Removing a T1600 SFP
Small form-factor pluggables (SFPs) are transceivers that can be removed from a PIC.
SFPs are hot-insertable and hot-removable. Removing an SFP does not interrupt PIC
functioning, but the removed SFP no longer receives or transmits data.

To remove an SFP (see Figure 143 on page 253):
Place an electrostatic bag or antistatic mat on a flat, stable surface to receive the
1.
SFP. Have ready a rubber safety cap for the SFP transceiver and the cable.
Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect
2.
the strap to one of the ESD points on the chassis.
Label the cable connected to the SFP so that you can later reconnect it to the correct
3.
SFP.
Disconnect the cable from the SFP. Immediately cover the transceiver and the end
4.
of the cable with a rubber safety cap.
WARNING: Do not look directly into a fiber-optic transceiver or into the
ends of fiber-optic cables. Fiber-optic transceivers and fiber-optic cable
connected to a transceiver emit laser light that can damage your eyes.
CAUTION: Do not leave a fiber-optic transceiver uncovered except when
inserting or removing cable. The safety cap keeps the port clean and
prevents accidental exposure to laser light.
Arrange the cable in the cable management system to prevent it from dislodging or
5.
developing stress points. Secure the cable so that it is not supporting its own weight
as it hangs to the floor. Place excess cable out of the way in a neatly coiled loop in
the cable management system. Placing fasteners on the loop helps to maintain its
shape.
