Important: Note that all application and line cards are hot swappable. This means that you can install or remove cards from the chassis without powering the chassis down. However, it is strongly recommended that you add system components during a maintenance window.
Important: In ASR 5000 systems, you must install the System Management Cards (SMCs) in slots 8 and 9. Their associated line cards are the Switch Processor Input Output card (SPIO) and the Redundant Crossbar Card (RCC). Assure that the SPIOs are installed in slots 24 and 25, and the RCCs are installed in slots 40 and 41 to prevent damage to the cards or the chassis midplane.
Important: In ASR 5000 systems, the 10 Gigabit Ethernet Line Card (XGLC) is a full-height line card that takes up the upper and lower slots in the back of the chassis. When referring to installed XGLCs, use the upper slot number only. Slot numbering for other installed half-height cards is maintained: 17 to 32 and 33 to 48, regardless of the number of installed XGLCs
Important: If you are adding PSCs, PSC2s, PSC3s or PPCs to a live system, it is recommended that you add them two at a time. This evenly distributes software tasks between the CPUs on the cards for optimal performance. You can add single packet processing cards to a production system. However, you must reboot the system to ensure optimal operation and capacity. For this reason Cisco Systems suggests that you perform the installation during a maintenance window when a reboot will have minimal impact.
ESD Caution: During installation, maintenance, and/or removal, wear a grounding wrist strap to avoid ESD damage to the components. Failure to do so could result in damage to sensitive electronic components and potentially void your warranty.|
Step 2
|
Determine which chassis slot to install the card in based on the information in the Chassis Slot Numbering and Assignments section in this guide.
|
Important: To achieve optimal airflow performance in minimal system deployments, populate packet processing cards from the middle of the chassis outward, leaving an empty slot between them. For example, with four packet processing cards use slots 3, 5, 12, and 14. For two packet processing cards, place them in slots 5 and 12.|
Step a
|
Caution: Do not leave chassis slots uncovered for extended periods of time. This reduces airflow through the chassis and could cause it to overheat. Make sure there is a circuit card or blanking panel in every chassis slot at all times. 
Caution: Take extra care when you install packet processing cards. These cards contain heat sinks that could become loose or damaged if they come into contact with an adjacent card while the packet processing card is being inserted in the chassis slot.
Important: If you are installing PSCAs in a chassis that contains PSCs, refer to the Chassis Hybrid Mode Operation appendix for additional configuration information.
Important: Make sure the interlock switch is fully raised in order to properly secure the application card’s top screw to the chassis.
Warning: To reduce the risk of electric shock and ensure proper ventilation, blanking panels must be used to cover any chassis slot not occupied by an application card. Leere Steckplaetze muessen mit der dafuer vorgesehenen Abdeckplatte geschlossen werden, um die Luftzirkulation innerhalb des Geraets zu gewaehrleisten und um einen elektrischen Schlag zu vermeiden.

XGLC SR: Accepts a 10GBase-SR module for a fiber optical cable with a center wavelength of 850nm terminated by an LC connector. It can drive an optical signal up to 300 meters using 50/125um fiber (MMF), and up to 33 meters using 62.5/125um fiber (MMF).

Step 6

Remove the half-height card guide separating the exposed upper and lower chassis slots. Save all of the items you remove in this step in the event that you wish to re-populate these slots with half-height cards at a later time.

Important: You may need to slightly angle the guide when you slide it out of the chassis to unlatch it.
Important: The interlock switch must be fully raised to properly secure the line card’s top screw to the chassis.
