Summary of Common Switch Features

Safety Information

Before you begin the process of installing or replacing a mini-GBIC, read the safety information in this
section.
CAUTION
Mini-GBICs can emit invisible laser radiation. Avoid direct eye exposure to beam.
Mini-GBICs are class 1 laser devices, and they operate at 3.3 V. Use only Extreme Networks-certified
mini-GBIC devices.
If you see an amber blinking mini-GBIC port status LED after you install a mini-GBIC into the
Summit24e3 or Summit48si switch, this means the mini-GBIC is not certified by Extreme Networks. To
correct this problem, install an Extreme Networks-certified mini-GBIC, available from Extreme
Networks, into the port in the switch.

Preparing to Install or Replace a Mini-GBIC

To ensure proper installation, complete the following tasks before inserting the mini-GBIC:
1 Disable the port that is needed to install or replace the mini-GBIC.
2 Inspect and clean the fiber tips, coupler, and connectors.
3 Prepare and clean an external attenuator, if needed.
4 Do not stretch the fiber.
5 Make sure the bend radius of the fiber is not less than 2 inches (5.08 cm).
In addition to the previously described tasks, Extreme Networks recommends the following when
installing or replacing mini-GBICs on an active network:
1 Use the same type of mini-GBIC at each end of the link.
2 Connect one end of the link to the Tx port. Without an attenuator, measure the total loss from the Tx
port to the other site of the link. For example, the total loss must not exceed the total optical system
budget.
After you complete these described tasks, you are ready to install or replace a mini-GBIC.

Installing and Removing a Mini-GBIC

You can add and remove mini-GBICs from your Summit24e3 or Summit48si switch without powering
off the system. Figure 1 shows the two types of mini-GBIC connectors.
