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.
The 10BASE-T/100BASE-TX/1000BASE-T ports have RJ-45 connectors and
are configured as Auto MDIX (cross-over).

Switch 5500 Family — Front View Detail 19
The default state for these ports is auto-negotiation enabled, where the
speed, duplex and flow control modes of a link are automatically
detected to provide the highest available bandwidth with the link partner.
Alternatively, auto-negotiation can be disabled. These ports can be
manually configured to 10 Mbps half duplex, 100 Mbps half duplex,
10 Mbps full duplex or 100 Mbps full duplex. It is not possible to
manually configure a 1000 Mbps link as auto-negotiation is mandatory in
the 1000 Mbps standard. If auto-negotiation is disabled, Auto MDIX
cannot function and the ports are fixed as MDIX (cross-over) mode.
If auto-negotiation is disabled on a 1000 Mbps port, the speed will drop
to the highest available speed. By default this is 100 Mbps.
1000BASE-X SFP Ports The 1000BASE-X SFP (Small Form Factor Pluggable) ports support fiber
Gigabit Ethernet short-wave (SX), long-wave (LX), long-haul (LH70) and
copper (T) SFP Transceivers in any combination. This offers you the
flexibility of using SFP transceivers to provide connectivity between the
Switch and remote 1000 Mbps workgroups or to create a high capacity
aggregated link backbone connection.

Console Port The console port allows you to connect a terminal and perform remote or
The default state for these ports is auto-negotiation enabled, where the
speed, duplex and flow control modes are negotiated. As the speed and
duplex modes are fixed by the media type, only the flow control is
negotiated with the link partner. Alternatively, auto-negotiation can be
disabled (except 1000BASE-T where auto-negotiation is mandatory) and
the flow control setting can be manually configured.
The Switch 5500-EI FX has 24 100BASE-X SFP ports. These are 100Mbps
ports that can use multi-mode fiber optic cables of up to 2km and
single-mode fiber optic cables of up to 10km.
Duplex and flow control must be manually configured.
The Switch 5500-EI FX supports copper transceivers on the Gigabit SFP
ports only.
local out-of-band management. As the console port on the Switch is an
RJ-45 port, you will need to connect an RJ-45 to DB9 converter cable to a
standard null modem cable in order to connect a terminal. The default
baud rate is 19,200.

Stacking Cable Ports
(Switch 5500G-EI)
To protect against internal power supply failure, you can use this socket
to connect the Switch to a -48 DC Redundant Power System.
You can use these ports to connect the following cables:
■ Stacking Cable (3C17262) — which enables you to stack together
two switches up to three rack units apart.
■ Resilient Stacking Cable (3C17263) — which enables you to stack
together two switches up to sixteen rack units apart.
You can stack together any combination of 5500G-EI 24 port and 48 port
units, up to a maximum of eight units.
For more information on how to connect a stacking cable to your Switch
units, please refer to the Installation Guide that accompanies your cable.
It is not possible to create a Fabric by interconnecting a 3Com Switch
5500 with any other 3Com device (such as a 5500G-EI) or mix Enhanced
Image (EI) Switch 5500 units with Standard Image (SI) units.

The Switch 5500 Family is suited for use in an internal wiring closet, a
network room, or telecommunications room, where it can be mounted in
a standard 19-inch equipment rack, or free-standing.
CAUTION: Ensure that the ventilation holes are not obstructed.
When deciding where to position the Switch, ensure that:
■ Cabling is located away from:
■ The Switch is accessible and cables can be connected easily.
■ sources of electrical noise such as radios, transmitters and
broadband amplifiers.
■ power lines and fluorescent lighting fixtures.
30 CHAPTER 2: INSTALLING THE SWITCH
■ Water or moisture cannot enter the case of the Switch.
■ Air flow is not restricted around the Switch or through the vents in the
■ 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.
■ The air is as free from dust as possible.
■ The Switch is situated away from sources of conductive (electrical)
■ The unit is installed in a clean, air conditioned environment.
■ The AC supply used by the Switch is separate to that used by units
side of the Switch. 3Com recommends that you provide a minimum of
25 mm (1 in.) clearance.
dust, for example laser printers.
that generate high levels of AC noise, for example air conditioning
units.
■ No more than four Switch units are placed on top of one another, if
the units are free-standing.
Rack-mounting The Switch 5500 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.
CAUTION: If you use a shelf or support ensure that it will not obstruct
the air flow through the side panels of the Switch.
Switch 5500 (non
PoE)
To rack-mount your Switch 5500 (non PoE):
1 Place the Switch the right way up on a hard flat surface, with the front
facing towards you.
2 Locate a securing bracket over the mounting holes on one side of the
front of the Switch, as shown in Figure 12
