SERIES SWITCHES STACKING GUIDE
Better understand the concepts and procedures to manage FS S5860, S5810,
S3910, S3410 series switches stacks
Overview
This stacking guide is intended to provide a true stacking solution for S5860, S5810, S3910, S3410 series witches. This guide provides a unified data plane and recommended connection for stacking switches. When the switches are 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.S5860

What is Stacking?
S5860 & S5810 & S3910 & S3410Switches 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
- The stacking port does not support auto-negotiation. For example, a 10G port can only use 10G transceivers for stacking, but cannot use 1G transceivers.
- Physical member ports in a stack port must be the same type.
- The port will not support stacking after the split configuration setting. For example, the 40G port which has been split into 4x 10G port, can’t be used as a stacking port.
- 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. The number of member switches in a stack should not exceed the recommended value.
- 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.

The following figure 1, 2 and 3 show the locations of ports that can be used
as stack ports on the switches, and the stacking ports could both be used as
business ports.

The following figures 4 and 5 show the appearance of the S5860 series, which
may be different from your selected model. The figures illustrate how to
connect these ports in different stack connection models. Recommended stack
connections are shown in ring topology which is more stable and reliable.

FAQ
Q1: What is the stack distance supported?****
– The recommended stacking distance should be within 30m of the same machine room.
Q2 Can I do LACP configuration after stack?****
– 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 the 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.
