AMC serial port
RJ-45

You can access the AMC CLI of the switch
module from the port. The baud rate is
115200 bps.
It can be used only by technical engineers to
upgrade the AMC firmware version.

SYS serial port
(console port)
RJ-45
1
You can access the CLI of the switch
module from the port for local management,
debugging, and maintenance.
The baud rate is 9600 bps.

A 100-GE fiber port can be used as follows:
•
A single 100-GE port.
•
Split into 4 × 25-GE ports. After it is
split, the port can only use a 100G
transceiver module or cable that
supports splitting for connection.
•
Split into 4 × 10GE ports. After it is
split, the port can only use a 40G
transceiver module or cable that
support splitting for connection.
•
For the transceiver module and cables available for the switch module and their specifications, see
"Transceiver module and cables available for the switch module."
•
For information about splitting a 100-GE fiber port and combining breakout interfaces, see "Splitting a
100-GE interface and combining breakout interfaces into a 100-GE interface."
Internal ports

25-GE port
20
•
16 of the 25-GE internal ports are used to connect the blade servers.
The 16 ports are numbered WGE 1/0/1 to WGE 1/0/16.
•
4 of the 25-GE internal ports are used to connect the pair switch module
through the midplane. The 4 ports are numbered WGE 1/0/17 to
WGE1/0/20. (The six switch modules form three module pairs with
internal ports inter-connected: Slots 1 and 4 pair, slots 2 and 5 pair, and
slots 3 and 6 pair.) As a best practice, use these ports as IRF physical
ports.
10-GE port
2
The two 10-GE internal ports are used to connect the AE module. Only
switch modules in slot 1 and 4 can connect the AE module. The two ports are
numbered XGE1/0/21 and XGE1/0/22.
