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 switch.

4. Plan for cable management before installing the switch.

Cables can be managed in a variety of ways, such as by routing cables below the switch, to
either side of the switch, 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 Brocade VDX 8770-8:

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 switch
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.
