Sfp+ And Qsfp Optics Installation; Sfp+ And Qsfp Optics Removal; Port Connectivity - Dell S6100 Installation Manual

WARNING: To prevent electrical shock, ensure that the S6100–ON is grounded properly. If you ground your equipment
incorrectly, excessive emissions may result. To ensure that the power cables meet your local electrical requirements, use a
qualified electrician.
NOTE: The Utility panel consists of two slots, PSU1 and PSU2. Insert PSUs in both slots.
NOTE: If you remove and re-insert a module in the same slot, the system detects the module. However, if you remove a module
from a slot and insert a different module into that same slot, the system does not detect the new module.

SFP+ and QSFP optics installation

The S6100–ON has SFP+, QSFP+, and QSFP28 optical ports.
For a list of supported optics, contact your Dell representative.
CAUTION: ESD damage can occur if components are mishandled. Always wear an ESD-preventive wrist or heel ground strap
when handling the S6100–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 this action can cause eye damage.
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: When you cable the ports, be sure not to interfere with the airflow from the small vent holes above and below
the ports.

SFP+ and QSFP optics removal

Remove an SFP+, QSFP+, or QSFP28 optic by pulling the tab on the optic and sliding the optic from the port.
CAUTION: When removing optics with direct attach cables (DACs) from the port, pull the release tab firmly and steadily. If you
have difficulties pulling out the cable, gently push the optic into the port with one hand and at the same time pull the release tab
slightly upwards, towards the cable or module center, with the other hand. Do not jerk or tug repeatedly on the tab.

Port connectivity

Dell recommends you distribute port groups across all four port pipes.
The S6100-ON switch has four port pipes, also known as packet processing pipelines. Because S6100-ON is a modular switch, connectivity
between the front panel ports and the port pipes depends on the module type of the four slots. For the best buffer resource usage,
distribute the functional port groups, such as downlinks, uplinks, interchassis links, LAGs, and ECMP across all four port pipes—0, 1, 2, and
3. If that is not possible, distribute the port groups across port pipes 0 and 2 or port pipes 1 and 3.
For example, with 8 x 100G modules, create a two-port LAG using port 1/7 from port pipe 0 and port 1/4 from port pipe 2. With 16 x 40G
modules, create a four-port LAG using port 1/12 from port pipe 1, 1/14 from port pipe 0, 2/11 from port pipe 2, and 2/13 from port pipe 3.
With 4 x CXP + 4 x QSFP28 modules, create a two-port LAG using port 1/6 from port pipe 1 and port 2/7 from port pipe 2.
The following tables list the port to port pipe connectivity for the 8 x 100G modules, 16 x 40G modules, and 4 x CXP + 4 x QSFP28
modules:
