You can calculate your power requirements by combining the power demands for the various modules and fan units
in your configuration. While you may use fewer ports in a given line card, it is always safer to use the power
requirement of a fully populated card.
CAUTION
For the NEBS-compliant installation of a Brocade VDX 8770-8 with AC or DC systems, use a ground wire
of at least 2 AWG. The ground wire should have an agency-approved crimped connector (provided with
the device) attached to one end, with the other end attached to building ground. The connector must be
crimped with the proper tool, allowing it to be connected to both ground screws on the enclosure. Before
crimping the ground wire into the provided ground lug, ensure that the bare copper wire has been
cleaned and antioxidant is applied to the bare wire.
Environmental requirements
DANGER
Do not install the router in an environment where the operating ambient temperature might
exceed 40°C (104°F).
Table 4 lists the environmental operating ranges for the Brocade VDX 8770-8. The requirements for non-operating
conditions are also provided for acceptable storage and transportation environments.
