    • Described are a system and method for initializing a traffic card in a network element after a restart. The traffic card receives status information regarding a shelf processor card over a low-level link. If the status information indicates that the shelf processor card is unavailable, the traffic card supports traffic using provisioning data stored at the traffic card. Otherwise, if the status information indicates that the shelf processor card is un-initialized or initializing, the traffic card waits for the shelf processor card to be available. If the shelf processor is operational, the traffic card communicates with the shelf processor card to determine which provisioning data to use. When restarting the card, boot code stored in a first memory bank is executed. If this boot code is determined to be invalid, execution is redirected to boot code stored in a second memory bank to continue the restart process of the card.
    • 描述了在重新启动之后初始化网络元件中的交通卡的系统和方法。 交通卡通过低级链路接收关于货架处理器卡的状态信息。 如果状态信息指示货架处理器卡不可用,则交通卡支持使用存储在交通卡处的供应数据。 否则,如果状态信息指示货架处理器卡未初始化或初始化,则交易卡等待货架处理器卡可用。 如果货架处理器可操作,则交通卡与货架处理器卡通信以确定要使用的供应数据。 当重新启动卡时,执行存储在第一存储体中的引导代码。 如果该引导代码被确定为无效,则执行被重定向到存储在第二存储体中的引导代码,以继续重新启动卡。
