Computing device expansion modules and control of their operation based on temperature are disclosed. According to an aspect, an expansion module includes an interface configured to operably connect to a computing device including a service manager. Further, the expansion module includes a controller configured to determine whether communication with the service manager of the computing device is enabled or not enabled. The controller is also configured to set a first temperature level at which operation of the expansion module is reduced in response to determining that communication with the service manager is enabled. Further, the controller is configured to set a second temperature level at which operation of the expansion module is reduced in response to determining that communication with the service manager is not enabled. The second temperature level is lower than the first temperature level.

A network communications component may be configured to self-lock at a signaled transmission rate. The network communications component may receive a first transmission rate signal indicating a first transmission rate. It may be determined that a transmission rate for the network communications component is unset on the network communications component. Determining that the transmission rate for the network communications component is unset may include accessing an entry for the transmission rate in a vital product data stored on the network communications component. The transmission rate for the network communications component may be set by storing an indication of the received first transmission rate in a memory location on the network communications component. Data transmission by the network communications component may be limited, in accordance with the stored indication of the first transmission rate, to not exceed the set transmission rate.

Wake on local area network (LAN) functionality is provided in a multi-root environment. An I/O device, which is share by a plurality of physical hosts, receives the MAC address contained in the wake up packet, then prepares and sends an appropriate wake signal to the targeted host. In one embodiment, the shared I/O device sends an out-of-band wake up signal to each of the physical host computers, wherein the wake up signal is a serial bit stream encoded with the MAC address so that only the physical host having a MAC address matching the MAC address in the wake up signal will be turned on. In another embodiment, the shared I/O device sends a binary ON/OFF signal directly to the targeted physical host computer over a signal line associated with the MAC address.
