Online Insertion and Removal
Cisco XR 12000 Series Router SIPs and SPAs support online insertion and removal (OIR). SPAs can be
inserted or removed independently from the SIP. OIR of a SIP with installed SPAs is also supported.
SPA Installation and Removal
You can install one single-width SPA in an SIP. This section provides step-by-step instructions for
removing and installing a SPA in an SIP.
Warning When performing the following procedures, wear a grounding wrist strap to avoid ESD damage to the
SPA. Some platforms have an ESD connector for attaching the wrist strap. Do not directly touch the
midplane or backplane with your hand or any metal tool, or you could shock yourself.
To remove and install a SPA in an SIP, refer to Figure 5-2 and do the following:
Step 1
To insert the SPA in the SIP, locate the guide rails inside the SIP that hold the SPA in place. They are at
the top left and top right of the SPA slot and are recessed about an inch, as shown in C of
Figure 5-2 .
Step 2 Carefully slide the SPA all the way in the SIP until the SPA is firmly seated in the SPA interface connector.
When fully seated, the SPA might be slightly behind the SIP faceplate.
Step 3
After the SPA is properly seated, turn the SPA lock to its locked and horizontal position, as shown in A
of
Figure 5-2 .
Step 4 To remove the SPA from the SIP, turn the SPA lock from its locked and horizontal position shown in A
of
Figure 5-2 to its unlocked and vertical position shown in B of Figure 5-2 . (If the SIP is still in the
router, you must remove the SIP before removing a SPA.)
Step 5
Grasp the handle of the SPA and pull the SPA from the SIP. (You have already disconnected the cables
from the SPA when removing the SIP).
