the voltage does not read between -36 VDC and -72 VDC, stop immediately.
8. 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.
9. 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.

12
LAN Connection5.2
To connect the unit to LAN, insert a standard RJ45 Ethernet cable into the 10/100BaseT Ethernet port
on the back of the unit. If the LAN connection is OK, the LNK LED will light SOLID GREEN.
Serial Connection5.3
The NetGuardian 216 G4 has 3 build options for it's serial / dialup port. You can order your port as a
Yost RS-232, RS-485, 202 modem, or 4-wire 202 RJ45. The serial port is located on the back panel,
where it is labeled "Primary."

!Hot Tip!
If you are unsure of the serial port type on your NetGuardian, login to MyDPS and
click on the Product Information Search link. Type in the full part number of your unit
and click the Submit button to access the specifications.
The serial port can be used for two different functions:
·Reach-through proxy connection for LAN-based Telnet access to switches, radios, PBXs and
other equipment.
·Alarm reporting to the T/Mon Remote Alarm Monitoring System over an RS-232, 485, 202, or
dial-up modem.
Note: If the serial port is configured for alarm reporting to T/Mon, the port is not available for use as a
reach-through proxy port.

13
Telco Connection5.4
The NetGuardian 216 G4 features an RJ11 Telco port on the back of the unit. This port is used for dial-
up notification via your cell phone and alphanumeric pager.
