3.
Remove the transceiver. (SFP transceiver shown).
4.
Install dust plugs on the fiber-optic transceiver and rubber plugs on the fiber-optic cable.
CAUTION:
Be sure to install the dust plugs on the fiber-optic transceiver and the rubber plugs
on the fiber-optic cable. The plugs and caps protect the transceiver ports and cables from
contamination and ambient light.
Recommended stacking connections
Stacking links are used to interconnect Virtual Connect Ethernet modules when more than two Virtual
Connect Ethernet modules are installed in a single enclosure. This feature enables all Ethernet network
controllers on all servers in the Virtual Connect domain to have access to any Virtual Connect Ethernet
module uplink port. By using these module-to-module links, a single pair of uplinks can function as the
data center network connections for the entire Virtual Connect domain. Stacking enables any server NIC
physically connected to a VC module to be connected to any Ethernet network.
Each interconnect module has several numbered Ethernet connectors. All of these connectors can be used
to connect to data center switches or they can be used to stack Virtual Connect modules and enclosures.
Virtual Connect automatically detects when one Virtual Connect Ethernet module port is connected to
another Virtual Connect Ethernet module port within the domain and turns the port ID indicator amber.
All Virtual Connect Ethernet modules within the Virtual Connect Domain must be interconnected. Any
combination of 1-Gb and 10-Gb cables can be used to interconnect the Virtual Connect Ethernet modules.
However, the following illustration provides recommended configurations for two, four, six, or eight
Virtual Connect Ethernet modules. A 10-Gb stacking link is already provided on the enclosure midplane
for horizontally adjacent Virtual Connect Ethernet modules (bays 1 and 2, 3 and 4, 5 and 6, or 7 and 8
of the c7000 enclosure, or bays 1 and 2, or 3 and 4 of the c3000 enclosure).
NOTE:
Port X0 is the 10Gb port connected through the midplane of horizontally-adjacent VC-
Enet modules. Port X7 and x8 connect to the internal link between horizontally-adjacent Flex-
10 enabled VC-Enet modules. These ports appear in the list of stacking link connections within
the user interface.
