Note
Refer to
Chapter 6, “Installing and Removing a SPA,”
for information on removing and installing SPAs.
Removing a SIP
To remove a SIP from the line card chassis, see
Figure 5-4
and follow these steps:
Step 1
Attach an ESD-preventive wrist strap and follow its instructions for use.
Step 2
Identify the card to be replaced and unplug the interface cables connected to the card. Be sure to note
the current connections of the cables to the ports on the SPAs installed in the SIP.
Warning
Because invisible radiation may be emitted from the aperture of the port when no fiber cable is
connected, avoid exposure to radiation and do not stare into open apertures.
Statement 125
Note
You can also keep the dust caps or covers on the laser optical bores to avoid radiation exposure.
Step 3
Remove the SPAs from the SIP and set them aside.
Step 4
Loosen the two captive screws holding the SIP in place.
Step 5
Grasp the two card ejector levers and simultaneously pivot both ejector levers 90 degrees away from the
front edge of the card carrier to unseat the SIP from the backplane.
Step 6
Touching only the metal card carrier, slide the SIP from the slot and place it directly into an antistatic
sack or other ESD-preventive container.
Step 7
Insert another SIP, PLIM, or a PLIM impedance carrier into the empty card slot.
