FAQ - Building Network

If your network is not working, you can check the following points yourself:

1. Personal inverstigation

1. Is only one computer/connection affected? 
   1. Is the computer connected and the port created?
   2. Link?
   3.       Check configuration on the computer           
      • IP address and related values or driver
      • DNS
      • Domain
      • Speed + duplex setting
      • Ping to itself (localhost)
      • Ping to own network
      • Ping to external world

2. Visual cabel inspection(espacially optical fibers)

1. kinked?
2. bending radii observed?
3. plug clean?
4. fibers reversed?

3. Network components between computer and data outlet?

1. Switch
   • Power available?
   • Uplink active?
   • Link of computer active?
2. Media converter
   • Power available?
   • Link and activity available (both ports)?
   • TP port straight/crossed?
   • Check cable (is it properly plugged into the port, ...)
3. Transceiver
   • Link available
   • Check cable (is it properly plugged into the port, ...)

You can carry out the following points yourself:

Visual inspection

• Cable
• Link at the media converter 
• Link at the switch/router 
• own switch:
  • View/edit the configuration (if manageable)
  • replug
  • reset
• Switch/router managed by the IT Center
  • Link?
    -> If not, call IT Center
• Own connection (cable) and components
  • Cable measurements
  • Exchange
• Connections managed by the IT Center (cable) and components
  • E-mail / call IT Center

If your network is running slowly, you can check the following points on your own:

Computer

• Check speed adjustment
• Check duplex setting
• Check driver
• Collisions?
• Check/exchange cable 
• Check/exchange network component
• Current load on the network

The IT Center can help you with the followig points:

• Exchange of components
• Replacement
• Configuration of network components (switches, routers...)
• cable measurements
  • Damping
  • Length of connection (limit values exceeded?)
  • Ping ability into the network

If you have problems with uplink and network components, the IT Center can help you as follows:

• Inspection by our staff
• cable test and exchange
• central network components + configuration
• counseling on network structure to prevent future problems
