Notes on 7705 SAR-8 and 7705 SAR-F
The 7705 SAR-8 and the 7705 SAR-F run the same operating system software. The main
difference between the products is their hardware platforms.
The 7705 SAR-8 has an 8-slot chassis that supports two CSMs, a Fan module and six
adapter cards.
The 7705 SAR-F chassis has a fixed hardware configuration. The 7705 SAR-F replaces the
CSM, Fan module, and the 16-port T1/E1 ASAP Adapter card and 8-port Ethernet Adapter
card with an all-in-one unit that provides comparable functional blocks, as detailed in
Table 2.
The fixed configuration of the 7705 SAR-F means that provisioning the router at the “card
slot” and “type” levels is preset and is not user-configurable. Operators begin configurations
at the port level.
