Apply the pads to the underside of each Switch, sticking one in the marked area at each corner. You can stack Switch units together in two ways: You can stack two Switch units with a single Matrix Cable. To do this: Stacking Two Units 1 Power-off both units. You only need one Matrix Module for each stack. This unit, which is also known as Page Choosing The Correct Cables cross-over. If you want to make a connection to another MDIX port, you need a cross-over cable.
Many ports on workstations and servers are configured as MDI straight-through. If you want to make a connection to an MDI port, you need to use a standard straight-through cable.
Page Managing The Switch Switch way it works. This management software is not required to get the Switch working, but if you do use it, you may improve the efficiency of the Switch and therefore improve the overall performance of your network. Page Safety Information You must read the following safety information before carrying out any installation or removal of components, or any maintenance procedures on the Switch FX.
Follow all directions carefully. The unit should never be connected to an A. This can only be achieved using the console port on the unit and an approved modem. Weight: 4kg 8.

Congestion is caused by devices sending traffic to already overloaded port on a Switch. Flow control prevents packet loss and inhibits devices from generating more traffic until the period of congestion ends. Page 55 A device that regenerates LAN traffic so that the transmission distance of that signal can be extended. Hubs are similar to repeaters, in that they connect LANs of the same type; however they connect more LANs than a repeater and are generally more sophisticated.
Page 56 Network Interface Card. A circuit board installed in an endstation that allows it to be connected to a network. An internal test that a Switch carries out when it is powered-up. The rules dictate format, timing, sequencing and error control. Page 57 LANs than a bridge and are generally more sophisticated. Switch Database A database that is stored by a switch to determine if a packet should be forwarded, and which port should forward the packet if it is to be forwarded.
Page 61 If it appears that any product that is stated to meet this standard does not perform properly with regard to such date data on and after January 1, , and Customer notifies 3Com before the later of April 1, , or ninety 90 days after purchase of the product from 3Com or its authorized reseller, 3Com shall, Response to requests for telephone technical support will be in the form of a return call from a 3Com representative by close of business the following business day.
These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This manual is also suitable for: 3c 3c - superstack ii switch 3ca - superstack ii switch Superstack ii Superstack ii fx 3c This manual is printed on paper that comes from sustainable, managed European forests. The production process for making the pulp has a reduced AOX level adsorbable organic halogen resulting in elemental chlorine-free paper.

Identify menu names, menu commands, and software button names. Status Green A link is present, and the port is enabled. Green flashing A link is present, but the port is disabled. The console port uses standard null modem cable and is set to auto-baud, 8 data bits, no parity and 1 stop bit. Page Network Configuration Examples Network Configuration Examples Network The following illustrations show some examples of how the Switch can be Configuration used in your network.
Figure 6 illustrates the key topology rules and provides examples of how they allow for large-scale Fast Ethernet networks. A m ft fiber run is allowed for connecting switch-to-switch, or endstation-to-switch, using half-duplex BASE-FX. A total network span of m ft is allowed in single-repeater topologies one hub stack per wiring closet with a fiber run to the collapsed backbone. Alternatively, the Switch can be rack-mounted in a wiring closet or equipment room.
You must use the screws supplied with the mounting brackets. Damage caused to the unit by using incorrect screws invalidates your warranty. The Matrix Port on the rear of the Switch allows you to connect two Switch units back-to-back. To stack up to four Switch units: 1 Power-off all the units.
If you want to make a connection to another MDIX port, you need a cross-over cable. Many ports on workstations and servers are configured as MDI straight-through.
If you want to make a connection to an MDI port, you need to use a standard straight-through cable. This management software is not required to get the Switch working, but if you do use it, you may improve the efficiency of the Switch and therefore improve the overall performance of your network.

They then use this information to forward packets based on their destination address. Congestion is caused by devices sending traffic to already overloaded port on a Switch.
Flow control prevents packet loss and inhibits devices from generating more traffic until the period of congestion ends.
