Installing QSFP transceivers and cables
Follow these steps to install the QSFPs and cables in the FC16-64 port blades and 16-Gbps core
blades. In the core blades, these transceivers and cables are used to form the inter-chassis links (ICLs)
with neighboring DCX 8510 Backbones. The transceivers should be installed in the blades before
connecting the cables. Because each QSFP contains four 16-Gbps ports, be aware that any problems
with one port could affect all four ports in the quad if the QSFP must be replaced.
NOTE
Even though the installation and removal procedures are the same for QSFP ports in FC16-64 port
blades and the core blades, the physical QSFP transceivers designed for FC16-64 are not compatible
with the QSFP transceivers designed for the core blades. They are not interchangeable.
1. Position one of the QSFP transceivers so that the key is oriented correctly to the port. Insert the
transceiver into the port until it is firmly seated.
Transceivers are keyed so that they can only be inserted with the correct orientation. If a transceiver
does not slide in easily, ensure that it is correctly oriented.
When the transceiver is correctly seated, the status LED will flash amber several times and then turn
solid amber.
2. Remove the protective cap from the special QSFP cable and insert it into the transceiver until it is
firmly seated.
The cables are also keyed to fit into the transceivers correctly.
When the cable is correctly seated, the status LED will change from amber to green.
Repeat steps 1 and 2 for the remaining QSFP ports.
3. Organize the cables. Refer to Managing cables on page 42.
4. Verify the Brocade DCX 8510-4 and connector and port status using the switchShow -qsfp
command.
The following example is from a DCX 8510-4 with a core blade installed in slot 3.
Note that the State reported for an unconnected QSFP (shown QSFP 0 and Ports 0-3 in the example
is No_SigDet. This is different from the State of No_Synch that is reported for regular SFPs that are
unconnected.
QSFP 7 (ports 3/28-3/31, Index 748-751) in the following example shows the results for a connected
QSFP.
