LW XENPAK
To recognize the LW XENPAK module, your Extreme Networks switch must have the minimum
software release listed in Table 74.
BlackDiamond 10808 switches and BlackDiamond 12804 switches running builds earlier than ExtremeXOS
11.4.2.3 do not support jumbo-size frame for the LW XENPAK. These switches support standard-size frame only for
the LW XENPAK.
BlackDiamond 10808 switches and BlackDiamond 12804 switches running the latest version of ExtremeXOS 11.4
support jumbo-size frame for the LW XENPAK with a 5% decrease in performance, allowing for 95% of the
maximum WAN PHY traffic.
ExtremeXOS 11.5.0 or later supports the LW XENPAK at full functionality with 100% performance in the Summit
X450a and X450e series switches.
Table 75 lists specifications for the LW XENPAK module.
