2.2 Product Description - Magnum 6K25e 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 6K25e 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

Magnum 6K25e Gigabit Fiber Switch Installation and User Guide (10/07)
Gigabit port in the same unit. This flexibility is achieved via a family of 6K25e 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 6K25e product.

The 6K25e 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 6K25e 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 6K25e 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 6K25e 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.

Magnum 6K25e Gigabit Fiber Switch Installation and User Guide (10/07)

2.2.1 Magnum 6K25e and 6K25eR chassis

The Magnum 6K25e is a 19” rack-mountable Ethernet Switch with three
eight-port 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 6K25e to efficiently
serve a large variety of applications, especially using fiber media. The Magnum 6K25e
port modules are normally factory installed, but may be changed or added in the field.
(See Section 5)

Figure 2.2.1a: “Regular” 6K25e front view, configured for 24 +1 Gb ports

Status LEDs are part of each port module and are viewable when connecting
the Ethernet media. A “regular” rack-mount 6K25e is shown in Figure 2.2.1a. On
“Reverse” rack-mount models, there is a duplicate set of LEDs on the other (front) side
for normal status viewing from that direction. Of course, with management, the port
status data is also available in software.

The 100Mb fiber eight-

6K25e’s normally are set (factory
default) to operate in full-duplex mode for best fiber distance and performance. Using the
6K25e’s MNS software, the user may select full- or half-duplex mode per-port through
set-up of the software (See Magnum 6K25e MNS Software Manual) for the flexibility to
adapt to any FDX or HDX type of Fast Ethernet devices).

There are three LED’s per fiber port. The Link (LK) LED indicates “ready for
operation” on that port when lit, the F/H LED indicates operation in full-duplex mode
when ON (half-duplex when OFF), and the blinking ACT LED indicates receiving
Activity on the port. A fiber cable must be c onne c ted into a SFF port and the Link (LK)
indicator for that port must be ON (indicating there is a powered-up device at the other

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

Using the 6K8-Series (MNS-6K) management software, the user may disable
auto-negotiation and fix the desired operation of each RJ-45 port. User may select 10Mb

2.2.9 Packet Prioritization, 802.1p QOS

Quality of Service means providing consistent predictable data delivery to

users from datagram paths that go all across a network. As a LAN device, the Magnum
6K25e can do its part to prevent any QOS degradation while it is handling Ethernet
traffic through its ports and buffers.

The Magnum 6K25e switching hardware supports the IEEE 802.1p standard
and fulfills its role in support of QOS, giving packet processing priority to priority tagged
packets according to the 802.1p standard. In addition to hardware support for QOS, the
MNS software (R2) supports two priority queues that can be shared across the eight
levels of defined packet priorities for application-specific priority control by the user
through software configuration settings.

2.2.10 Frame Buffering and Flow Control

Magnum 6K25e’s are store-and-forward switches. Each frame (or packet) is

loaded into the Switch’s memory and inspected before forwarding can occur. This
technique ensures that all forwarded frames are of a valid length and have the correct
CRC, i.e., are good packets. This eliminates the propagation of bad packets, enabling all
of the available bandwidth to be used for valid information.

While other switching technologies (such as "cut-through" or
"express") impose minimal frame latency, they will also permit bad frames to propagate
out to the Ethernet segments connected. The "cut-through" technique permits collision
fragment frames (which are a result of late collisions) to be forwarded which add to the
network traffic. Since there is no way to filter frames with a bad CRC (the entire frame
must be present in order for CRC to be calculated), the result of indiscriminate cut­through forwarding is greater traffic congestion, especially at peak activity. Since
collisions and bad packets are more likely when traffic is heavy, the result of store-and­forward operation is that more bandwidth is available for good packets when the traffic
load is greatest.

When the Magnum 6K25e Switch detects that its free buffer queue space is
low, the Switch sends industry standard (full-duplex only) PAUSE packets out to the
devices sending packets to cause “flow control”. This tells the sending devices to
temporarily stop sending traffic, which allows a traffic catch-up to occur without
dropping packets. Then, normal packet buffering and processing resumes. This flow­control sequence occurs in a small fraction of a second and is transparent to an observer.

Another feature implemented in Magnum 6K25e Switches is a collision-based flow­control mechanism (when operating at half-duplex only). When the Switch detects that
