Page of 8
The 10 Gigabit Module (3C17261) provides your 3Com 
SuperStack 4 Switch 5500G-EI Family unit with one 10 
Gigabit Ethernet port. The Module conforms to the 10 
Gigabit Ethernet standard, IEEE 802.3ae, when it is fitted 
with an approved XENPAK transceiver. The Module only 
operates at 10 Gbps in full duplex mode.
The Module supports pluggable XENPAK transceivers. 
This allows you to provide 10 Gigabit/sec connectivity 
between a Switch 5500G-EI Family unit and another 
switch using the 10 Gigabit Ethernet standard.
3Com recommends that you only use XENPAK 
transceivers supplied by 3Com. If the transceiver is not a 
supported media type, it will not be recognised by the 
Switch.
Auto-negotiation is not supported in the 10 Gigabit 
Ethernet standard, IEEE 802.3ae. The flow control setting 
must be manually configured. Flow control is disabled by 
default.
LEDs
You can gather information about the status of the 
Module using the Module LEDs on the front of the
