Summit Option Cards
Summit Family Switches Hardware Installation Guide
104
Before installing a Summit option card into your network:
● Read the latest installation and safety information in this chapter and the section specific to the optic
type you are installing.
● See Appendix A, “Safety Information,” for additional safety information and Appendix B, “Technical
Specifications,” for additional information regarding regulatory compliance certifications.
WARNING!
When working with laser optic modules, always take the following precautions to prevent exposure to hazardous
radiation:
● Never look at the transmit LED/laser through a magnifying device while it is powered on.
● Never look directly at a fiber port on the switch or at the ends of a fiber cable when they are powered on.
● Invisible laser radiation can occur when the connectors are open. Avoid direct eye exposure to the beam
when optic connections are unplugged.
● Never alter, modify, or change an optic device in any way other than suggested in this document.
Summit XGM-2xn Option Card
The Summit XGM-2xn option card allows you to add up to two 10-gigabit XENPAK modules to the
following switches:
● Summit X450-24x switch, running ExtremeXOS 11.2.0 (or later)
● Summit X450-24t switch, running ExtremeXOS 11.2.0 (or later)
The Summit XGM-2xn option card is compatible with the following 10-gigabit XENPAK modules:
● SR XENPAK module, operating in the 850 nm range
● LR XENPAK module, operating in the 1310 nm range
● ER XENPAK module, operating in the 1550 nm range
● ZR XENPAK module, operating in the 1550 nm range
● LX-4 XENPAK module, operating in the 1269-1355 nm range
For more information about these XENPAK modules, refer to the Extreme Networks Pluggable Interface
Modules Installation Guide.
NOTE
Standards-based CX-4 XENPAKs are also recognized by ExtremeXOS; contact your CX-4 module vendor to obtain
these.
Mixing ZR XENPAKs with Other Types
Table 21 lists the supported combinations of XENPAK types using ZR XENPAKs in a Summit X450
series switch. You can either install one ZR XENPAK and leave one slot empty or install one ZR
XENPAK and one SR XENPAK; the Summit X450 series switch does not support any other XENPAK
combinations when a ZR XENPAK module is installed. You must put the specified modules in the
specified slots, as shown in Table 21, for the switch to discover the ZR XENPAK correctly.
