DFE Series Module
Memory Upgrade Kit (DFE-256MB-UGK)
Installation Instructions
Before You Begin
Caution: Only authorized personnel should install the DFE Series Module Memory Upgrade Kit
(DFE-256MB-UGK).
These installation instructions describe how to upgrade the Dual-Inline Memory Module (DIMM)
on a DFE series module from 128 MB to 256 MB using the 256 MB SDRAM DIMM included in this
DFE-256MB-UGK kit.
Note: Access to advanced routing features, such as Protocol Independent Multicasting
(PIM) and Load Share Network Address Translation (LSNAT) currently require memory
greater than 128 MB. Please consult the Release Notes to see which additional features
require this memory upgrade.
To help eliminate any potential problems during or after installation, read and understand all of
the instructions in this document and in the release notes supplied with the DFE-256MB-UGK
upgrade kit.
If there are missing or damaged parts, or you need help installing the DIMM, contact Enterasys

Installing the DIMM
Caution: Observe all antistatic precautions when handling sensitive electronic equipment.
1. With the connector arms ➀ set in the open position, insert the DIMM ➁ between the
connector fingers ➂.
Caution: The connectors on different DFE modules may have the keys inside the connector
reversed. To prevent damaging the DIMM and main pc board, make sure that key slots ➃ are
positioned to match those in the connectors. Otherwise, the DIMM and pc board will be damaged.
2. Push the memory module into the connector until the tabs on the two connector arms pull in
towards the DIMM alignment notches ➄.
