How to Install or Remove a Small Form-Factor Pluggable (SFP) Module
Replacing a SFP on a Line Card that Uses an Articulated Bracket
To replace a failed, defective, or retired SFP from a line card that is currently in service, and using an
articulated cable management bracket, proceed as follows:
Step 1 For a line card with multiple articulated brackets, select the fibers to be removed from the bracket with
the SFP to be removed.
For a line card with a single articulated bracket, begin with Step 2.
Step 2 Undo and remove the Velcro from the articulated bracket to release the fibers.
Step 3 From the physical location of the SFP to be removed, determine which end of the articulated bracket will
be unscrewed:
• For the upper half of the line card, remove the top screw.
• For the lower half of the line card, remove the lower screw.
• If there is any interference with another installed bracket, choose the other screw location.
Step 4 Pivot the articulated bracket up or down, depending on which screw was removed.
Step 5 Label and disconnect the fibers from the port and put them aside.
Step 6 Remove the SFP.
Step 7 Replace with the new SFP (or a dust cap if the port is not going to be reused).
Step 8 Re-install the fibers that were removed in Step 5 per the labels.
Step 9 Pivot the articulated bracket back into position and secure.
Step 10 Re-dress and secure the fibers to the articulated bracket with Velcro.
