4-Port Gigabit Ethernet Layer 3 Switching Module (GBIC) Quick Start Guide
Installing the Gigabit
Ethernet Switching
Module
To install a 4-port Gigabit Ethernet Layer 3 Switching Module (GBIC):
1
To verify that you have complied with all prerequisites and are ready to
install your 4-port Gigabit Ethernet Layer 3 Switching Module (GBIC),
read “Installation Prerequisites” earlier in this guide.
2
Before you start the installation process, read “Safety Precautions” and
“Handling Precautions” earlier in this guide.
3
Select a chassis slot for your module, following the restrictions and
recommendations in “Choosing a Slot for Your Module” earlier in this
guide.
4
To expose the selected chassis slot, remove the blank faceplate that
covers the chassis slot.
Save this faceplate in case you need to cover an empty slot in the future.
Empty slots must always be covered to ensure proper airflow and cooling
in the chassis.
3Com strongly recommends that you install only one module at a time
and remove only the faceplate for the slot where you intend to install the
module. Having either a module or a blank faceplate in the slots adjacent
to your selected slot helps ensure that the module’s spring-loaded screws
align properly with the corresponding holes in the chassis.
5
Remove the module from its antistatic bag and open the two module
ejector handles so that they are nearly perpendicular to the front panel.
6
Grasp the module with two hands — one at each end of the front panel
near the ejector handles — and begin to insert the module in the slot:
■
In a 7-slot chassis, hold the module horizontally with the LEDs to the
left and then insert the module using the guides on the right and the
left of the slot.
■
In an 8-slot chassis or 16-slot chassis, hold the module vertically with
the LEDs at the top (Figure 2) and then insert the module using the
guides at the top and the bottom of the slot.
CAUTION:
Do not twist or bend the module when you insert it into the
chassis.
7
Slide the module into the chassis by pushing firmly on the two ends of
the front panel near the ejector handles.
WARNING:
Hazardous energy levels exist inside of the chassis. Do not
place hands or objects into the chassis or touch any components on an
inserted module.
