10/100/1000BASE-T
Ports
The 12 10/100/1000BASE-T ports have RJ-45 connectors and are
configured as Auto MDIX (cross-over).
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 or 100 Mbps half duplex and 10 Mbps
or 100 Mbps full duplex. It is not possible to manually configure a
1000BASE-T link as auto-negotiation is mandatory in the 1000BASE-T
standard.
1000BASE-SX Ports The 6 auto-negotiating 1000BASE-SX ports have MT-RJ connectors.
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 and the flow control setting can be manually configured.
GBIC Ports The 6 GBIC ports support fiber Gigabit Ethernet short-wave (SX),
long-wave (LX) and long-haul (LH70) GBIC transceivers in any
combination. This offers you the flexibility of using GBIC transceivers to
provide connectivity between the Switch and remote 1000 Mbps
workgroups or to create a high capacity aggregated link backbone
connection.
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 and the flow control setting can be manually configured.

Choosing a Suitable
Site
The Switch 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.
To ensure this product provides optimum performance, high speed fans
are used to provide ventilation. These fans have a high audible output.
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 temperature is not restricted around the Switch or through the
vents in the side of the Switch. 3Com recommends that you provide a
minimum of 25 mm (1 in.) clearance.
Air flow around the Switch does not exceed 40 °C (104
°
F).
