Internal Interfaces
The following section provides details about the internal interface ports (within the cable bay area) supported
on Cisco ASR 901S Series Aggregation Services Router.
•
Gigabit Ethernet and Fast Ethernet Ports
—
The router supports two Gigabit Ethernet and Fast Ethernet
Cu (RJ45) ports. The ports support standard 100/1000 Base-T Ethernet features including auto-MDIX.
•
Management Ports
—
The router supports two types of management port: an RS-232 serial console and
10/100 Base-T Ethernet ports. Both ports use the RJ45 connector and are accessible via the cable gland
interface. .
◦
The
RS-232 serial console port
can operate with flow control signals clear-to-send and ready-to-send
and without flow controls. The default baud rate is 9600 and can be reconfigured to operate at a
maximum baud rate of 115200.
◦
The
10/100 Base-T Ethernet port
can auto-negotiate or force to operate at either 10 Mbps or 100
Mbps, half or full duplex. The traffic on this port is isolated from switching ports.
•
Alarm Inputs
—
The router supports four dry-contact alarm inputs. These alarm inputs can be configured
to trigger an open or closed alarm, individually. Each input can be provisioned to generate minor, major,
or critical alarms.
