low-latency data path within the switch. The frame can be temporarily stored in the memory bank but only if the transmit port is busy. The switch is manufactured with eight universal ports (U_Ports). Universal ports provide the greatest amount of flexibility when building a fabric because the ports automatically and dynamically configure themselves to operate in E_Port, F_Port, or FL_Port mode during port installation. The ports negotiate from the FL_Port to the higher-performing F_Port if the attached device supports both modes. The embedded port, which is a logical N_Port, is based on a microcontroller and is responsible for: Fibre Channel link control Switch management Routing table management Address assignment and management functions Management of Class F services and the related protocols as defined in the Fibre Channel Standard The embedded port also functions as a Simple Network Management Protocol (SNMP) agent, a Fibre Channel Name Server, and an Alias Server to manage multicast and broadcast functions. Included with the switch is firmware that can be customized and tuned for each installation. Dell has provided a standard set of commands and interfaces described in "PowerVault 51F Commands" of the Dell PowerVault 51F 8-Port Fibre Channel Switch Installation and Troubleshooting Guide for switch monitoring, control, and management. The SWL fiber-optic GBIC module is based on short wavelength CD lasers supporting 1.0625-Gbps link speeds. This GBIC module supports 50-micrometer and 62.5-micrometer multimode fiber and is supported only in non-OFC (Open Fibre Connection) mode. 50/125-micrometer cables up to 500 meters (m) in length and 62.5/125-micrometer cables up to 175 m in length are supported. NOTE: The SWL GBIC module uses a Class 1 CD laser, which complies with the 21 CFR, subpart (J) as of the date of manufacture. 1-4 Dell PowerVault 51F 8-Port Fibre Channel Switch User's Guide
