Magnum 6K32 & 6K32T Managed Switch | Installation and User Guide (12/05) |
4.3Up-link Cross-over Switch on RJ-45 port modules, for port#1 only
The modular slot provided on Magnum 6K32T managed switch can be filled
with 6KP8-RJ45 port module among all the multiple choices of port modules. The upper part of the copper port module (6KP8-RJ45) has a manual Up-link switch, located on the inside of the unit on the port module board next to the RJ45 port # 1 which it controls. It enables the port’s cable to be cascaded (X) to a 10/100Mb repeater or switching hub in the network. The manual Up-link switch position is configured as (=) position as default factory setting, where used for all-copper module or combo modules.
4.4Auto-Cross (MDIX)Auto-negotiation, for 10/100Mbps RJ-45 ports
The 24 RJ-45 ports on Magnum 6K32T supports auto-cross (MDI or MDIX) in the auto-negotiation mode according to the IEEE 802.3u standard. No crossover cables are needed when connecting the 6K32T’s 10/100 copper ports to other unmanaged switches, legacy hubs, managed switches, media-converters etc. Please note that there can be conditions with managed switches where the switch manager fixes the port settings via software, and the result of the auto-negotiation is changed in the managed switch by the manager commands. In such cases, the 10/100 speed or the F/H mode may be affected, but auto-cross in the 6K32T Switches will still work. The auto-cross function can be disabled, if fixed the port at 10 or 100Mb through software..
The Managed Magnum 6K32T Fast Ethernet copper ports can be set for either fixed 100Mb speed or N-way auto-negotiation per the IEEE802.3u standard. The selection is made via 6K-MNS software. The factory default setting is for auto- negotiation. At 100Mb-fixed speed, the user may select half- or full-duplex mode by
6K-MNS Software for each RJ-45 port separately. For detail information see Section 7 (Port Setup) of Magnum 6K32T Software user guide (MNS-6K) . See Section (2.2.9 at
page no.13) of this manual to access the “MNS-6K Software user-guide”
One frequently-used application for the Managed 6K32T Switch copper ports is to connect one of them using a fiber media converter to another Switch in the network backbone, or to some other remote 100Mb device. In this case, it is desirable to operate the fiber link at 100Mb speed, and at either half- or full duplex mode depending on the capabilities of the remote device. Standard commercially available Fast Ethernet media converters mostly do not support auto-negotiation properly, and require that the switched port to which they are connected be at 100Mb fixed speed.
