To install an optional module, follow the steps below:

Step

Task

Remove the faceplate covering the module slot on PSU side of the S55.

Remove the module from its packaging and slide the module into the slot.

Secure the captive screws on the sides of the module.

Install the SFP and SFP+ optics

The S55 has 4 SFP optical ports in the PSU side of the chassis in addition to the optional SFP+ optical

modules. To install SFP or SFP+ optics into an open port, follow the steps below:

WARNING:

Electrostatic discharge (ESD) damage can occur if components are mishandled. Always wear an ESD-

preventive wrist or heel ground strap when handling the S55 and its components.

WARNING: Follow all warning labels when working with optical fibers. Always wear eye protection when

working with optical fibers. Never look directly into the end of a terminated or unterminated fiber or connector

as it may cause eye damage.

Step

Task

Position the SFP or SFP+ so it is in the correct position. (The optic has a key that prevents it from being inserted

incorrectly.)

Insert the optic into the port until it gently snaps into place.

NOTE: For details on Dell Force10 supported optics, refer to

specifications.asp

Connect stacking ports (optional)

Rack-mount the switches or insert them into a cabinet before you make your stacking port connections.

Insert one end of the stacking cable into a stacking port, and insert the other end into a stacking port of the

adjacent switch. Hand-tighten all captive screws to ensure that the cable is secure in the connector.

Dell Force10 supports stacking connections for up to 12 S55 switches, to configure as a unified system.

CAUTION: The S55 system does not stack with other S-Series systems.

You can connect the switches while they are powered down or up. Both ring topology and cascade

topology connections are supported

When using the 2-port 12G stacking module, the stacking ports are labeled 48-49 on the PSU side.

NOTE: Use only the supported stacking cables for connecting the switches.
