3. Verify that a link exists by checking that the Link/Activity LED is on (solid green or blinking
green). If the Link/Activity LED is off, perform the following steps until it is on:
a. Verify that the cabling being used is Category 5 or better with an impedance between 85
and 111 ohms with a maximum length of 100 meters (328 feet).
b. Verify that the device at the other end of the twisted pair segment is on and properly
connected to the segment.
4. If a link is not established, contact Enterasys Networks. Refer to "Getting Help" on page xvii
for details.
Repeat all steps above until all connections have been made.

Installing an Optional SFP

Notes: Each combo SFP port on the D2G124-12 and D2G124-12P supports the installation of Mini-
GBICs for 1000Base-SX, 1000Base-LX, or 100Base-FX SFP transceivers.
Each combo SFP port in use on these units eliminates the availability of one RJ45 port. In other
words, only twelve ports can be active at any given time on components equipped with a
combination of RJ45 and SFP interfaces. When an SFP transceiver (Mini-GBIC) SFP port 11
establishes a link, RJ45 port 11 is disabled. When an SFP transceiver (Mini-GBIC) in SFP port 12
establishes a link, RJ45 port 12 is disabled.
This section describes how to install an SFP optical transceiver into combo SFP ports (11 and 12)
on the D2G124‐12 or D2G124‐12P unit
It is recommended that the options be installed first in a new installation.
