ASR 5000系列机箱PSC放置和配置要求适当的线路卡功能的
简介
本文关于放置和配置描述信息包服务卡(PSC)需求，必须满足为了保证所有线路卡是可用的在Cisco聚合服务路由器(ASR) 5000系列机箱。
PSC配置和放置需求
有PSC放置和配置的一些需求关于线路卡作用。您也许发现，当您尝试配置一个线路卡端口用端口以太网时，您遇到失败：没有这样Port错误信息。
为了请是的线路卡能在它后可用的， PSC必须物理的安排其模式配置作为激活。如果PSC配置作为备用模式，即使有足够的PSCs配置同能连接到它的激活模式，则线路卡不是可用的并且报告READY状态。这适用于大型的XGLC (万兆以太网线路卡)和半尺寸线路卡。这是最佳解释与使用示例。
在本例中，起点是七出于作为激活模式配置的八个PSCs，并且PSC 16配置作为备用模式。另外， PSC 16通过更早的迁移做激活。注释线路卡32的状态在下输出中，物理的连接对PSC 16 (16 + 16 = 32)并且在READY状态。这是因为PSC 16配置作为备用模式。

之后， PSC 16配置对激活模式：
[local]ASR5000-2(config)# card 16
[local]ASR5000-2(config-card-16)# mode active
[local]ASR5000-2(config-card-16)# end
这造成PSC 4过渡到激活模式，因为由设计系统尝试激活是配置的活跃的许多个PSCs。它也造成线路卡32过渡到备用状态，允许它将配置/使用和连接对PSC 16 ：
