Connectivity Quick Reference
for the HP AdvanceStack Switch 2000
100VG Connectivity
•Basic Configuration Guidelines:
The default Mode setting for the 100VG ports on the Switch 2000 and Switch-16 is
Auto Detect. When connecting these switches to other network devices, such as hubs
or other switches, the Auto Detect setting works in most cases and should be tried
before making any configuration changes. When connecting these switches to PCs and
workstations that have HP 10/100VG LAN Adapters, HP recommends setting the
Mode to Master.
Other allowable Mode settings are shown in the illustrations on the following pages
under “Port Mode”. The port Mode can be set through the Configuration menu using
the Switch 2000 console interface.
•Connections: 100VG ports on the Switch 2000 must not be connected to any 100VG
ports labeled “Uplink”. These ports are reserved for hub-to-hub connections.
Note that the illustrations show only twisted-pair connections; devices supporting
fiber-optic connections are connected similarly.

UTP Ethernet/10Base-T Connectivity
5
UTP Ethernet/10Base-T Connectivity
Ethernet connectivity includes twisted pair (UTP) cabling (below), and fiber-optic cabling (page 9).
Twisted Pair Cabling
The Ethernet module for the Switch 2000 has 10Base-T ports that operate as MDI-X ports, and a slot to install a
10Base-T transceiver that operates as an MDI port.
•MDI-X Operation: The four 10Base-T ports built into the module are designed for MDI-X operation (that is, for
connecting end nodes to the switch). Thus, if you connect any of these ports to an MDI-X port on another device,
use a “crossover” cable. But if the connection is to an MDI port, use a “straight-through” cable.
•MDI Operation: An optional 10Base-T transceiver in the transceiver slot operates in MDI mode (that is, for con-
necting hubs or other switches to the Switch 2000). In this case, use a “straight-through” cable to connect the
transceiver to an MDI-X port on another device, or a “crossover cable” to connect the transceiver to another trans-
ceiver or other MDI port on another device.
Note that if the connection from the 10Base-T transceiver is to another HP 10Base-T transceiver (requiring a cross-
over cable), the “long cable” option can be set on both transceivers, allowing the connection to be up to 200 meters.
See the transceiver documentation for more information. (For more on straight-through and crossover cables, see
appendix A, “Cables and Connectors”, in the HP AdvanceStack Switch 2000 Installation Guide.)

net module. If the connection from
the Router 650 is to a 10Base-T
transceiver in the Switch 2000
Ethernet module, use a crossover
cable instead.

Fiber Optic 10Base-FL Connectivity
The 10Base-FL module for the Switch 2000 has four ports offering half-duplex or full-duplex operation. The module
supports the following fiber cable and connector types:
• 62.5/125 µm multimode graded-index fiber cable
• ST connectors
