Installing an SFP+ transceiver
• Plan for rack space required for cable management before installing the switch.
• Leave at least 1 m (3.28 ft) of slack for each port cable. This provides room to remove and replace
the switch, allows for inadvertent movement of the rack, and helps prevent the cables from being
bent to less than the minimum bend radius.
• If you are using ISL Trunking, consider grouping cables by trunking groups. The cables used in
trunking groups must meet specific requirements, as described in the Fabric OS Administrator’s
Guide .
• For easier maintenance, label the fiber-optic cables and record the devices to which they are
connected.
• Keep LEDs visible by routing port cables and other cables away from the LEDs.
• Use hook and loop style straps to secure and organize fiber-optic cables.
Installing an SFP+ transceiver
The device supports only Brocade-qualified transceivers. If you use an unqualified transceiver, the
switchshow command output shows the port in a Mod_Inv state. Fabric OS also logs the issue in the
system error log. To insert an SFP+ transceiver, complete the following steps:
NOTE
The 16- and 32-Gbps SFP+ transceivers do not have bails. Always use the pull tab to insert or remove
the transceivers, as the SFP might be hot.
1. Use the pull tab on the 16- and 32-Gbps SFP+ transceivers to help push the transceiver into the port.
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. Push the correctly oriented transceiver
into the port until it is firmly seated and the latching mechanism clicks.
NOTE
Each SFP+ transceiver has a 10-pad gold-plated PCB-edge connector on the bottom. The correct
position to insert an SFP+ transceiver into the upper row of ports is with the gold edge down. The
correct position to insert an SFP+ transceiver into the lower row of ports is with the gold edge up.
