Emerson RTM-ATCA-F120-OPT manual 2.3 SFP/SFP+ Module Hot Swap

Controls, LEDs and Connectors

The SFP modules can be installed/removed both while the RTM is powered and non-powered.

The presence and also the type of SFP modules is automatically detected.

When using copper SFP modules, the speed is determined through auto-negotiation per the

802.11Ethernet specification. Optical modules do not support auto-negotiation. A 1GBit SFP module must be connected to 1 GBit fibre cables.

The following table shows which switch MIB OID each cage corresponds to.

3.2.2.3SFP/SFP+ Module Hot Swap

All SFP/SFP+ modules are hot-swappable. Changes in the network topology, including insertion or removal of SFP/SFP+ modules and the insertion or removal of optical cables, are monitored by the ATCA-F120 BBS kernel.

Due to safety concerns, the kernel will disable the optical transmitter on the SFP port (laser output) when a SFP/SFP+ module is removed. Conversely, the optical transmitter on the SFP port is enabled when the SFP/SFP+ module is inserted. These events are monitored and handled by the kernel; no action is required by operator.

When the kernel detects a discontinuity in the signal path that allows light to escape, e.g. a physical break in the optical fiber or an unplugged connector or when an SFP/SFP+ has been inserted, but the optical cable is missing, signals may be reduced to safer levels without losing integrity. Periodic heartbeat messages are transmitted until a connection has been established. Once established, all channels begin operating normal levels.
