Cisco ASR 9901 Hardware Installation Guide

Due to the orientation of the QSFP28 ports (20 and 21), you might not be able to disconnect fiber optic cables
while the QSFP28 transceiver module is installed in the port. To disconnect fiber optic cables from the QSFP28
ports, we recommend that you first remove the QSFP28 transceiver module from the port, then remove the
cable.

This section describes the fixed ports and modular port adapters on the Cisco ASR 9001 Router.
Fixed 4x10-Gigabit Ethernet Ports
The Cisco ASR 9001 Router has four integrated 10 GE small form-factor pluggable (SFP+) ports that operate
at a rate of 10 Gbps.
Each fixed SFP+ port has an adjacent Link LED visible on the front panel. The Link LED indicates the status
of the associated SFP+ port.
In Cisco ASR 9001-S Router, two 10 GE fixed SFP+ ports (SFP+2 and SFP+3) are disabled by default, and
can be enabled by a license upgrade.
