Comm Port
The Comm Port (also referred to as the Console/Comm Port) allows you to access
the console interface (CI) screens and customize your network using the supplied
menus and screens (see Chapter 3, “Using the Console Interface”).
The Console/Comm Port is a DB-9, RS-2 32-D male serial port connector. You can
use this connector to connect a management station or console/terminal to the
switch by using a straight-through DB-9 to DB-9 standard serial port cable (see
“Console/Comm Port” on page 2-10).
BayStack 450 10/100/1000 Series Switches
Note:
The Console/Comm Port is configured as a data communications
equipment (DCE) connector. Ensure that your RS-232 cable pinouts are
configured for DCE connections (see “DB-9 (RS-232-D) Console/ Comm Port
Connector” on page E-5).
The console port default settings are: 9600 baud with eight data bits, one stop bit,
and no parity as the communications format, with flow control set to disabled.
Uplink/Expansion Slot
The Uplink/Expansion slot allows you to attach optional media dependent
adapters (MDAs) that support a range of media types (see Appendix C, “Media
Dependent Adapters” f or more information about MDA types available from
Nortel Networks).
Port Connectors
10BASE-T/1 00BASE-TX Ports
The BayStack 450-24T switch and the BayStack 450-12T switch use
10BASE-T/100BASE-TX RJ-45 (8-pin modular) port connectors.
Note:
The RJ-45 port connectors on BayStack 450 switches manufactured
prior to December 1998 are numbered 1 to 12 and 13 to 24, in succession fr om
left to right. Later units use port conn ectors t hat ar e conf igure d with o ne or tw o
dual, six-port groups, numbered 1 to 12 and 13 to 24. The top rows are odd
numbered and the bottom rows are even numbered (see Figure 1-2
page 1-2
). Port-specific examples in this guide show the appropriate port
connections when required; other examples apply to both versions.

Using the BayStack 450 10/100/1000 Series Switch
The 10BASE-T/100BASE-TX port connectors are configured as M DI-X
(media-dependen t interface- crossov er). These ports conne ct ove r straight cables to
the network interface controller (NIC) card in a node or server, similar to a
conventional Ethernet repeater hub. If you are connecting to an Ethernet hub or
Ethernet switch, you need a crossover cable unless an MDI connection exists on
the associated port of the attached device (see “MDI and MDI-X Devices” on
page E-2).
The BayStack 450-24T switch and the BayStack 450-12T switch use autosensing
ports that are designed to operate at 10 Mb/s or at 100 Mb/s, depending on the
connecting de vice. Th ese ports support t he IEEE 802.3u a utone gotiati on standar d,
which means that when a port is co nnected t o anoth er de vice t hat a lso suppor ts 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 (see “Connecting the 10BASE-T/100BASE-TX Ports” on
page 2-8).
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.
See Appendix E, “Connectors and Pin Assignments” for more information about
the RJ-45 port connectors.
100BASE-FX MT-RJ Ports
The BayStack 450-12F switch uses longwave 1300 nanometer (nm) MT-RJ port
connectors to atta ch devices over 62.5/125 or 50/125 micron multimode fiber
optic cable.
The BayStack 450-12F switch conforms to the IEEE 802.3u 100BASE-FX
standard and can be used for fiber-based 100 Mb/s connections (2 km/6562 ft
maximum distance) to other compatible Fast Ethernet devices. Single-mode fiber
cable is not supported.
