20 Extreme Networks Consolidated "i" Series Hardware Installation Guide
Summary of Common Switch Features
The ZX mini-GBIC is compatible with and interoperates with long range GBICs. For more information
about the budget requirements and minimum attenutation requirements of long range GBICs, see “Long
Range GBIC System Budgets” on page 26.
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
Summit48si switch, BlackDiamond G16X
3
module, or an Alpine GM-16X3 module, 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, mini-GBIC port.
If you install a mini-GBIC not certified by Extreme Networks into an Alpine GM-16X
3
module and
insert a cable to bring up the link, the port status LED remains “off” and an error specifying the use of a
non-Extreme Networks-certified mini-GBIC is sent to the syslog. To view the syslog and to determine
why the link is down, use the
show log command. To correct this problem, install an Extreme
Networks-certified mini-GBIC, available from Extreme Networks, into the mini-GBIC slot in the
module.
Preparing to Install or Replace a Mini-GBIC
To ensure proper installation, complete the following five 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.
