3. Crimp the #2 AWG power supply wires into the power lugs.
4. Connect the power lugs to the power supply unit.
Connect the -48V wire to the negative terminal and the 0V wire to the positive terminal.
NOTE
The DC return must be isolated from the chassis ground (DC-I) when making connections to the connections to
the power supply.
5. Replace the safety cover.
6. Plug the other end of the cable into the power source.
ATTENTION
Do not connect the switch to the network until the IP addresses are configured.
Preparing to configure the Brocade VDX 8770-8
The Brocade VDX 8770-8 must be configured before it is connected to the fabric, and all of the configuration
commands must be entered through the active MM. The Brocade VDX 8770-8 configuration includes the following
parameters:
• RBridge ID, If you are going to have more than one switch in a fabric.
• IP address and gateway address for the switch
• IP addresses, host names, and gateway addresses for one or two MMs, as needed
• Host name
You also need to change passwords from their default values and set the time and date, either via NTP or manually.
In order to retain the changes made during configuration you will have to copy the running configuration file to the
startup configuration file. This will ensure that the switch reboots to your preferred configuration.
The configuration information is mirrored to the standby MM, if you have installed one, which allows the current
configuration to remain available even if the active MM fails. The configuration information for the Brocade VDX
8770-8 is stored in the CID cards and the flash memory of the MMs. The configuration can be backed up to a
workstation (uploaded) and then downloaded to the active MM if necessary.
By default, the Brocade VDX 8770-8 is in VCS™ mode. It cannot be configured in standalone mode. Without a VCS
license, the switch can be part of a two-node cluster where two switches are connected in VCS mode to form an
Ethernet fabric. To be part of a larger cluster, you must install a VCS license.
In VCS mode, the switch is part of an Ethernet fabric involving two or more VCS-enabled switches. VCS technology
embodies the concept of distributed intelligence. Distributed intelligence means that all configuration and
destination information is automatically distributed to each member switch in the fabric. Distributed intelligence has
three major characteristics:
• The fabric is self-forming. When two or more VCS-enabled switches with unique Rbridge IDs are connected to
form an Ethernet fabric, the fabric is automatically created and the switches discover the common fabric
configuration.
• The fabric is masterless. No single switch stores configuration information or controls fabric operations. Any
switch can fail or be removed without causing disruptive fabric downtime or delayed traffic.
