Magnum 6K25 Managed Fiber Switch Installation and User Guide (04/06)

2.2 Product Description - Magnum 6K25 Managed Fiber Switch

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 heavy­duty 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

“Reverse” (with the ports and LEDs and the power-input and the management console
connector all in the rear and a duplicate set of LEDs in the front). Rack widths
accommodated include standard 19” RETMA, ETSI, and 23” Telco. Input power may be
AC, or –48VDC for Telco environments, or 24VDC for Industrial applications.

Designed for use in network traffic centers, the Magnum 6K25 Managed Fiber
Switches are easy to install and use. Addresses of attached nodes are automatically
learned, maintained and aged out, adapting the switching services to network changes.
LEDs provide status information on each port. The Magnum 6K25 provides high
performance plug-and-play hardware operation, 802.1p packet prioritization in hardware,
and industry-standard managed networks software functionality, all in convenient 1U
rack-mount packages.

2.2.1 Magnum 6K25 and 6K25R chassis

The Magnum 6K25 is a 19” rack-mountable Ethernet Switch with three eight­port slots (A, B, and C) and one Gb-only slot (D) for configuration flexibility. Slots A, B
and C may be configured with any of a large selection of fiber and copper port types and
combinations of types, typically eight ports per module, but sometimes 6 or 4 ports or
even one Gb port. Slot D may be configured with a Gb module that accepts GBICs. The
port types configurable using the 4 slots allows the 6K25 to efficiently serve a large
variety of applications, especially using fiber media. The Magnum 6K25 port modules
are normally factory installed, but may be changed or added in the field. (See Section 5)

Status LEDs are part of each port module and are viewable when connecting
the Ethernet media. A “regular” rack-mount 6K25 is shown in Figure 2.2.1a. On

status data is also available in software.

way auto-negotiating, and auto­crossover(MDIX) for operation at 10 or 100Mb speed in full- or half-duplex mode, i.e.,
each independently selects a mode and speed to match the device at the other end of the
twisted pair cable.

(See Section 4.3 for auto-negotiation and MDIX details). The auto-crossover feature will
automatically determine the other side of connection to make the connection, and
eliminate the need of cross-over cable.

On the model 6K8-RJ45 module, there are four LEDs for each port, two in the
connector and two separate. The LK (Link) LED indicates “ready for operation” on that
port when lit. The blinking ACT (Activity) LED indicates receiving Activity on that port
when lit. The 10/100 LED indicates operation at 100Mb speed when ON and at 10 Mb
speed when OFF (when auto­negotiation is not disabled).

auto-negotiation and fix the desired operation of each RJ-45 port. User may select 10Mb
or 100Mb speed and full- or half-duplex mode per-port as per user requirement. (See

The combo six-port modules are combinations of copper and fiber media, available as
four 10/100 switched RJ-45 copper ports and two 100Mb switched multi-mode fiber ST,
SC or single mode SC or Long Reach SC ports. For ports numbering, ports 1,3,5,7 are
copper, ports 2 and 6 are fiber, ports 4 and 8 are not present.

The four RJ-45 ports operate just like the 8-port copper module with auto-cross
(MDIX) feature to eliminate the use of cross-over cable, and the two fiber ports operate
at 100Mbps full-duplex (default). User mode control per port through the MNS software
is also the same.

On Magnum “4+2” Combo modules, there are four LED’s for each RJ-45 port,
which indicate status the same as described for the 6K8-RJ45 in Section 2.2.3 above. The
fiber port’s LEDs indicate status the same way as described for the SFF fiber modules in
Section 2.2.2 above. Color-coding on the panel of the module shows which LEDs
belong to which port.
