This accessory module is built to insert into any one of the 4 high-speed module bays found on either the Pro SAFE GSM7428S or Pro SAFE GSM7352S. Once inserted, the high-speed module bay can then be utilized with standard 10GBASE-X XFP modules for fiber connectivity at 10 Gbps speeds. Specifically, this adapter module accommodates the Pro SAFE AXM75110GBASE-SR Short Reach or Pro SAFE AXM752 10GBASE-LR Long Reach XFP optics modules. The AX741 is hot-swappable at any time into the switch & provides hot-swappable installation or removal of standard 10GBASE-X XFP optics modules. Pro SAFE AX742 24 Gbps Stacking Kit 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 & 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 & the last switch to create a loop topology. This provides two 24 Gbps connections per switch within the stack. Once connected the stack operates as a 48 Gbps resilient, self-healing, bi-directional ring.
