8 Installing the Hardware
Attaching the S25P to the Rack
The S25P is shipped with universal front-mounting brackets (rack ears) attached. The screws for attaching
those ears to a standard 19-inch rack are in the bag that also contains the S-Series CD-ROM.
Position the S25P chassis in the rack. Secure the chassis with two screws through each bracket and onto the
rack post.

Warning: As with all electrical devices of this type, take all necessary safety precautions to prevent injury
when installing the system. Electrostatic discharge (ESD) damage can occur if components are
mishandled. Always wear an ESD-preventive wrist or heel ground strap when handling the switch and its
components.
Warning: For fan maintenance and proper ventilation, position the switch in an equipment rack (or
cabinet) with a minimum of five inches (12.7 cm) of clearance around the side intake and exhaust vents.
Warning: The site where the switch is placed should be a dry, clean, well-ventilated, and
temperature-controlled room, away from heat sources such as hot air vents or direct sunlight, and have an
environmental temperature between 32° – 122°F (0° – 40°C).
Note: The front-mounting installation above is one of several installation options contained in the
book Installing the S25P System. Other options include rear mounting, four-post mounting, and
table-mounting.
