Uplink/Expansion Slot; Port Connectors - Nortel 2000 Using Manual

The console port default settings are: 9600 baud with 8 data bits, 1 stop bit, and no
parity as the communications format, with flow control set to enabled.

Uplink/Expansion slot

The Uplink/Expansion slot allows you to attach optional media dependent
adapters (MDAs) that support a range of media types (see Appendixes for more
information about MDA types available from Nortel Networks).

Port connectors

The Business Policy Switch uses 10BASE-T/100BASE-TX RJ-45 (8-pin
modular) port connectors.
The 10BASE-T/100BASE-TX port connectors are configured as MDI-X
(media-dependent interface-crossover). These ports connect over straight cables
to the network interface card (NIC) in a node or server, similar to a conventional
Ethernet repeater hub. If you are connecting to an Ethernet hub or Ethernet switch,
use a crossover cable unless an MDI connection exists on the associated port of
the attached device (see "Appendixes).
The Business Policy Switch uses autosensing ports designed to operate at 10 Mb/s
(megabits per second) or at 100 Mb/s, depending on the connecting device. These
ports support the IEEE 802.3u autonegotiation standard, which means that when a
port is connected to another device that also supports the IEEE 802.3u standard,
the two devices negotiate the best speed and duplex mode.
The 10BASE-T/100BASE-TX switch ports also support half- and full-duplex
mode operation (refer to Installing the Business Policy Switch 2000).
The 10BASE-T/100BASE-TX RJ-45 ports can connect to 10 Mb/s or 100 Mb/s
Ethernet segments or nodes.
Note: Use only Category 5 copper unshielded twisted pair (UTP) cable
connections when connecting 10BASE-T/100BASE-TX ports.
