Removing and Installing a SIP
Figure 4-2 SIP Removal and Installation
Caution
When you remove a SIP, always use the ejector levers to ensure that the SIP connector pins disconnect
from the backplane in the logical sequence expected by the router. Any SIP that is only partially
connected to the backplane can halt the router.
Step 5
Simultaneously pivot the ejector levers away from each other to release the SIP from the backplane
connector. (See
Figure 4-2 .)
Step 6 Grasp the ejector levers and pull the SIP halfway out of the slot.
Step 7
Grasp the SIP by the handle and gently pull it straight out of the slot, keeping your other hand under the
SIP to guide it. (See
Figure 4-2 .) Avoid touching the SIP printed circuit board, components, or any
connector pins.
Step 8 Place the removed SIP on an antistatic mat, or immediately place it in an antistatic bag if you plan to
return it to the factory.
Step 9
If the SIP slot is to remain empty, install a line card blank (Product Number MAS-GSR-BLANK) to keep
dust out of the chassis and to maintain proper airflow through the SIP compartment. Secure the SIP blank
to the chassis by tightening its captive screws.
