Switch Interfaces
This section provides pin assignments for the asynchronous console ports,
RJ-45 switch ports, and the Redundant Power Supply (RPS) connector.
If you have installed a Port Interface Card (PIC), pin assignments for these can
be found in the Port Interface Card Hardware Reference, which can be
downloaded from www.alliedtelesis.com/support/software.
NEBS Compatibility
The DC models of the Rapier 48w and 48w-B have been tested to NEBS
requirements.
The Ethernet and management/asyn intra-building ports of the Rapier 48w
and 48w-B are suitable for connection to intra-building or unexposed wiring or
cabling only. These ports must not be metallically connected to interfaces that
connect to the OSP or its wiring. These interfaces are designed for use as intra-
building interfaces only (Type 2 or Type 4 ports as described in GR-1089-CORE,
Issue 4) and require isolation from the exposed OSP cabling. The addition of
Primary Protectors is not sufficient protection in order to connect these
interfaces metallically to OSP wiring.
The management/asyn intra-building ports can only be directly connected to
equipment within the same frame, cabinet or line-up and where the equipment
is separated by a distance of 6m or less. The exception to this is when intra-
building wiring (cabling) is used for maintenance purposes only and is not
connected during normal operation.
Console Port
All Rapier switches except the Rapier 48w and 48w-B have a single
asynchronous serial RS-232 console port, labelled “RS-232 Terminal Port /
asyn0”. The Rapier 48w and 48w-B switches have two asynchronous serial
RS-232 console ports, labelled “asyn0” and “asyn1”.
The RS-232 console ports are used to connect the switch to a management
device. For management purposes the switch’s software can be accessed from a
terminal, a PC running terminal emulation software, or from a remote location
via a modem connection. You can also use the RS-232 console ports to establish
a network connection from a remote site using SLIP and a modem.
The console ports have a DCE female connector (Figure 19). This allows the use
of a straight-through cable when connecting the switch to a terminal or PC.
Output from the show asyn command will, however, still have a DTE
perspective. The internal DTE pin roles are listed in Table 8.
