• System Management Card (SMC): The Session Management Card (SMC) is used with the packet processing cards (PSC, PSC2, or PPC) in the ASR 5000 hardware platform. It serves as the primary controller, initializes the entire system, and loads the software’s configuration image into other cards in the chassis. Up to two SMCs can be installed in the chassis: one primary and one redundant “hot-standby” card. Chassis slots 8 and 9 are reserved for the SMC only. By default, when the chassis’ power is on, the SMC in slot 8 is active. The other SMC is automatically placed into standby mode.Caution: Do not place any card other than an SMC into slots 8 or 9 of the ASR 5000. To do so will cause damage to the card and may cause damage to the chassis' midplane.
• Packet Services Cards (PSC, PSC2, and PPC): The packet services cards are used with the System Management Card (SMC) in the ASR 5000 hardware platform. These cards provide the packet processing and forwarding capabilities within a system. Each packet processing card type supports multiple contexts, which allows you to overlap or assign duplicate IP address ranges in different contexts. The minimum recommended dedundancy for packet services cards is one redundant card for up to 13 active cars.
Important: To achieve optimal airflow performance in minimum system deployments, populate packet services cards into the chassis from the middle of the chassis outward. Leave an empty slot between the cards, when possible. For example, for four PSCs, use slots 3, 5, 12, and 14. For two PSCs, use slots 5 and 12. For more detailed information on SMCs and packet processing card types, refer to the Hardware Platform Overview chapter.
Important: This configuration does not include the required line cards. Line cards are discussed in Line Card Installation in this guide.
ESD Caution: During installation, maintenance, and/or removal, wear grounding wrist and/or heel straps to avoid ESD damage to the components. Failure to do so could result in damage to electrical components and could potentially void your warranty.
Caution: To avoid damaging the interlock switch, ensure that it is completely down before proceeding. For additional information, refer to the Hardware Platform Overview chapter. In addition, take extra caution when installing packet processing cards. These cards contain heat sinks that could become loose or damaged if they come into contact with another card while the packet processing card is being inserted in the chassis slot.
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 to ensure proper ventilation, blanking panels must be used to cover any chassis slot that is 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.
