• 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
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.
Power specifications
Power for the Brocade VDX 8770-8 can be supplied with either AC- or DC-based 3000 watt power supplies. The
Brocade VDX 8770-8 has room for up to eight power supplies.
Table 2 shows the basic power specifications for each power supply.
.
CAUTION
For the DC input circuit to the system of a Brocade VDX 8770-8 (3000W power supply), make sure there
is an 80 Amp circuit breaker, minimum -48 VDC, double pole, on the input lugs to the power supply. The
input wiring for the connection to the switch should be copper wire, 2 American Wire Guage (AWG),
marked VW-1, and rated minimum 90°C.
The power requirements for a given switch configuration depend on which modules have been installed in the
switch.
Table 3 shows the power consumption for the modules that can be used in the Brocade VDX 8770-8 switch
along with the power consumption for the cooling fans.
All numbers for the line cards assume that the card is fully populated with optical transceivers, including QSFPs for
the 12x40 GbE line cards. All ports are Ethernet.
