1.1 Ethernet Port Overview
S3026G Ethernet Switch provides 24 10/100Base-T fixed Ethernet ports and two GBIC
uplink ports. You can select the gigabit optical module.
S3026C Ethernet Switch provides 24 10/100Base-T fixed Ethernet ports and two
extended module slots and supports 100Base-FX Multi-mode module, 100Base-FX
Single Mode module, 1000Base-SX module, 1000Base-LX module, 1000Base-T
module, 1000Base-ZX module, 1000Base-LX GL module and stack module.
10/100/1000Base-T uplink Ethernet ports.
The only difference between S3026E FM and
optical ports with the different attributes they provide: S3026E FM Ethernet Switch
provides 12 fixed 100Base-FX multi-mode Ethernet ports. S3026E FS Ethernet Switch
provides 12 fixed 100Base-FX single-mode Ethernet ports. Each of them also provides
two 6-port 100M module slots and two uplink module slots. The 6-port 100M module
slots support 6-port 10/100Base-T module, 6-port 100Base-FX single-mode module

100Base-FX multi-mode module, 100Base-FX single-mode module, 1000Base-SX
module, 1000Base-LX module, 1000Base-T electrical port module, 1000Base-ZX
module, 1000Base-LX GL module, and stack module.
S3026C-PWR Ethernet switch provides 24 fixed 10/1
and two extended module slots, which support one-port 1000Base-LX module,
one-port 1000Base-SX module, one-port 1000Base-T module, one-port gigabit long
haul/ medium haul optical interface module, one-port gigabit stack module, one-port
100Base-T single mode/multi-mode optical interface module, one-port 100Base-FX

network devices to determine the operating mode and speed. Thus the suitable
operating mode and speed can be worked out automatically and the system
configuration and management is greatly streamlined.

Chapter 2 Link Aggregation Configuration
2.1 Link Aggregation Overview
The link aggregation means aggregating several ports together to implement the
outgoing/incoming payload balance among the member ports and enhance the
connection reliability.
An S3026C/S3026G/S3026T/S3026C-PWR Ethernet Switch supports at most six
aggregated groups, with each group containing a maximum of eight fixed ports or two
extended/uplink ports. The group can start from any port, as long as the ports in it are
consecutive.
An S3026E FM/S3026E FS Ethernet Switch supports at most six aggregated groups,
with each group containing a maximum of eight ports. The ports of one group located in
the same slot must be consecutive. If two slots are involved, the slot numbers should
also be consecutive and the first port in the second slot must be added to the group
first.
In a link aggregation group, the port with the smallest number serves as the master port,
and the others serve as member ports. In one link aggregation group, the link type of
the master port and the member ports must be identical. That is, the master port and
the member ports should be in Trunk mode together, or be in Access mode together.
