The two 10/100/1000 ports are combination ports. When an SFP module is inserted it has priority over the 10/100/1000 port of the same number (25-26 on the Switch 3226, 49-50 on the Switch 3250). The corresponding 10/100/1000 port is disabled when an SFP module is present.
Switch — Front Figure 1 Switch 3226 — front view View Detail Figure 2 Switch 3250 — front view WARNING: RJ-45 Ports. These are shielded RJ-45 data sockets. They cannot be used as standard traditional telephone sockets, or to connect the unit to a traditional PBX or public telephone network.
If you disable auto-negotiation, Auto MDI/MDI-X will also be disabled. When an SFP module is inserted it has priority over the 10/100/1000 port of the same number (25-26 on the Switch 3226, 49-50 on the Switch 3250). The corresponding 10/100/1000 port is disabled when an SFP module is present.
Console Port The console port allows you to connect a terminal and perform remote or (Switch 3226) local out-of-band management. The console port uses a standard null modem cable and is set to auto-baud, 8 data bits, no parity and 1 stop bit.

NSTALLING THE This chapter contains the information you need to install and set up the Switch. It covers the following topics: Package Contents Choosing a Suitable Site Rack-mounting Placing Units On Top of Each Other The Power-up Sequence WARNING: Safety Information. Before installing or removing any components from the Switch or carrying out any maintenance procedures, you must read the safety information provided in Appendix A of this guide.
Water or moisture cannot enter the case of the Switch. Air flow is not restricted around the Switch or through the vents in the side of the Switch. 3Com recommends that you provide a minimum of 25mm (1in.) clearance. Air temperature around the Switch does not exceed 40 (104 °C...
Rack-mounting The Switch is 1U high and will fit in most standard 19-inch racks. CAUTION: Disconnect all cables from the Switch before continuing. Remove all self adhesive pads from the underside of the Switch if they have been fitted. To rack-mount your Switch: 1 Place the Switch the right way up on a hard flat surface, with the front facing towards you.

MDI port, you need to use a standard straight-through cable. See Table 7. 3Com recommends that you use Category 5 twisted pair cable — the maximum segment length for this type of cable is 100 m (328 ft).
CAUTION: If you want to install the Switch using a Category 5E or Category 6 cable, 3Com recommends that you briefly connect the cable to a grounded port before connecting network equipment. If you do not, the cable’s Electrostatic Discharge (ESD) may damage the Switch’s port.

If the SFP transceiver is faulty, it will not operate within the Switch. See “Solving Hardware Problems” on page 47. Use of non-3Com SFPs is not recommended. If the SFP transceiver is invalid it will not be recognized by the Switch.
7 Check the Module Active LEDs on the front of the Switch to ensure that it is operating correctly. Refer to “LEDs” on page 14 for more information. Removing an SFP If you wish to remove a 3Com transceiver (it is not necessary to Transceiver power-down your Switch): 1 Disconnect the cable from the transceiver.
ETTING Your Switch can operate in its default state, that is, you can install it and it will work straight away (plug-and-play). However, to make full use of the features offered by the Switch, and to change and monitor the way it works, you have to access the management software that resides on the Switch.

(Static IP addresses are necessary to ensure that the Switch is always allocated the same IP information.) For most installations, 3Com recommends that you configure the Switch IP information manually. This makes management simpler and more reliable as it is not dependent on a DHCP server, and eliminates the risk of the IP address changing.
