Gigabit Interface Connector (GBIC) Installation Note
You can add and remove GBICs from your Extreme Networks switch without powering off the system. The two types of GBIC modules are shown in Figure 1. Figure 1: GBIC modules
Module A
Module B
EW_GBIC
GBICs are a Class 1 laser device. Use only Extreme-approved devices.
NOTE Note: Remove the SC fiber-optic connector from the GBIC prior to removing the GBIC from the I/O module.
CAUTION Caution: GBICs can emit Invisible laser radiation. Avoid direct eye exposure to beam. To remove the GBIC module labeled “Module A,” lift up on the front handle and pull the GBIC out of the slot. To remove the GBIC module labeled “Module B,” gently squeeze the sides to release it, and pull the GBIC out of the slot.
Part Number: 120020-00 Rev F

To insert a GBIC module, follow these steps: 1 Holding the GBIC by its sides, insert the GBIC into the slot on the I/O module. 2 Slide the GBIC as far back into the slot as possible, until you hear it click. 3 If the GBIC has a handle, push down on the handle to secure the GBIC in the slot.

*Extreme Networks proprietary. Connections between two Extreme Networks 1000BASE-LX interfaces can use a maximum distance of 10,000 meters.
NOTE Note: For more information on 1000BASE-SX and 1000BASE-LX link characteristics, refer to IEEE standard 802.3, 1998 Edition, Table 38-2 and Table 38-6.

Identifying ZX GBIC Rev 03 Modules To identify the type of ZX GBIC module you have, look at the label on the top of the ZX GBIC module. If you see one of the following on the label, you have a ZX GBIC Rev 03 module: • DVA-1203 sticker near the top of the label that covers the Extreme Networks logo • ZX GBIC (1203) wording near the top of the label • ZX GBIC Rev 03 wording near the center of the label Table 6: LX70 GBIC Specifications Parameter

Long Range GBIC System Budgets Measure cable plant losses with a 1550 nm light source and verify this to be within budget. When calculating the maximum distance attainable using optical cable with a specified loss per kilometer (for example 0.25 dB/km), Extreme Networks recommends that 3 dB of the total budget be reserved for losses induced by cable splices, connectors, and operating margin. Figure 2 shows the total optical system budget between long range GBICs.
