NOC CENTRAL EQUIPMENT (Related to the Department of Informatics and Telematics)

The Department of Informatics and Telematics building hosts the new NOC’s Computer Room

It is supported by the necessary air conditioning and a UPS of 120KVA, and a power generator for the case of power failure. The computing and network equipment are hosted on 4 racks of 19"APC NetShelter SX 42U 750mm wide

A) Network Equipment

The active network equipment of the building is Cisco and support the telecommunications and network needs. It includes:

  • 1 main switch having 48 ports and 12 simple PoE ports and a card with 7 optical ports with 1000Base-SX transceivers.
  • 1 Voice Gateway.
  • 1 call manager.
  • 2 optical switches for fast interconnections.
  • 4 switches (without PoE, × 48 ports) .
  • 2 switches for the IP telephony(with PoE, × 48 ports)
  • 40 IP phones
  • 6 wireless access points, indoor (access points), spreaded around the building.

The interconnection of the switches occurs via multimode optical fiber with Gigabit Ethernet (1GbE), while it is possible to support 10Gigabit Ethernet (10GbE) in the future. WAN connection provider is GRNET. The building is connected to the NOC located in the central campus of the Harokopio University (70, El. Venizelou) through a proprietary fiber optic network.


B) Mainframe equipment

The mainframe equipment supports the educational and research activities of the Department of Informatics and Telematics, and the Harokopio University overall. It includes:
