2.2.6Gigabit (1000Mbps) port modules

The Magnum 6K8-Series offers a wide range of optional Gigabit modules and

one or two Gigabit ports can be configured in one modular slot. The Gigabit modules are the two port GBPMV-2OTX , the 6KP5V-G4RJ (single Gigabit+4 10/100 RJ-45 ports) or the 6KP3V-G2SC (single Gigabit+2 100Mb fiber ports) as shown below in the figure.

The 6K82 -Series Modules provide6 a GBIC opening for insertion of industry-standard GBICs to provide Gigabit media flexibility. GBIC models are available for both multi- mode (550m) and single-mode (10, 25, 40, 70) km fiber options. Gigabit copper is also available with new models appearing often.

The 1000Mb Gigabit fiber-port modules on the Magnum 6K8-Series 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 to AUTO mode, and can be fixed at 1000Mbps speed full- duplex mode at any time. The Gigabit fiber port has LEDs that indicate LK (Link status) and ACT (receiving activity) on that port when lit.

NOTE: For detail information about the various port module 6KPMV options being used for Magnum 6K8, please check section5.2, 6KPM Module Description.

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 6K8-Series can do its part to prevent any QOS degradation while it is handling Ethernet traffic through its ports and buffers.
