Installation guide

CAUTION
Use a separate branch circuit for each power cord, which provides redundancy in case one
of the circuits fails.
• Protected by a circuit breaker in accordance with local electrical codes
• Supply circuit, line fusing, and wire size adequate to the electrical rating on the device nameplate
• Location close to the device and easily accessible
• Grounded outlets installed by a licensed electrician and compatible with the power cords
DANGER
If the installation requires a different power cord than the one supplied with the device, make
sure you use a power cord displaying the mark of the safety agency that defines the
regulations for power cords in your country. The mark is your assurance that the power cord
can be used safely with the device.
4. Plan for cable management before installing the device.
Cables can be managed in a variety of ways, such as by routing cables below the device, to either
side of the device, through cable channels on the sides of the rack, or by using patch panels.
5. Ensure that the following items are available for configuration of the device:
• Workstation with an installed terminal emulator, such as HyperTerminal
• 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
6. Ensure that the air intake and exhaust vents have a minimum of 5.1 cm (2 in.) of airspace.
7. 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).
8. 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
95 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.
