If the connection fails, verify that you have the correct IP address for the destination device and that the
destination device is active (powered on), and then repeat the ping command.
Installing and Removing SFP Modules
Before you remove or install an SFP or SFP+ module, read the installation information in this section and the
safety information in Laser Safety, on page 70.
Protect the line card by inserting a clean SFP/SFP+ module cage cover (A9K-SFP10G-COVER), shown in
the figure below, into the optical module cage when there is no SFP or SFP+ module installed.
Caution
Figure 47: SFP/SFP+ Module Cage Cover
Protect the SFP or SFP+ modules by inserting clean dust covers into them after the cables are removed. Be
sure to clean the optic surfaces of the fiber cables before you plug them back into the optical ports of another
module. Avoid getting dust and other contaminants into the optical ports of your SFP or SFP+ modules,
because the optics do not work correctly when obstructed with dust.
Caution
We strongly recommended that you do not install or remove the SFP or SFP+ module with fiber-optic cables
attached to it because of the potential to damage the cable, the cable connector, or the optical interfaces in the
module. Disconnect all cables before removing or installing an SFP or SFP+ module.Removing and inserting
an module can shorten its useful life, so you should not remove and insert modules any more often than is
absolutely necessary.
Caution
SFP and SFP+ modules use one of four different latching devices to install and remove the module from a
port. The four types of SFP module latching devices are described in the following sections:
