Resilience 4-35
CAUTION: Remember that you must always follow
the hub connection requirements when linking hubs
together, which involves the use of port 8 and the
MDI/MDIX switch.
If port 8 is already in use, you may need to use special
crossover cabling for any further links you wish to
make. Crossover cables allow you to make a
connection between two MDIX ports. Contact your
supplier for information on doing this.
To set up a resilient link pair:
1
Disconnect the hub which is to provide the standby
port from the network. We recommend you do this,
even though it is possible to set up links while still
connected, to avoid loops being formed accidently.
2 Do one of the following:
■
Double-click on the graphical representation of
the hub (but not on a port).
■
From the Configure menu, select General Info ...
3 In the General Info dialog box, choose the
Resilience
category.
The Resilience Links panel is displayed.
4
In the Resilience Links panel, click on Create .
Quick Config Manager displays the Create Resilient
Pair dialog box, as shown in Figure 4-16 .
5 In the Create Resilient Pair dialog box, choose the
port for the main link, followed by the port for the
standby link.
6 Click on OK .
7 Reconnect the hub with the standby port on it to the
network.
When you have created a resilient link pair, it is
added to the table and is color-coded as follows:
■
Green — Both Main link and Standby link are OK.
■
Yellow
— One of the links is OK, the other has
failed.
■
Red — Both Main link and Standby link have
failed.
