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
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
AX742 is a bundle: 2 CX4 I/O modules AX744 + 1 stacking CX4 cable (1m - 3.3 ft)
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)
Ordering Part Number (Worldwide): AX742
