The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

This chapter describes how to install or remove SIPs on the Cisco CRS-1 router. This chapter contains the following sections:
Each SIP is mounted to a metal carrier and is sensitive to electrostatic discharge (ESD) damage. Before you begin installation, read the Preparing to Install a SIP or a SPA. for a list of parts and tools required for installation.
Caution | Always handle the SIP by the carrier edges and handle; never touch the SIP components or connector pins (see the figure below). |
A PLIM impedance carrier must be installed in each empty PLIM slot in the Cisco CRS-1 router chassis (see see the figure below). The impedance carrier preserves the integrity of the chassis and is required for EMI compliance and proper cooling in the chassis.
Guidelines for SIP installation and removal include the following:
1 |
Captive screw |
2 |
Ejector lever |
Caution | When you remove a SIP, always use the ejector levers to ensure that the connector pins disconnect from the midplane in the sequence expected by the router. |
Caution | The router can indicate a hardware failure if you do not follow proper procedures. Remove or install only one SIP or PLIM at a time. Wait at least 15 seconds before removing or installing another SIP or PLIM. |
This section contains the following procedures:
Note | Refer to the Installing and Removing a SPA for information on removing and installing SPAs. |

This section provides step-by-step instructions for installing a SIP. You can install a SIP in any slot not occupied by a Route Processor (RP) card (or a fan controller card on the 16-slot chassis only). If you install a new MSC or SIP, you must first remove the PLIM impedance carrier card from the available slot.
Caution | The system can indicate a hardware failure if you do not follow proper procedures. Remove or install only one SIP or PLIM at a time. Allow at least 15 seconds for the system to complete the preceding tasks before removing or installing another SIP or PLIM. |
During this procedure, wear grounding wrist straps to avoid ESD damage to the card. Do not directly touch the backplane with your hand or any metal tool, or you could shock yourself. Statement 94
To install a SIP, follow these steps:
Step 1 | Attach an ESD-preventive wrist strap and follow its instructions for use. | ||||
Step 2 | Remove the SIP from its antistatic packaging. | ||||
Step 3 | Remove the PLIM
or PLIM impedance carrier from the slot you need to fill and set it aside.
| ||||
Step 4 | Grasp one of the septums that separate the SPA slots or one of the ejector levers with one hand and place your other hand under the SIP to support and guide it into the correct slot. Slide the card halfway into the correct slot. Avoid touching the card circuitry or any connectors. | ||||
Step 5 | Pivot both card
ejector levers so the openings on the card ejector cams at the top and bottom
of the SIP pass over the tabs on each side of the card cage slot.
| ||||
Step 6 | Continue
sliding the SIP into the card cage slot until the openings on the card ejector
cams engage the tabs on each side of the card cage slot.
| ||||
Step 7 | To seat the card in the midplane connector, grasp both card ejector levers and pivot them inward toward the handle in the card carrier until they are flush against the front edge of the card carrier. | ||||
Step 8 | Engage both
captive screws on the PLIM, and then tighten the screws. Tighten the locking
thumbscrews on both sides of the SIP to a torque of between 8.3 and 11
inch-pounds (94 to 124 N-cm). Do not overtighten.
| ||||
Step 9 | Install the SPAs. See the SPA Installation and Removal section. | ||||
Step 10 | Install the interface cables. We recommend that you clean the fiber-optic connections before attaching the cables. See http://www.cisco.com/c/en/us/td/docs/routers/crs/maintenance/optics/maintenance/guide/crs_opt.html for cleaning instructions. | ||||
Step 11 | If this SIP is
new, configure it for operation. For instructions, see
Cisco IOS XR
Interface and Hardware Component Configuration Guide for your software
release. For command syntax, refer to
Cisco IOS XR
Interface and Hardware Component Command Reference.
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
