User's Manual

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 on open or closed, individually. Each input can be provisioned to generate minor, major, or
critical alarms.
