INTRODUCTION
The SuperStack® II Baseline Switch is a flexible unmanaged switch that is very easy to use. It can be used to help build a small network or expand a larger, more established network.
The Baseline Switch has 12 dedicated RJ45 10BASE-T ports on the front panel and two RJ45 10/100 ports (ports 13 and 14) on the rear panel (which can both be either 10BASE-T or 100BASE-TX).
The Baseline Switch is suited for office use where it can be free standing, wall mounted, or rack mounted (in a wiring closet or equipment room). A mounting kit is supplied.
The unit can be powered either from the AC mains supply, or through an optional 3Com SuperStack II Advanced Redundant Power System. Contact your supplier for details.
The Baseline Switch comes with:
Network Connections
The Baseline Switch is ready to use, and can be used stand-alone or linked with other units, for example repeater hubs.
All ports on the Baseline Switch have full duplex auto-negotiation. Full duplex operation allows information to be transmitted and received simultaneously and, in effect, doubles the potential throughput of a link. If the device connected to a port supports auto-negotiation, the port operates in full duplex mode. Otherwise the port operates in half duplex mode.
CAUTION: The equipment that is connected to the Baseline
Switch must not be set up to operate in full duplex. Set it up to operate as auto-negotiate or half duplex.

Switching
When a network of repeater hubs is in operation, any information that is sent by the workstations is passed around the whole network (regardless of the destination of the information) which results in a lot of unnecessary traffic that can slow it down. The Baseline Switch solves this problem because it ‘listens’ to the network and automatically learns what workstations and network equipment can be reached through its ports. It can then selectively pass on any information by transmitting the traffic to the relevant port only
(instead of all ports like a repeater hub). This operation is called switching.
The Baseline Switch effectively segments your network, localizing the network traffic and passing on traffic as necessary. If you have workstations that communicate frequently in the same part of the network, traffic between them is not passed to the remainder of the network, reducing the load.
Connecting 10BASE-T and 100BASE-TX
The 10/100 ports allow you to connect 100BASE-TX networks or workstations to the Baseline Switch. This means that if you have both 10BASE-T and 100BASE-TX networks, you can connect them so that all your workstations can communicate.
Alternatively, if you have 10BASE-T and want to improve performance by introducing 100BASE-TX, the Baseline Switch protects your investment because it maintains 10BASE-T connections to your original network equipment.
Connecting 10BASE-T (Ethernet) Equipment
You can connect 10BASE-T units or DTE (workstations or other equipment) to any ports on the Baseline Switch. To connect your equipment, use 10BASE-T Category 3, 4 or 5 unshielded 100 Ohm TP or shielded (screened) 150 Ohm TP cable.
i |
Category 5 cable must be used with this product in |
structured wiring environments. This will ensure correct |
|
|
operation of all ports at 10Mbps or 100Mbps. |
Connect one end of the TP (twisted pair) cable to the RJ45 port on the Baseline Switch and the other end to the appropriate RJ45 port on the unit or DTE.
To remain within IEEE 802.3 10BASE-T rules, the maximum length of cable between the Baseline Switch and any DTE should not be greater than 100m (328ft). If you are connecting DTE to the Baseline
Switch through a series of repeaters, ensure that there are no more than four repeaters between the Baseline Switch and the DTE.
Connecting 100BASE-TX (Fast Ethernet) Equipment
You can connect 100BASE-TX units or DTE to ports 13 and 14 on the Baseline Switch. To connect your equipment, use 100BASE-TX
Category 5 unshielded 100 Ohm TP or shielded (screened) 150 Ohm TP cable.
Connect one end of the TP (twisted pair) cable to the RJ45 port on the Baseline Switch and the other end to the appropriate RJ45 port on the unit or DTE.
To remain within IEEE 802.3 100BASE-TX rules, the maximum length of cable between the Baseline Switch and any DTE should not be greater than 100m (328ft). If you are connecting DTE to the Baseline Switch through a series of repeaters, ensure that there are no more than two repeaters between the Baseline Switch and the DTE, and that the total cable length does not exceed 205m (672.4ft).
