Installing QSFP transceivers
Follow these steps to install the QSFPs and cables in the 16 Gbps core blades. These transceivers and cables are
used to form the inter-chassis links (ICL) 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 has to be replaced.
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 ICL
3. Organize the cables See "Managing Cables."
4. Verify the Brocade DCX 8510-8 and connector and port status using the switchShow -qsfp command.
A sample of the command output is shown below. The example is from a DCX 8510-4 with a core blade installed
in slot 3. Some details for the 8510-8 will be different, but the reported information for the QSFPs will be similar.
Note that the State reported for an unconnected QSFP (shown QSFP 0 and Ports 0-3 below) 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.
