About the SuperStack II Switch 610
Summary of Features
The SuperStack® II system solves the problem of growth in dynamic
network environments and provides everything you need for successful
workgroup networking. Much more than a collection of stackable
components, the system comprises a complete, integrated architecture of
modular parts that are easy to install and use.
As part of this SuperStack II system, the Switch 610 meets the challenge
of modern LANs and allows you to add features and capacity as your
network expands.
The Switch has the following hardware features:
■
24 Ethernet 10BASE-T ports
■
Two Fast Ethernet auto-negotiating 10BASE-T/100BASE-TX ports
■
SuperStack II architecture:
■
Connects to Redundant Power System / Uninterruptable Power
System
■
19-inch rack or stand-alone mounting
For information about the software features of the Switch, refer to the
“SuperStack II Switch Management Guide” (DUA1695-0BAA0x).

Figure 1
Port Connections 10BASE-T Ports
The Switch has 24 10BASE-T ports configured as MDIX (cross-over). The
maximum segment length is 100m (328ft) over Category 3, 4, or 5
twisted pair cable.
Switch 610 — Front View Detail 13
Switch 610 — Front view
As these ports are configured as MDIX (cross-over), you need to use a
cross-over cable to connect to devices whose ports are MDIX-only. See
“Choosing the Correct Cables”
on
page 25
for more information.
10BASE-T/100BASE-TX Ports
The Switch has two auto-negotiating 10BASE-T/100BASE-TX ports
configured as MDIX (cross-over). These ports can be set to 10BASE-T half
duplex, 10BASE-T full duplex, 100BASE-TX half duplex, 100BASE-TX full
duplex, or they can automatically detect the speed and duplex mode of a
link and provide the appropriate connection. The maximum segment
length is 100m (328ft) over Category 5 twisted pair cable.
As these ports are configured as MDIX (cross-over), you need to use a
cross-over cable to connect to devices whose ports are MDIX-only. See
“Choosing the Correct Cables”
on
page 25
for more information.

This 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.
The Switch automatically adjusts its power setting to any supply voltage
in the range 90–240V A.C.
To protect against internal power supply failure, you can use this socket
to connect a SuperStack II Advanced Redundant Power System (RPS) to
the Switch. See “Connecting a Redundant Power System”
on page 24.
The console port allows you to connect a terminal and perform remote or
local out-of-band management. The console port uses standard null
modem cable and is set to auto-baud, 8 data bits, no parity and 1 stop
bit.
