Turn on the servers.
Connecting servers with a C2T chain
To share the same monitor, keyboard, and pointing device with several servers,
you must connect the servers together with Cable Chain Technology (C2T)
interconnect cables through the C2T (In) and C2T (Out) connectors.
The C2T chaining cable uses physically different shells and different-colored
connector covers (a black cover for out and a white cover for in) to prevent the
accidental connection of two C2T (Out) connectors.
Before you begin, review the following:
v
You can connect a maximum of 42 servers with the C2T chaining cables.
v
When connecting servers across a space larger than 3 U or on two separate
racks, you must use a C2T interconnect cable that is 2 m (6.5 ft) long, which is
available in the C2T option cable kit.
Note:
Only one 2-m (6.5 ft) cable can be used in the C2T chain.
v
The C2T chaining cables are hot-swappable.
Attention:
Do not let the pins of the C2T cable connectors touch the server
chassis when adding or removing systems to or from the C2T chain.
v
Servers are numbered by their position in the chain (1 through
n
). If one server
is removed from the chain, all successive servers are renumbered. For example,
if the twelfth server is removed from a chain of 15 servers, servers 13 through 15
will then be renumbered to 12 through 14.
v
The C2T numbering is independent of any other server reference. Changing the
position of the server in the C2T chain does not affect its IP addresses.
Complete the following steps to connect the servers:
1.
Gather several of the C2T cables.
Note:
Your server comes with a short C2T chaining cable that can span
approximately 3 U if needed. A longer C2T cable is available in the C2T
cable option kit.
2.
Connect the servers together:
a.
Connect one end of the C2T chaining cable to the C2T (Out) port of the top
server.
