2.2.6Gigabit (1000Mbps) port modules

The Magnum 6K32 offered a wide option Gigabit speed with multiple choice

for the modular slot. While up to two Gigabit modules (maxm.) can be configured in the modular slot. The Gigabit port option for the modular slot comes in couple of different configuration. The two Giga port has been offered as GBPM-2OTX (fiber or RJ-45), whereas the single Gigabit module comes in flavor of G+4(10/100 RJ-45 ports) or G+2 (100Mb fiber ports) as shown below in the figure.

The 6K32 modules provide a GBIC opening for insertion of industry-standard GBICs to provide Gigabit (Gb) media flexibility. GBIC models are available for both multi-mode (550m) and single-mode (10, 25, 40, 70)km fiber options, and for Gigabit copper as well, with new models appearing often.

The 1000Mb Gigabit fiber-port modules on the Magnum 6K32 are normally set (factory default) to operate at AUTO mode for best fiber distance and performance. The 1000Mbps SC fiber-optic module on the Gigabit -SX and Gigabit-LX transceivers are compatible with the IEEE 802.3z Gigabit standards.

There are two LEDs mounted on each Gigabit port module. The Gigabit fiber port is by default configured at AUTO mode, and can be fix at 1000Mbps speed full- duplex mode at any times and has LEDs that indicate LK (Link status) and ACT (receiving activity) on that port when lit.

2.2.7Packet 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 6K32 can do its part to prevent any QOS degradation while it is handling Ethernet traffic through its ports and buffers.

The Magnum 6K32 switching hardware supports the IEEE 802.1p standard and
