Q
What is a Cisco GBIC Module?
A
A Cisco GBIC (Gigabit Interface Converter) Module is a hot-swappable transceiver that converts electrical signals into optical signals for gigabit Ethernet fiber connections on Cisco network devices.
Q
How do I install a Cisco GBIC Module?
A
To install a Cisco GBIC Module, insert the module into an available GBIC slot on the powered device until it clicks, then verify its operational status with the 'show interface transceiver' command.
Q
Which Cisco devices are compatible with GBIC Modules?
A
Cisco GBIC Modules are compatible with Catalyst switches (1900, 2900, 3500, 4500, 6500 series) and Cisco 2800, 2900, and 3800 series routers that support gigabit fiber uplinks.
Q
What is the maximum transmission distance of a Cisco GBIC Module?
A
Depending on the model and fiber type, Cisco GBIC Modules support distances from 220 meters (multimode) up to 80 kilometers (single-mode).
Q
Can Cisco GBIC Modules support different fiber types?
A
Yes, Cisco GBIC Modules are available for both single-mode fiber (up to 80 km) and multimode fiber (up to 220 m), with each model optimized for specific distance and bandwidth requirements.
Q
How do I troubleshoot a Cisco GBIC Module?
A
To troubleshoot, run 'show interface transceiver' in the CLI, inspect fiber cables for damage, confirm correct fiber type, and ensure your device IOS or NX-OS is up to date.
Q
What is the difference between Cisco GBIC and SFP modules?
A
Cisco GBIC modules have a larger form factor and support 1 Gbps, while SFP modules are smaller, consume less power, and are available in both 1 Gbps and 10 Gbps (SFP+) variants.
Q
How do I view the serial number of a Cisco GBIC Module?
A
Use the 'show inventory' or 'show module' command in the Cisco CLI to display the part number and serial number of installed GBIC Modules.
Q
What are the key benefits of using Cisco GBIC Modules?
A
Key benefits include hot-swappability, broad Cisco device compatibility, flexible fiber distance options, and reliable 1 Gbps gigabit Ethernet performance.
Q
Are Cisco GBIC Modules hot-swappable?
A
Yes, Cisco GBIC Modules support hot-swapping, allowing insertion or removal without powering down the network device and minimizing operational downtime.
Q
Do Cisco GBIC Modules require firmware updates?
A
Cisco GBIC Modules do not have standalone firmware; module compatibility and performance are managed through the host device’s IOS or NX-OS software version.
Q
What is the typical lifespan of a Cisco GBIC Module?
A
Cisco GBIC Modules typically last 5 to 7 years under normal operating conditions, with proper handling, temperature control, and compliance with Cisco specifications.
Q
How do I choose the right Cisco GBIC Module for my network?
A
Select a Cisco GBIC Module based on required data rate, fiber type (single-mode vs. multimode), desired transmission distance, and verified compatibility with your Cisco device model.
Q
Can Cisco GBIC Modules work in mixed-vendor environments?
A
Cisco GBIC Modules are certified for Cisco hardware; interoperability with third-party devices can vary, so always confirm cross-vendor compatibility before deployment.
Q
How much do Cisco GBIC Modules typically cost?
A
Prices vary by model and reseller, generally ranging from $200 to $800 USD per module, depending on fiber type and maximum transmission distance.
Q
What warranty does Cisco offer for GBIC Modules?
A
Cisco provides a limited lifetime warranty for genuine Cisco GBIC Modules, covering manufacturing defects and offering replacement support under its hardware warranty policy.
Q
Where can I purchase authentic Cisco GBIC Modules?
A
Authentic Cisco GBIC Modules are available through Cisco’s official online store, authorized Cisco partners, and certified resellers to ensure full warranty and compatibility.
