Features
The G‐Series switches include the following features:
A base system (chassis) containing fixed interfaces in the lower left front panel
Input/Output Modules (IOMs)
There are three I/O slots on the front of the G‐Series switch, each of which can be populated 
with the available IOMs. IOMs can be inserted when power is supplied to the base system 
without impacting other modules.Newly‐installed IOMs will not be recognized by the system, 
however, until the switch is rebooted. For more information on removing a module, refer to 
"Removing an IOM" on page 2‐11. The IOMs available for the G3 base systems are:
1-2 Introduction

G3G124-24 Switch (rear view) with 1200 and 400-watt power supplies installed

24 RJ45 (10/100/1000Mbps,1000BASE‐TX copper) ports plus 2 combo SFP ports (G3G124‐
24 and G3G124‐24P)
24 SFP ports (G3G170‐24)
G3G‐24TX, a 24‐port 1000BASE‐TX (RJ45) and 2 combo port SFP module
G3G‐24SFP, a 24‐port SFP module
G3K‐2XFP, a 2‐port XFP module
G3K‐4XFP, a 4‐port XFP module
Notes: Each combo SFP port on the G3G124-24, G3G124-24P or G3G-24TX supports the
installation of Mini-GBICs for 1000Base-SX, 1000Base-LX, 100Base-FX or 1000Base-T copper
SFP transceivers.
Each combo SFP port in use on these 10/100/1000 base systems or the G3G-24TX module
eliminates the availability of one RJ45 port. In other words, only 24 ports can be active at any given
time on components equipped with a combination of RJ45 and SFP interfaces. When an SFP
transceiver (Mini-GBIC) SFP port 23 establishes a link, RJ45 port 23 is disabled. When an SFP
transceiver (Mini-GBIC) in SFP port 24 establishes a link, RJ45 port 24 is disabled.
