Product Description:

This accessory kit is utilized to connect two switches together in order to configure them into an operational stack of switches. The kit supplies 2 AX742 Stacking modules and a single high-capacity stacking cable. A minimum of a single kit is required to create a stack between two switches. A group of up to 8 switches can be interconnected to form a single stack by cascading the connections between switches. It is recommended that a final connection be established between the first and the last switch to create a loop topology. This provides two 24Gbps connections per switch within the stack. Once connected the stack operates as a 48Gbps resilient, self-healing, bi-directional ring.

Product Details:

For deployment convenience, M5300 series two rear I/O bays are pre-configured for stacking mode in factory default settings, allows for zero-touch stacking as soon as back connectivity is detected.

Copper, fiber can be mixed and matched for stacking interconnect.

One AX742 Stacking Kit per M5300 switch for local, dual ring topology
AX742 is a bundle: 2 CX4 I/O modules AX744 + 1 stacking CX4 cable (1m - 3.3 ft)

Latest IEEE 802.3ak 10GBASE-CX4 specifications (infiniband)

Each I/O module half-duplex speed is 12 Gbps (24 Gbps full duplex) with 1m cable

Dual ring stacking interconnect is 48 Gbps per switch (384 Gbps per stack) when one AX742 kit per switch (two I/O modules)

Longer cable may be used (standard infiniband CX4 cable)
