Figure 3–21: ContentDirector and Network Switch Connections in Stretch Cluster
To connect ContentDirectors to network switches in a stretch cluster:
1. Starting with the ContentDirector at Site 1, connect a yellow fiber optic cable to NIC 3.
Connect the other end of the cable to an open port on the first network switch module at Site
2. This will be used for Private VLAN 1.
2. Connect a black fiber optic cable to NIC 2 on the ContentDirector at Site 1. Connect the
other end of the cable to an open port on the second network switch module at Site 1. This
will be used for Private VLAN 2.
3. Connect a white Ethernet cable to NIC 0 on the ContentDirector at Site 1. Connect the other
end of the cable to an open port on the first network switch module at Site 1. This will be
used for the Public VLAN.
4. Connect a blue Ethernet cable to NIC 1 on the ContentDirector at Site 1. Connect the other
end of the cable to an open port on the second network switch module at Site 1. This will also
be used for the Public VLAN.
5. For the ContentDirector at Site 2, connect a yellow fiber optic cable to NIC 3. Connect the
other end of the cable to an open port on the first network switch module at Site 2. This will
be used for Private VLAN 1.
6. Connect a black fiber optic cable to NIC 2 on the ContentDirector at Site 2. Connect the
other end of the cable to an open port on the second network switch module at Site 1. This
will be used for Private VLAN 2
7. Connect a white Ethernet cable to NIC 0 on the ContentDirector at Site 2. Connect the other
end of the cable to an open port on the first network switch module at Site 2. This will be
used for the Public VLAN.
8. Connect a blue Ethernet cable to NIC 1 on the ContentDirector at Site 2. Connect the other
