Installing the SFP+ and QSFP+ Optics
The S4810–ON has 48 SFP+ optical ports and four QSFP+ optical ports.
NOTE:
ESD damage can occur if components are mishandled. Always wear an ESD-preventive wrist or heel ground strap
when handling the S4810–ON and its components.
NOTE:
When working with optical fibers, follow all warning labels and always wear eye protection. Never look directly
into the end of a terminated or unterminated fiber or connector as it may cause eye damage.
To install SFP+ or QSFP+ optics into an open port, follow these steps:
1. Position the optic so it is in the correct position. The optic has a key that prevents it from being inserted incorrectly.
2. Insert the optic into the port until it gently snaps into place.
NOTE:
Both rows of QSFP+ ports require that the 40G optics be inserted with the tabs facing up.
Remove the SFP+ and QSFP+ Optics
Remove an optic by pushing the tab on the optic and sliding the optic from the port.
When removing optics with direct attach cables (DACs) from the port, pull the release tab firmly and steadily. Prior to pulling the release
tab, you may need to gently push the optic into the port to ensure it is seated properly. Do not jerk or tug repeatedly on the tab.
Splitting QSFP+ Ports to SFP+ Ports
The S4810–ON supports splitting a single 40G QSFP+ port into four 10G ports using one of the supported breakout cables.
