Installing Mini-Gbics; Safety Information; Preparing To Install Or Replace A Mini-Gbic - Extreme Networks Summit 300-24 Hardware Installation Manual

Installing GBICs and Mini-GBICs
CAUTION
GBICs can emit invisible laser radiation. Avoid direct eye exposure to the beam.
To remove a GBIC similar to the one labeled "Module A" in Figure 179, rotate the front handle up and
pull the GBIC out of the slot.
To remove a GBIC similar to one labeled "Module B" or "Module C" in Figure 179, squeeze the side
tabs to release the GBIC, and pull the GBIC out of the slot.

Installing Mini-GBICs

There are three types of mini-GBIC interfaces:
• SX mini-GBIC, which conforms to the 1000BASE-SX standard
• LX mini-GBIC, which conforms to the 1000BASE-LX standard
• ZX mini-GBIC, which conforms to the IEEE 802.3z standard
Use only Extreme Networks-certified mini-GBICs, available from Extreme Networks, in the mini-GBIC
port in the switch or module.

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 the beam.
Mini-GBICs are Class 1 laser devices, and they operate at 3.3 V. Use only Extreme Networks-certified
mini-GBIC devices.

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.
In addition to these tasks, Extreme Networks recommends the following when installing or replacing
mini-GBICs on an active network:
• Use the same type of mini-GBIC at each end of the link.
• 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. The total loss must not exceed the total optical system budget.
• When you handle fiber optic cable, do not stretch the fiber.
• Make sure the bend radius of the fiber is not less than 2 inches (5.08 cm).
