SFP and SFP+ Sockets
The PPM front panel provides ports for high-bandwidth 1 Gb and 10 Gb Ethernet I/O
transceivers. The ports are implemented as SFP and SFP+ (Small Form-Factor Pluggable)
transceiver sockets, providing configurations for the number and type of Ethernet ports.
Each SFP or SFP+ module mates with a connector mounted to the PCB inside an SFP+ cage.
The connector and cage combination provides the connection interface for the SFP or SFP+
modules. The modules provide access to the Fabric switch I/O on the PPM. Each Fabric SFP+
is connected to the Fabric switch using the 10 Gb SFI interface.
Important:
Shielded cables are required for connections to the Ethernet SFP/SFP+ ports.
Reset Button
A reset button is provided on the front panel for resetting the PPM payload, which includes the
Octeon processors, the LMP, the Ethernet switch, and associated peripherals. The switch is a
recessed button labeled RESET.

Network link
and activity
status
Green or
Amber
Controlled by the Fabric switch with these possible states:
Green: Link operating at maximum speed
Amber: Link operating at a speed slower than the
fastest possible
Off: Link failure
Blink: SFP transceiver link is active. Blink rate is
proportional to activity rate
Note:
This applies to SFP positions only. SFP+ positions
do not blink.
SFP0 –
SFP3
Network
port status
Green or
Amber
Controlled by the Fabric switch with these possible states:
Green: Port is enabled
Amber: Port is in standby mode
Off: Port is disabled
Blink: SFP error has occurred (SFP fault, or wrong
type of transceiver is installed)
a. The user application can select the LED color using the Set FRU LED State IPMI command.
b. The user application can control the LED color and illumination using the Set FRU LED State IPMI
command.
