2 Installation and safety considerations Electrical considerations To install and operate the switch successfully, ensure the following: • The primary outlet is correctly wired, protected by a circuit breaker, and grounded in accordance with local electrical codes. • The supply circuit, line fusing, and wire size are adequate, as specified by the electrical rating on the switch nameplate. • The power supply standards provided in Table 8, "Power Supply Specifications" are met. 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 non-port side, which contains the air intake vents, facing the cool-air aisle. • All equipment in the rack should force air in the same direction to avoid intake of exhaust air. • 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 to the air intake vents on the non-port side of the switch. • The ambient air temperature does not exceed 40 C (104 F) while the switch is operating. Cabinet considerations For successful installation and operation of the switch in a cabinet, ensure the following cabinet requirements are met: • The cabinet must be a standard EIA cabinet. • A cabinet space that is one rack unit (1U) high; 4.45 cm (1.75 inches) high and 48.3 cm (19 inches) wide. • The equipment in the cabinet is grounded through a reliable branch circuit connection and maintain 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 multicabinet assembly. • The additional weight of the switch does not exceed the cabinet's weight limits or unbalance the cabinet in any way. • The cabinet is secured to ensure stability in case of unexpected movement, such as an earthquake. 6 PowerConnect B-8000 Hardware Reference Manual 53-1001788-01

Installation and safety considerations
2
Electrical considerations
To install and operate the switch successfully, ensure the following:
•
The primary outlet is correctly wired, protected by a circuit breaker, and grounded in
accordance with local electrical codes.
•
The supply circuit, line fusing, and wire size are adequate, as specified by the electrical
rating on the switch nameplate.
•
The power supply standards provided in
Table 8
,
“Power Supply Specifications”
are met.
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 non-port side,
which contains the air intake vents, facing the cool-air aisle.
•
All equipment in the rack should force air in the same direction to avoid intake of exhaust
air.
•
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 to the air intake vents on
the non-port side of the switch.
•
The ambient air temperature does not exceed 40
C (104
F) while the switch is operating.
Cabinet considerations
For successful installation and operation of the switch in a cabinet, ensure the following cabinet
requirements are met:
•
The cabinet must be a standard EIA cabinet.
•
A cabinet space that is one rack unit (1U) high; 4.45 cm (1.75 inches) high and 48.3 cm
(19 inches) wide.
•
The equipment in the cabinet is grounded through a reliable branch circuit connection and
maintain 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 multicabinet assembly.
•
The additional weight of the switch does not exceed the cabinet’s weight limits or
unbalance the cabinet in any way.
•
The cabinet is secured to ensure stability in case of unexpected movement, such as an
earthquake.
