Question:

We have outsourced our server systems in an external data center! However, we want to monitor our server cabinets themselves. The racks are already densely packed and closet space is expensive. What size is the enclosure monitoring system of Didactum?

Answer:

The Rack Monitoring Systems of Didactum need one rack unit (1U).

The width of the appliance is 44, the height 4.4 and the depth of 7.5 inches.

19 inch mounting bracket for mounting the control unit in the technical or server rack are included.


Question:

What is the internal temperature sensor in Didactum IT monitoring system?

Answer:

Question:

I have seen that Didactum's IP capable monitors are equipped with a ground connection. What is this connection for?

Answer:

Put simply, the grounding / earthing terminal is used for the functional grounding of the networked remote measuring and monitoring devices in the context of electromagnetic compatibility (EMC).


Question:

Which cable should I use if I want to put the IP sensors farther away from main sensor unit?

Answer:

Most of our network enabled sensors are supplied with a 2 meter long RJ11/RJ12 connection cable as well as mounting material (mounting kit / screws). The sensors are connected to the IP-based monitoring system via Plug `n` Play and automatically identified.

If you want to install the Didactum analogue sensors farther away from the Didactum control unit, you can order suitable RJ11 / RJ12 extension cables as well as sensor cables in our online store. Important: Please note that the Didactum DC sensors are wired exclusively via 6-core 6P6C patch cable.


Question:

Which configurations / extensions are available on Didactum's Monitoring System 500 II?

Answer:

The infrastructure remote monitoring devices 500 II and 500 II DC (48V DC power supply) are supplied as standard including the extension board (Part No. 14120). As an option, the internal GSM modem (Part No. 14108) is available. Alternatively, you can also order the internal 1-Wire module (Part No. 14110). Please note that when ordering the 500 II (DC) Monitoring System including 1-Wire module, it is not possible to install the extension board (Part No. 14120). However, the 500 II (DC) monitoring device incl. 1-Wire module can be equipped with the GSM modem.

Here again in short form:

  • 500 II (DC) including extension board and GSM modem = possible
  • 500 II (DC) including extension board and 1 wire board = not possible
  • 500 II (DC) exclusive expansion board including 1 wire board and GSM modem = possible

Question:

What is the difference between the Didactum 50 and 100 III remote environmental monitoring unit?

Answer:

In simple words, the Didactum Monitoring System 100 III offers more functions. This monitoring device provides more connections for Didactum's intelligent IP capable sensors. The CAN expansion port (Controller Area Network) of 100 III monitoring device enables flexible expansion with additional sensor boxes or Dry Contact units. In addition a GPRS / GSM modem and a 19-inch Rack Mount Kit are also available for this monitoring device (at extra cost).


Question:

We received our SNMP based remote environmental monitoring devices and IP sensors from Didactum by air freight. On the leaflet we read that the 3V CR2032 lithium cells are not included. What is the reason?

Answer:

The carriage of lithium batteries has been identified as an emerging risk to airline operations. Therefore your web-enabled main monitoring unit is shipped by air freight without the 3V CR2032 lithium cell. Please buy this cheap battery cell on-site in your country. You find additional information here.


Question:

We use the Monitoring System 500 with built-in LTE modem option for the remote infrastructure monitoring of our data center. For critical events, different employees must be informed by SMS message about the incident. How many different phone numbers can be stored in the unit?

Answer:

In the web interface of the IP based monitoring unit, up to 15 different mobile telephone numbers can be stored in the "SMS Messages" entry. If SMS notifications have to be sent to more than 15 different phone numbers, please create a second alarm rule under the field "Logic schemes".


Question:

Our rack-monitoring-system (RMS) reports errors when sending SMS alerts. What is the possible cause here?

Answer:

Possible problems with SMS notification are stored in the log of your remote rack monitoring device. First, restart the unit (Web interface => "System Menu" => "Reboot the system" and click on "OK".) Alternatively, please remove the SIM card from the internal GSM / LTE modem and test it with your mobile phone / smartphone.

A faulty SMS dispatch can have the following causes:

  • Technical defect of the SIM card
  • SIM card is blocked (incorrect entry SIM PIN or blocking by the mobile service provider)
  • Negative balance on the account of the SIM card
  • Low signal level
  • Incorrect format of the telephone number
  •  Entering a wrong / invalid phone number

Question:

We are looking for a suitable solution for physically remote monitoring our distributed server rooms under Nagios. Does Didactum also offer a starter set?

Answer:

In the online shop for IT infrastructure monitoring solutions you find under Bundle a variety of starter sets. If you have questions or need a consultation, just contact our sales team.


Question:

Should my Monitoring System 100 with a built-in GSM modem be secured with a UPS?

Answer:

Didactum's LAN-based remote monitoring and alarm systems are equipped with capacitors, so that in the event of a power failure, alerts can still be sent theoretically via the integrated GSM or LTE modem. In practice, such an approach has risks. Basically, the use of an uninterruptible power supply (UPS) is recommended as protection against a power failure. Low cost standby or offline UPS systems are available from leading manufacturers.
