Brocade Communications Systems VDX 8770-4, Hardware Installation Manual, Page: 28 / 141

∙
Console (serial) cable (provided)
∙
Ethernet cables (not provided)
∙
Either access to an FTP server or a Brocade USB device for backing up the device configuration or collecting supportsave
output data (optional)
∙
Transceivers (copper and optical) and compatible cables and direct-attach cables if needed
5. Ensure that the air intake and exhaust vents have a minimum of 5.1 cm (2 in.) of airspace.
6. Ensure that the air temperature on the air intake side is less than 40°C (104°F) during operation.
CAUTION
Do not install the device in an environment where the operating ambient temperature might exceed 40°C (104°F).
7. Ensure that the power requirements are met. Refer to the Technical Specifications" for a listing of power requirements per
component.
CAUTION
For the DC input circuit to the system (3000W supply), make sure there is a 80 amp circuit breaker, minimum
-48VDC, double pole, on the input lugs to the power supply. The input wiring for connection to the product should be
copper wire, 2 AWG, marked VW-1, and rated minimum 90o C.
The power requirements for a given device configuration depend on which modules have been installed in the device. Refer to
the
Brocade VDX 8770 Switch Technical Specifications on page 125 for information on the power consumption for the
modules that can be used in the device along with the power consumption for the cooling fans.
All numbers for the line cards assume that the card is fully populated with transceivers, including QSFPs for the 12x40 GbE and
27x40 GbE line cards. All ports are Ethernet.
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.
Environmental requirements
Ensure that the environmental requirements are met. Refer to the Brocade VDX 8770 Switch Technical Specifications on page 125.
CAUTION
Do not install the device in an environment where the operating ambient temperature might exceed 40°C (104°F).
NOTE
The 0° to 40°C (32° to 104°F) range applies to the ambient air temperature at the air intake vents on the port side of the
device.The temperature inside the chassis can reach up to 90°C (194°F) for some modules during operation. Brocade
recommends that the internal temperature not exceed 75°C (167°F). Cooling policy is based on a combination of ambient
temperature and measured temperature on the modules. Various combinations will result in an increase in fan speed to create
more cooling in the device. If a component approaches a critical temperature that will trigger a module shutdown, there will be a
WARNING message in the RASlog, followed by a CRITICAL message saying that the module will shut down in two
minutes.Use the show environment command to view temperature status.
NEBS requirements
The following table lists the installation requirements for meeting NEBS GR-1089 compliancy.
