Magnum 6K32 & 6K32T Managed Switch Installation and User Guide (12/05)

support of 10/100 and 1000Mb. The user can utilize the SNMP feature equipped with VLAN, Port security, 802.1X, and other security features to provide a secure and stable network as per the requirement

The 6K32T Managed Switch with NEBS Level 3 compliance and management flexibility allows the user more than one configuration alternative. The user has an advantage by fulfilling the present requirements as well as benefiting from the multiple choices of modules to support future expansion as the network evolves. The dual Gigabit port option in the modular slot boosts the bandwidth for high speed to support the peak traffic and minimize congestion.

Example 3 Redundant Application

In a redundant application for high network availability where a rack- mountable managed switch with over 24 ports is required with dense port features, Magnum 6K32T’s equipped with redundant LAN features like S-Ring, RSTP, Link- Loss-Learn and various security features are easily qualified for the application. The - 48VDC input power option with Dual Source is especially useful in telecom central offices.

The Magnum 6K32T with two Gigabit ports in the modular slot allows it to connect into a Gigabit mesh structure with an RSTP and S-Ring combination used in a no-single-point-of-failure self-healing LAN topology along with a ring of multiple 6K25s at the edge to allow the system to efficiently recover from a fault in the network. The industry standard Rapid Spanning Tree Protocol 802.1d is used in the top eight switches (see diagram below) to perform GB mesh fault recovery, whereas the bottom ring setup has been configured with S-Ring and Link-Loss-Learn for faster recovery in a big ring.

A redundant LAN setup not only provides a reliable recovery solution from network faults, but also improves operating up-time to simplify maintenance, save money and recover valuable time. In a critical application where secure data has been stored in a data mining storage facility, a redundant network provides a more secure solution.

The figure below has Magnum 6K32T’s and 6K25’s connected over the gigabit mesh structure for a high bandwidth secure redundant LAN setup.
