RTC battery
Do not attempt to replace the real-time clock (RTC) battery. There is a danger of explosion if the battery
is incorrectly replaced or disposed of. Contact your switch supplier if the real-time clock begins to lose
time.
DANGER
Risk of explosion if battery is replaced by an incorrect type. Dispose of used batteries according
to the instructions.
Environmental considerations
For successful installation and operation of the switch, ensure that the following environmental
requirements are met:
• At a minimum, adequate cooling requires that you install the switch with the intake side, as indicated
by the airflow direction of the fan assemblies, facing the cool-air aisle.
• All equipment in the rack should force air in the same direction to avoid intake of exhaust air.
CAUTION
Ensure that the airflow direction of the power supply unit matches that of the installed fan
tray. The power supplies and fan trays are clearly labeled with either a green arrow with an
"E", or an orange arrow with an "I."
• A maximum of 102 cubic meters/hour (60 cubic feet/minute) and a minimum of 74.8 cubic meters/
hour (44 cubic feet/minute) of air flow is available for air intake.
CAUTION
Make sure the airflow around the front, sides, and back of the device is not restricted.
• Ensure temperature requirements are met.
CAUTION
Do not install the device in an environment where the operating ambient temperature might
exceed 40°C (104°F).
EIA rack installation considerations
For successful installation and operation of the switch in an EIA rack, ensure the following requirements
are met:
• The rack must be a standard EIA rack.
• A rack space that is at least one rack unit (1U) high; 4.45 cm (1.75 inches) high and 48.3 cm (19
inches) wide.
• The two rack kit options for the Brocade 6505 use rails that are slimmer than standard rails to
accommodate the slightly wider chassis. Be sure to use one of these kits. Do not use standard rails
to install the in a rack; they will not fit with the switch.
• The equipment in the rack is grounded through a reliable branch circuit connection and maintains
ground at all times. Do not rely on a secondary connection to a branch circuit, such as a power strip.
• Airflow and temperature requirements are met on an ongoing basis, particularly if the switch is
installed in a closed or multi-rack assembly.
