Modular Line Cards; 20-Port Gigabit Ethernet Modular Port Adapter - Cisco ASR 9001-S Overview And Reference Manual

Modular Line Cards

Modular Line Cards
The modular line card is available in two network processing unit (80-gb throughput) and in four
network processing unit (160-gb throughput) versions. Each version is available in either a Service Edge
Optimized (-SE) or Packet Transport Optimized (-TR) version. Both versions are functionally
equivalent, but vary in configuration scale and buffer capacity.

The MPA has Active/Link (A/L) LEDs visible on the front panel. Each A/L LED shows the status of both
the port and the link. A green A/L LED means the state is on, the port is enabled, and the link is up. An
amber A/L LED means the state is on, the port is enabled, and the link is down. An A/L LED that is off
means the state is off, the port is not enabled, and the link is down.
The modular line card provides two bays that support the following MPAs:

20-port Gigabit Ethernet Modular Port Adapter

The 20-port Gigabit Ethernet MPA provides 10 double-stacked SFP (20 total) cages that support either
fiber-optic or copper Gigabit Ethernet transceivers. It also supports copper SFP modules with
10/100-1000 Mbps speed.
Each SFP cage on the Gigabit Ethernet MPA has an adjacent A/L LED visible on the front panel. The
A/L LED indicates the status of the associated SFP port.
