NEBS Compatibility
The management/asyn intra-building ports of the Rapier 48w are suitable for
connection to intra-building or unexposed wiring or cabling only. The
management/asyn intra-building ports of the Rapier 48w 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.
Switch RJ-45 Ports
Caution. Do not plug a phone jack into any RJ-45 port. Doing so could damage
the switch. Use only twisted pair cables with RJ-45 connectors.
For 10BASE-T/100BASE-TX connections, a twisted pair cable must be used.
Each pair is identified by two different colours. For example, one wire might be
red, and the other red with a white stripe. An RJ-45 connector must be fitted to
both ends of the cable.
Figure 19
illustrates the pin layout for RJ-45 connectors.
Figure 19: RJ-45 Pin layout
With 10BASE-T/100BASE-TX cables, pins 1 and 2 are used for transmitting
data, while pins 3 and 6 are used for receiving data.
Table 4
lists the RJ-45 Pin
assignments.
