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
Switch and the Port LED on the Module.
