The Magnum Managed Fiber Switch boosts the performance of large Ethernet 

LANs, typically serving as a “backbone” switch.  It has the flexibility to handle a mix of 

both fiber and twisted-pair switched ports along with Gigabit backbone port options. 

Industry-standard IEEE 802.1p QOS prioritization is included, providing high 

performance switching services for both “smooth” streaming and “bursty” data traffic. 

The Magnum 6K25 has up to 25 ports capacity, all of which may be configured 

as fiber ports, but still offers a space-saving rack-mount chassis that is only 1U (1.70in. 

or 4.32cm) high. The “mixed-media” capability allows user selection of all popular 

flavors of fiber port connectors and modes, including even 10Mb fiber along with 

Gigabit ports.  It also allows a mix of 10/100Mb RJ-45 (copper) ports and a fiber Gigabit 

port in the same unit.  This flexibility is achieved via a family of 6K25 port modules for 

copper and fiber-built-in (emphasizing Small Form Factor fiber for high fiber port 

density), 6-port modules for fiber and RJ-45 combinations, and 1Gb port module 

selections using GBICs.  These modules can be factory configured in a base chassis unit 

(or may be changed in the field by trained technicians) to adapt the unit to the user’s 

application and Ethernet cabling requirements. Even evolving mixed-media requirements 

for 10Mb and  100Mb fiber and copper as well as Gigabit ports can be handled by the 

Magnum 6K25  product.  

The 6K25 managed switches also provides PoE option via Power-pass-through and 

power –inside PoE modules and  allows the users to select a wide option of combo PoE 

modules to support 802.3af pd devices. See details in sec 5.2.10 and 5.2.11. The Power 

Sourcing Equipment (PSE), and are fully compatible with Powered Devices (PD)(e.g 

wireless access points, IP phones) that comply with the IEEE 802.3af PoE standard. The 

PoE switch ports have an auto-sensing algorithm, so that they provide power only to 

802.3af, PoE end devices.  PoE is managed by a multi-stage handshake to protect 

equipment from damage and to manage power budgets .The PoE ports will 

discontinue supplying power when the PoE powered devices are disconnected, and 

support the 802.3af  PoE PSE standard for over-current protection, under-current 

detection, and fault protection.  

The packaging and power-input options target the Magnum 6K25 at heavy-

duty applications.  The chassis mounting rack style may be “regular” (with the ports and 

LEDs in the front and the power input and management console connector in the rear) or
