This guide provides a unified data plane and recommended connection for stacking switches. When switches assembled into a stack, the switches synchronize their actions so that network operation, like spanning tree protocol, VLAN, and stack port trunks, is able to span across all of their Ethernet ports.

N5860 and N8560 and NC8200 series switches can be connected to other switches and operate together as a single unit, this configuration is called "stacks", and is useful for quickly increasing the capacity of a network. Stackable switches can be added or removed from a stack as needed without affecting the overall performance of the stack. Depending on its topology, a stack can continue to transfer data even if a link or unit within the stack fails. This makes stacking an effective, flexible, and scalable solution to expand network capacity. Stacking Precautions l The stacking port does not support auto-negotiation. For example, a 10G port can only use 10G transceivers for networking, but cannot use 1G transceivers. l Physical member ports in a stack port must be the same type. l The port will not support stacking after split configuration setting. For example, the 40G port which has been split into 4x 10G port, can't be used as stacking port. l The FS software version running on a switch that you plan to add to a switch stack must either be the same as the master switch version. l The number of member switches in a stack should not exceed the recommended value. l The bend radius of optical fibers or cables must be larger than the minimum bend radius. The minimum bend radius of SFP+ cables is 25 mm; the minimum bend radius of AOC cables is 30 mm; the bend radius of optical fibers is generally greater than or equal to 40 mm. www.fs.com 2 N5860 And N8560 and NC8200 SERIES SWITCHES STACKING GUIDE N5860-48SC Switch The 10Gb L3 leaf switch N5860-48SC is ideal for small-sized data centers and cloud computing services.

FAQ Q1: What is the stack distance supported A1: The recommended stacking distance should be within 30m of the same machine room. Q2: Can I do LACP configuration after stack? A2: After stacking, operations such as LACP (link aggregation) can be carried out as usual. Stacking does not affect other functional configurations. Q3: The configuration I made before stacking is lost, how to deal with it? A3: We recommend that you clear the configurations such as VLAN configuration before stacking. And you can reconfigure on the master switch after the stack is complete. Q4: When stacking how is bandwidth calculated? A4: The formula for calculating the stack bandwidth is: Stack Bandwidth = Number of stack member ports in stack ports x Bandwidth of a single stack member port. www.fs.com 8
