Features

The G‐Series switches include the following features:

•A base system (chassis) containing fixed interfaces in the lower left front panel

–24 RJ45 (10/100/1000Mbps,1000BASE‐TX copper) ports plus 2 combo SFP ports (G3G124‐ 24 and G3G124‐24P)

–24 SFP ports (G3G170‐24)

•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 or removed when power is supplied to the base system without impacting other modules. The IOMs available for the G3 base systems are:

–G3G‐24TX, a 24‐10/100/1000 copper port 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 per slot 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.
