GRP Ethernet Ports and Status LEDs

OL-11496-01
The auxiliary and console ports on the GRP are EIA/TIA-232 (also known as
RS-232) asynchronous serial ports. These ports are used to connect external
devices to monitor and manage the system.
Auxiliary port —A (male) plug that provides a data terminal equipment
•
(DTE) interface. The auxiliary port supports flow control and is often used to
connect a modem, a channel service unit (CSU), or other optional equipment
for Telnet management.
Console port—A (female) receptacle that provides a data circuit-terminating
•
equipment (DCE) interface for connecting a console terminal.
To maintain Class B EMI compliance, use shielded cables when you connect to
the auxiliary and console ports of original GRPs (Part Numbers GRP= and
GRP-B=). An updated version of the GRP-B= board (Rev. F0) does not require
shielded cables for Class B compliance.
The GRP has two types of Ethernet connections for Telnet use:
RJ-45 port—An 8-pin media-dependent interface (MDI) RJ-45 port for either
•
IEEE 802.3 10BASE-T (10 Mbps) or IEEE 802.3u 100BASE-TX (100 Mbps)
Ethernet connections.
MII connector—A 40-pin media-independent interface (MII) that provides
•
additional flexibility for Ethernet connections. The pinout of this standard
40-pin interface is defined by the IEEE 802.3u standard.
The RJ-45 and MII interfaces on the GRP represent two physical
Note
connection options for one Ethernet interface; therefore, you can use
either the RJ-45 connection or the MII connection, but not both
simultaneously.
