Installing Mini-GBICs
Extreme Networks Consolidated "e" and "i" Series Hardware Installation Guide 373
Installing Mini-GBICs
The following types of mini-GBIC interfaces are available:
• 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
• 1000BX bidirectional mini-GBIC, which conforms to the IEEE 802.3ah standard:
— 1000-Base-BX-U, 1490 nm TX/1310 nm RX wavelength
— 1000-Base-BX-D, 1310 nm TX/1490 nm RX wavelength
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 to install or replace a mini-GBIC, read the safety information in this section.
NOTE
Compliance Information: Compliant with EN60825-1+A2:2001 for European Union; Compliant with FCC
21 CFR Chapter 1, Subpart; Class 1 Laser Product; Refer to switch or I/O module specific
documentation for further compliance information when this optic device is installed within a system.
CAUTION
Mini-GBICs can emit invisible laser radiation. Avoid direct eye exposure to the beam.
Use only Extreme-approved optic devices within Extreme switches. Optical modules provided by
Extreme Networks are compliant for use with Extreme systems.
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).
