Page 30: Site Requirements
Chapter 2 Preparing for Installation Site Requirements Voltages that present a shock hazard may exist on Power over Ethernet (PoE) circuits if Warning interconnections are made using uninsulated exposed metal contacts, conductors, or terminals. Avoid using such interconnection methods, unless the exposed metal parts are located within a restricted access location and users and service people who are authorized within the restricted access location are made aware of the hazard.
Page 31: Temperature
Chapter 2 Preparing for Installation Site Requirements – Install heavier equipment in the lower half of the rack to maintain a low center of gravity and prevent the rack from becoming top-heavy and tipping over. – Install the stabilizers before mounting or servicing the switch in the rack (if the rack is provided with stabilizing devices).
Page 32: Air Flow
Chapter 2 Preparing for Installation Site Requirements • Allow a 2-hour warm-up period to bring the chassis up to normal operating temperature before turning it on for chassis that have been exposed to abnormally cold temperatures. Failure to observe these guidelines can damage internal chassis components. The Catalyst 4948E and the Catalyst 4948E-F switches are equipped with internal air temperature Note sensors that are triggered at 104°F (40°C) generating a minor alarm and at 131°F (55°C) generating a major...
Page 33: Humidity
Chapter 2 Preparing for Installation Site Requirements • Plan for future growth. Your Catalyst 4948E or Catalyst 4948E-F switches currently installed in an enclosed or partially enclosed rack might meet ambient air temperature and air flow requirements now. However, if you add more chassis or other equipment to the rack, the additional heat generated might cause the ambient air temperature within the rack to exceed 104°F (40°C) and can cause minor alarms.
Page 34: Corrosion
Chapter 2 Preparing for Installation Site Requirements Corrosion Corrosion of system connectors is a gradual process that can eventually lead to intermittent failures of electrical circuits. The oil from a person’s fingers or prolonged exposure to high temperature or humidity can corrode the gold-plated edge connectors and pin connectors on various components in the system.
Page 35: Shock And Vibration
Chapter 2 Preparing for Installation Power Source Interruptions If the wires exceed the recommended distances, or if wires pass between buildings, give special consideration to the effect of a lightning strike in your vicinity. The electromagnetic pulse caused by lightning or other high-energy phenomena can easily couple enough energy into unshielded conductors to destroy electronic devices.
Page 36 Chapter 2 Preparing for Installation System Grounding Proper grounding practices ensure that the buildings and the installed equipment within them have low-impedance connections and low-voltage differentials between chassis. When you include NEBS-compliant system grounds, you reduce or prevent shock hazards, greatly reduce the chances of equipment damage due to transients, and substantially reduce the potential for data corruption.

We strongly recommend that power cabling runs and other potential noise sources be located as far away Caution as practical from LAN cabling that terminates on Cisco equipment. In situations, where this type of long parallel cable runs exist, which cannot be separated by at least 3.3 feet (1 meter), we recommend that you shield these potential noise sources.
