4.2. Set-up procedure

4.2.1. Preliminary procedure

Important

Before installation, check the integrity of the equipment by following the Delivery control procedure.

Note

To capture the flow of the network to be monitored, insert the GTap into the existing network.
This can be done either:

  • By replacing a multimode LC duplex optical jumper with two jumpers of the same type

  • By using the switch's mirroring ports, if so equipped

  • Apply the good practices for inserting a Tap on a network.
    If necessary, contact the Gatewatcher support or your usual Gatewatcher contact.

  • Procedure for installing the GTaps in a rack :

    • Insert the GTaps into the rack until you hear a click indicating that they are secured in the internal rails.

    • If the GTaps are difficult to insert into the rack, check that the internal rails are at the bottom of the rack and that the GTaps are aligned with the internal rails, with the front panel text vertically aligned.

    Note

    A 19-inch rack can hold up to six GTap_O_MM.

  • If necessary, mount the rack in a bay and secure it.

Note

The height of the GTap rack is 1U.

Important

Cleanliness of the optical fiber is essential for good signal transmission, as dust and other microscopic particles can disrupt or block the signal.
It is recommended to keep dust caps on unused connectors to reduce the risk of contamination.
In the event of a weak or absent signal, the first step is to clean the cables and connectors.
Before connecting them, it is recommended to clean optical jumpers and connectors using appropriate fiber optic cleaning equipment.

4.2.2. Procedure

  • Connection to the network to be monitored:

    • Connect the multimode LC duplex optical jumper of the network to be monitored to the `NET A` port.

    • Connect the multimode LC duplex optical jumper of the network to be monitored to the `NET B` port.

    Note

    For each jumper, remove the covers protecting the fibers and connect the jumper.

  • Connection to the sensing probe:

    • Connect the `TAP AB` port to the sensing probe using a split duplex jumper.

    • Connect the jumpers as shown in the diagram below:
