H/S PERIPHERAL SHELF FRONT COVER The High Speed Peripheral Shelf front cover is an optional assembly for the High Speed Peripheral Shelf (90-2291-01). It is required for European Union EMC Class B compliance. (Note that Class B compliance is normally required for locations which are other than telecommunications centre ; if the location is a telecommunications centre, then the HSPS front cover may not be required.) The H/S Peripheral Shelf front cover is field installable, and the kit consists of mounting brackets, shelf cover and instructions for installation. The cover is perforated to allow all LEDs to be visible through the perforations. Locking clips at the top of the cover allow the cover to be removed to enable access to the OC12 line cards and FICs.
