Installing the SFP+ and QSFP+ Optics
The S4810–ON has 48 SFP+ optical ports and four QSFP+ optical ports.
WARNING: 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.
WARNING: 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.
