4 Mgmt Port Connector The Ethernet Management port has an RJ-45 connector and is used for the
initial system startup as well as system configuration and monitoring. It
supports both half and full duplex modes, and 10M/100M or
autonegotiated communication.
Refer to Management Port on page 150 for pinout assignments.
LEDs
Link
Data
The Link LED is located in the top left corner of the port and the Data
LED is located in the top right corner.
Amber (blinking): Indicates that the Ethernet link has Rx/Tx activity
Unlit: Indicates that the Ethernet link has no activity, or is down or
disabled
Green: Indicates that there is a valid communications link
Unlit: Indicates that there is no communications link, or that the link is
operationally down or disabled or shut down
Note: The Data LED is not affected by a Lamp Test.
5 Console — The console port is a DTE port with a DB9 male connector and is used for
the initial system startup as well as system configuration and monitoring.
The console port is a Universal Asynchronous Receiver/Transmitter
(UART) port. Refer to Console Port on page 151 for pinout assignments.
Use an EIA/TIA-232 DTE console cable to connect a terminal to the
console port. The factory default baud rate is 115.2 KBaud, and can be
reconfigured for 9.6, 19.2, 38.4, or 57.6 KBaud.
6 Sync In The “In” synchronization port has a 1.0/2.3 coaxial connector that can be
used to receive an external synchronization input signal.
Out The “Out” synchronization port has a 1.0/2.3 coaxial connector that can be
used to provide an external synchronization output signal.
7 Ejector
lever
— The ejector levers help insert and remove the CSM from its card slot.
When rotated outward, the levers release the CSM connectors from the
backplane.
