Cisco 700-02226-01 enterprise networking (router/Catalyst switch/UCS families) Router Line Card

The Cisco 700-02226-01 is a blank filler panel designed to cover an empty WAN interface card (WIC) slot on a modular Cisco router chassis. WIC slots left open without a card or a blank panel fitted disrupt the chassis’s internal airflow path and can let dust and debris into the router, so Cisco specifies a panel like this for every unused slot on ISR and ISR G2 platforms that accept WIC, HWIC or VWIC modules. It is a simple mechanical part with no active electronics, but it is chassis-specific in its mounting and retention design, so it should be matched to the exact router family before fitting. Sites running a mix of Cisco 1800, 2800, 2900 or 3800/3900 Series routers, many with more WIC slots populated than cards fitted, keep a small stock of these panels for exactly this reason. Tech-Star (UK-based, shipped worldwide) stocks Cisco components to support ongoing network maintenance.
