blocking) on Full-Duplex ports, which provides for a “PAUSE” packet to be transmitted 

to the sender when the packet buffer is nearly filled and there is danger of lost packets. 

The transmitting device is commanded to stop transmitting into the 6K32F’s Switch port 

for sufficient time to let the Switch reduce the buffer space used. When the available 

free-buffer queue increases, the Switch will send a “RESUME" packet to tell the 

transmitter to start sending the packets. Of course, the transmitting device must also 

support the 802.3x flow control standard in order to communicate properly during 

normal operation. 

Note: When in Half-Duplex mode, the 6K32F’s Switch implements a back-pressure 

algorithm on 10/100 Mb ports for flow control. That is, the switch prevents frames from 

entering the device by forcing a collision indication on the half-duplex ports that are 

receiving. This temporary “collision” delay allows the available buffer space to improve 

as the switch catches up with the traffic flow. 

This chapter describes each Port Module (PM), including appearance, 

functionality, and status displays. 

This section applies only to PMs shipped as separate items, i.e., 6K32F Series 

PMs not factory installed in a Magnum 6K32F modular slot. 

 

 

Examine the shipping container for obvious damage prior to 

installing a 6K32F Series PM; notify the carrier of any damage you believe 

occurred during shipment or delivery.  Inspect the contents of this package for 

any signs of damage and ensure that the items listed below are included. 

 

This package should contain: 

6K32F Series PMs 

Installation instructions, with illustrations 

 

 

Remove the 6K32F Series PM(s) from the shipping container. Be sure to keep 

the shipping container should you need to ship any of the PMs separately at a 

later date. In the event there are items missing or damaged, contact your 

supplier. If you need to return the unit, use the original shipping container if 

possible. Refer to Chapter 5 for specific return procedures.

An important feature of the Magnum 6K32F Series is the use of one Port 

Module for flexible mixed-media connectivity to RJ-45 and fiber media in the
