Connecting the cable assembly connector
Note: Perform only one connection at a time. Do not remove the dust cover until
immediately prior to connection.
1. Clean the coupling by wiping the inside of the sleeve with a lint-free swab that has
been slightly moistened in alcohol. Then blow dry the coupling using compressed air.
2. Insert the connector into the coupling in such a manner that any connection/coupling
keying features are observed and properly mated.
3. Perform step and step with the second connector. If the second connector is not to
be installed, cover the open end of the coupling with a clean dust cap.
Disconnecting the cable assembly connector
1. Grasp the connector housing and disconnect the housing from the coupling.
2. Cover the connector and coupling ends with clean dust caps when not in use.
Port connection general information
This section contains general information about the port connections, fiber optic
connections, and copper connections to the SAN256N director.
N_Port connections
Connect Fiber Channel N_Ports to F_Ports on the switch. All 16 ports on the switch may
function as F_Ports. The switch automatically discovers which N_Port is connected to
which F_Port during the Fibre Channel login process as each N_Port is powered up.
Fiber Optic Connections
• Connect the transmit connector on the N_Port to the receive connector on the
assigned F_Port. Connect the receive connector on the N_Port to the transmit
connector on the assigned F_Port.
• Keys on “duplex” cable assemblies (a connector-pair containing both transmit and
receive fastened together in one unit), prevent you from connecting them incorrectly.
• On the HBA or device end consult the appropriate adapter or device manual to
determine the location of the transmit and receive connectors.
Fiber optic cable connection procedures
The following procedures describe how to connect the fiber optic cables to the SAN256N
director. These procedures must be performed in the order presented.
Before installing the fiber optic cables, verify that the SAN256N director power on self
test diagnostics ran successfully. You can do this by checking the TCM 16-character
display code. Refer to Appendix A. Data collection and troubleshooting on page 101 for
a list of display codes.
Fiber optic cable routing and connection for cabinet installations
To install the fiber optic cables to the SAN256N chassis TFIO blades (in cabinet):
Attention: Refer to safety notices before starting an installation.
