Slot numbering and configuration
The slot number specifies the physical location of a module in a switch or router, and the number of
available slots of each type (interface, management, or switch fabric) depends on the router. Slot
configuration is done on a slot-by-slot basis, and the configurations are stored in a persistent database
on the switch.
Slot numbering
The slot numbering on the Brocade VDX 8770 chassis is based on the module type. The slot numbers
for the line card are numbered L1 through L4 on the Brocade VDX 8770-4, and L1 through L8 on the
Brocade VDX 8770-8. The slots for the management modules are numbered M1 and M2. The slots for
the switch fabric modules are numbered S1 through S3 on the Brocade VDX 8770-4, and S1 through
S6 on the Brocade VDX 8770-8.
Slot configuration
Line cards are registered with the system by type, and the slot must be configured with the correct type
before you can install an line card in that slot. When you install a new line card, the system checks
whether or not a previous configuration is associated with the slot. The following rules apply when you
install or replace an line card:
• When you install an line card and boot it up to an online state in a slot that was never occupied or
configured, the module type information is automatically detected and saved to the database. No
special configuration is required.
• If you install an line card in a slot that was previously occupied by an line card of the same type and
the slot is configured for that same type, you can hot-swap the modules without powering off the line
cards. No slot configuration changes are required.
• If the slot was previously configured for a different type of line card, the installation fails and the
module is faulted with a "Type mismatch" error. A RASLog error message is generated. You must
power off the line card and clear the slot configuration with the no linecard command before you can
configure the slot for a new line card.
The slot configuration persists in the database even after the line card is physically removed, powered
off, or faulted since it first came online. All configuration data associated with the slot is automatically
preserved across reboot or hot-swap of the line card with the same type.
Connecting to a switch
You can connect to your switch through a console session on the serial port, or through a Telnet or
Secure Shell (SSH) connection to the management port. You can use any account login present in the
local switch database or on a configured authentication, authorization, and accounting (AAA) server for
authentication. For initial setup procedures, use the preconfigured administrative account that is part of
the default switch configuration.
The switch must be physically connected to the network. If the switch network interface is not
configured or the switch has been disconnected from the network, use a console session on the serial
port.
