Note
EIA/TIA-232 was known as recommended standard RS-232 before its acceptance
as a standard by the EIA/TIA.
The auxiliary port is an EIA/TIA-232 plug (male) that provides a data terminal
equipment interface. The auxiliary port supports flow control and can be used to
connect a modem, a channel service unit (CSU), or other optional equipment for
Telnet management.
Ethernet Port
The GRP has one Ethernet port available, using one of the following two
connection types:
•
RJ-45 receptacle—An 8-pin media dependent interface (MDI) RJ-45
receptacle for either IEEE 802.3 10BASE T (10 Mbps) or IEEE 802.3u
100BASE TX (100 Mbps) Ethernet connections.
•
MII receptacle—A 40-pin media independent interface (MII) receptacle that
provides additional flexibility in Ethernet connections. The pinout of this
standard 40-pin receptacle is defined by the IEEE 802.3u standard.
Note
The RJ-45 and MII receptacles on the GRP represent two physical
connection options for one Ethernet interface; therefore, you can use
either the MDI RJ-45 connection or the MII connection, but not both at
the same time.
