14 CHAPTER 1: INTRODUCING THE SUPERSTACK 3 SWITCH 4400

About the Switch The Switch 4400 is a stackable 10/100 Mbps Ethernet switch and 4400 provides high-performance workgroups with a backbone to server

connection. The Switch 4400 allows Cascade, Gigabit Ethernet or Fast Ethernet Fiber connections when expansion modules are installed in the expansion slots on the rear of the unit. You can also add the Switch 4400 to any SuperStack® system as your network grows.

The Switch 4400 PWR (3C17205) supports Power over Ethernet on all front panel ports. If you plug in a compatible (IEEE 802.3af compliant) device, it will be automatically detected and power supplied to it. Power over Ethernet is enabled on each port by default.

The Switch 4400 FX (3C17210) has 24 100BASE-FX MT-RJ ports. These allow easy connection of 100 Mbps fiber-optic links.

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. Only connect RJ-45 data connectors, network telephony systems, or network telephones to these sockets.

Either shielded or unshielded data cables with shielded or unshielded jacks can be connected to these data sockets.

10BASE-T/ The Switch 4400, 4400 SE and 4400 PWR have 24 or 48

100BASE-TX Ports auto-negotiating 10BASE-T/100BASE-TX ports configured as Auto MDIX (cross-over). These ports automatically provide the appropriate connection. Alternatively, you can manually set these ports to 10BASE-T half duplex, 10BASE-T full duplex, 100BASE-TX half duplex or 100BASE-TX full duplex. The maximum segment length is 100 m (328 ft) over Category 5 twisted pair cable.

The 4400 PWR will supply up to 15.4W of power through any of the 24 front panel ports in conformance to the 802.3af specification. The Switch 4400 PWR incorporates a LED Mode Button on the front panel, which when pressed changes the mode of the front panel port LEDs functionality between Switch and Power mode.

100BASE-FX Ports The Switch 4400 FX has 24 100BASE-FX MT-RJ ports. These are

100 Mbps fiber-optic ports that can use standard multi-mode fiber-optic cable of up to 2 kilometers (1.2 miles). They use the standard MT-RJ

Power Socket The Switch automatically adjusts its power setting to any supply voltage in the range 90-240 VAC.

Redundant Power To protect against internal power supply failure, you can use this socket System Socket to connect a Switch 4400 to a SuperStack 3 Advanced Redundant Power

System (RPS). See “Connecting a Redundant Power System” on page 30.

Console Port The console port allows you to connect a terminal and perform remote or 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.

Expansion Module You can use these slots to install Expansion Modules. These allow the Slots Switch to support various forms of connection and add extra functionality

to your Switch. For example you can install a Cascade module to enable the Switch to be stacked with other Switches. Please note that Power over Ethernet is not supported on expansion modules on the Switch 4400 PWR (3C17205). Contact your supplier for more information.

WARNING: When an Expansion Module is not installed, ensure the blanking plate is fitted by tightening all screws with a suitable tool.

Choosing a Suitable

The Switch is suited for use on a desktop, either free standing or

Site

mounted in a standard 19-inch equipment rack. Alternatively, the Switch

 

can be mounted in a wiring closet or equipment room, as an aggregator

for other Hubs and Switches. A rack-mounting kit containing two mounting brackets is supplied with the Switch.

CAUTION: Ensure that the ventilation holes are not obstructed.

When deciding where to position the Switch, ensure that:

Cabling is located away from:

sources of electrical noise such as radios, transmitters and broadband amplifiers.

power lines and fluorescent lighting fixtures

The Switch is accessible and cables can be connected easily.

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 °C (104 °F).

If the Switch is installed in a 19-inch rack or closed assembly its local air temperature may be greater than room ambient temperature.

Rack-mounting 25

The air is as free from dust as possible.

The unit is installed in a clean, air conditioned environment.

No more than eight Switch units are placed on top of one another, if the units are free-standing.

 

The Switch is situated away from sources of conductive (electrical)

 

dust, for example laser printers.

 

The AC supply used by the Switch is separate to that used by units

 

that generate high levels of AC noise, for example air conditioning

 

units and laser printers.

 

 

Rack-mounting

The Switch 4400 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.

 

2 Locate a mounting bracket over the mounting holes on one side of the

 

Switch, as shown in Figure 6.

26 CHAPTER 2: INSTALLING THE SWITCH

Figure 6 Fitting a bracket for rack-mounting

3Insert the two screws and tighten with a suitable screwdriver.

You must use the screws supplied with the mounting brackets. Damage caused to the unit by using incorrect screws invalidates your warranty.

4Repeat steps 2 and 3 for the other side of the Switch.

5Insert the Switch into the 19-inch rack and secure with suitable screws (not provided). Ensure that ventilation holes are not obstructed.

6Connect network cabling.

7Finally place a unit information label on the unit in an easily accessible position. The unit information label shows the following:

The 3Com product name of the Switch

The 3Com 3C number of the Switch

The unique MAC address (Ethernet address) of the Switch

The serial number of the Switch

You may need this information for fault reporting purposes.

Placing Units On Top of Each Other 27

Placing Units On

If the Switch units are free-standing, up to eight units can be placed one

Top of Each Other

on top of the other. If you are mixing a variety of SuperStack® 3 Switch

 

and Hub units, the smaller units must be positioned at the top.

 

If you are placing Switch units one on top of the other, you must use the

 

self-adhesive rubber pads supplied. Apply the pads to the underside of

 

each Switch, sticking one in the marked area at each corner. Place the

 

Switch units on top of each other, ensuring that the pads of the upper

 

unit line up with the recesses of the lower unit.

 

 

Stacking Units

Switch 4400 units can be stacked together and then treated as a single

 

manageable unit with one IP address. Any combination of 24-port and

 

48-port units is allowed in a single stack.

 

The SuperStack 3 Switch 4400 SE can only be stacked with non-SE

 

Switches if it has been upgraded using the Switch 4400 SE Enhanced

 

Software Upgrade (3C17207). An upgraded Switch 4400 SE cannot be

 

stacked with a normal Switch 4400 SE.

How To Stack Units

To stack two Switch 4400 units you will need to order the SuperStack 3

 

Switch Cascade Stacking Kit (3C17227). The kit consists of two Cascade

 

Modules and a Cascade Cable. Both Switches must have an unused

 

expansion slot to allow a Cascade Module to be fitted.
