Enterasys G3G-24SFP Quick Reference Manual

Installing the Module
Electrical Hazard: Only qualified personnel should perform
installation procedures.
Use this Quick Reference to install or replace an IOM
(Input/Output Module) into an available slot of an Enterasys
G‐Series switch. Refer to the Enterasys G‐Series Hardware
Installation Guide for the procedure to disconnect power and
remove the switch from a rack.
Handling the IOM
Caution: The IOM can be damaged by electrostatic discharge.
To prevent electrostatic damage, observe the following guidelines:
• Attach an ESD wrist strap to your wrist.
• Remove the IOM from its packaging only when ready to install.
• Do not touch IOM pins, connectors, or components.
• Hold the IOM by its edges or front panel only.
• Store or transport the IOM only in anti‐static packaging.
Tools
This installation requires a Phillips screwdriver.
Optional PoE Installation Procedure (G3G-24TX IOM only)
Note: This procedure applies only to the G3G-24TX IOM for which an
optional Power over Ethernet (PoE) module has been purchased separately
from Enterasys Networks.
If you have purchased an optional PoE module (G3G‐POE), you
can install it before installing the G3G‐24TX IOM into the G‐Series
base system chassis. You can also install it at any time by first
removing the IOM module as described in this document.
The G‐Series PoE module will be shipped in a separate package.
Unpack and install the PoE card in the IOM as follows:
1. Gently plug the PoE module into the IOM by fitting the
standoffs into the PoE board mounting holes as shown in
Figure 1. There should be a direct vertical translation of
standoffs to PoE mounting holes.

2. Using the screws shipped with the PoE module, firmly attach
the PoE module to the IOM.
IOM Installation Procedure
1. Remove the coverplate from the slot.
2. Insert the IOM in the guide rail of the slot. Gently slide the
module into the slot, as shown in Figure 2, until the IOM
engages the connector on the backplane and the module locks
into place and is flush with adjoining coverplates.
3. Tighten the two captive screws.

4. To install additional modules, remove the coverplate(s) from
the slot(s) and repeat the earlier steps. Save coverplates for
optional future use.
5. After completing all module installation, be sure to install
coverplate(s) over any unused IOM slot(s) to contain EMI
radiation and ensure proper air circulation.
Note: You must reboot the system before hot-inserted IOM modules will be
recognized. Once rebooted, module LEDs will display as described later in
this document.
IOM Removal Procedure
Caution: Do not attempt to remove an IOM module from the G-Series
switch when power is on to the switch without performing the following
procedure.
1. Disconnect any cabling from the module.
2. Loosen the module's two captive screws.
3. Press the power off button corresponding to the slot from
which you want to remove the IOM as shown in Figure
Figure 3 Chassis LEDs
1 Power Supply LEDs 3 IOM power off buttons (Slot 2, 3 and 4)
2 SYSTEM LED 4 IOM power off status LEDs (Slot 2, 3 and 4)
4. When the slot's POWER OFF status LED turns amber, gently
slide the module out of the slot.
Caution: Use caution when removing an IOM on which you have optional
PoE installed to avoid damaging the PoE module.
5. Replace the slot's coverplate to contain EMI radiation and
ensure proper air circulation.
Specifications
The G3G‐24TX and G3G‐24SFP IOMs can be installed in the
G‐Series Ethernet switch.
Interfaces
G3G-24TX
24 RJ45 100BASE‐TX ports
Two combo SFP ports
G3G-24SFP
24 SFP ports
Note: Each combo SFP port on the G3G124-24, G3G124-24P or
G3G-24TX supports the installation of Mini-GBICs for 1000Base-SX,
1000Base-LX, or 100Base-FX 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.
