BlackDiamond BDXA-40G24X I/O Module

The BDXA-40G24X I/O module (Figure 5) has 24 unpopulated QSFP+-based 40-gigabit Ethernet ports.

Each installed QSFP+ optical module can operate as a single 40-gigabit port or as four 10-gigabit ports.

In 40G port mode, the module provides 24 ports; if all ports are operating in 10G mode, the module

provides 96 ports.

When the ports are operating in 40-Gbps mode, the port numbers increment by 4. For example, the first

four ports in the top row would be numbered (from left to right) 1, 5, 9, and 13. Other port numbers are

displayed in ExtremeXOS as “not available.” When a port is configured to operate in 10-Gbps mode, all

four port numbers associated with that physical port are displayed as being available. The default mode

for the ports is 40-Gbps operation. To configure a port for 10-Gbps operation, use the

configure ports

partition

command.

Figure 5: BDXA-40G24X I/O Module

In the default configuration for the BDXA-40G24X module, all ports:

● Are added to the default VLAN as untagged.

● Inherit the properties of the default VLAN (for example, protocol type and VLAN ID).

The BDXA-40G24X module has the following LEDs:

● Module status (STAT)

● Module diagnostics (DIAG)

● Port status

When a port is operating in 40-Gbps mode, the farthest left LED below that port lights blue to indicate

the 40-Gbps operation. When a port is operating in 10-Gbps mode, each LED for an active channel from

the port lights green.

For information about the LEDs and their activity on the BDXA-40G24X modules, see “I/O Module

LEDs” on page 24. For information about the QSFP+ modules, see the Extreme Networks Pluggable

Interface Modules Installation Guide.

NOTE

The BDXA-40G24X module requires BDX-FM20T fabric modules in order to function.
