7850 Extension Switch Hardware Installation Guide
•
Plan for the rack space required for cable management before installing the switch.
•
Leave at least 1m (3.28 ft) of slack for each port cable. This slack 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 Brocade ISL Trunking, consider grouping cables by trunking groups. The cables that are used in
trunking groups must meet specific requirements, as described in the Brocade Fabric OS Administration 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 transceivers that are qualified for Brocade products. For current information on qualified
transceivers supported by this device, refer to the Brocade Transceiver Support Matrix and the Brocade Transceiver
Modules webpage on www.broadcom.com. If you use an unqualified transceiver, theswitchshow command output
shows the port in a Mod_Inv state. The issue is also logged in the system error log.
Perform the following steps to insert an SFP+ transceiver.
NOTE
•
Always use the pull tab to insert or remove a transceiver, because the transceiver might be hot.
•
You might find it easier to insert the cables into the transceiver first and then install the transceiver.
1. Use the pull tab on the SFP+ transceiver to help push the transceiver into the port.
Transceivers are keyed so that they can be inserted only 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.
