Stack Trunks of 1Gbps SFP Ports 1 to 24 on x530-28GSX Switches
Unlike the other switches in the x530 Series, the x530-28GSX Switch
does not have any 1Gbps copper ports or 5Gbps multi-speed copper
ports. Instead, it has four SFP+ ports and twenty four 1Gbps SFP ports.To
build a stack of x530-28GSX Switches, you can use either the SFP+ ports
or up to eight of the 1Gbps SFP ports. For guidelines on building a trunk
with SFP+ ports, refer to “Stack Trunks of the Default 10Gbps SFP+ S1
and S2 Stacking Ports,” on page 66. Here are the guidelines to building
the trunk on x530-28GSX Switches with 1Gbps SFP ports:
 Stacks can have up to four x530-28GSX Switches.
 Trunks can have from two to eight 1Gbps SFP ports per switch.
 Switches must have the same number of trunk ports.
 Stacks can have only x530-28GSX Switches. To build stacks that
have x530-28GSX Switches and other x530 models, use SFP+
ports for the trunk instead.
 The stack will be easier to manage if you use the same 1Gbps
SFP ports as the trunk on all the switches.
 Once ports are designated as trunk ports with the STACKPORT
command, you cannot view or change their settings
The example in Figure 25
shows two stacks of three x530-28GSX
Switches with trunks of 1Gbps SFP ports. The switches are connected by
two ports each in the first example and four ports in the second example,
for greater bandwidth. The maximum number of ports per switch for the
trunk is eight.
