A network communication device is disclosed. The network communication device includes a circuit board, a network connector, a network chip and a plurality of network magnetic assemblies. The network connector, the network chip and the network magnetic assemblies are disposed on the circuit board. The network magnetic assemblies are electrically connected with the network connector and the network chip, respectively. Each of the network magnetic assemblies includes an Ethernet transformer and at least one inductor. The Ethernet transformer is electrically connected in series with the inductor via a conductive trace of the circuit board. The spaced distance or a path length of the conductive trace between the Ethernet transformer and the inductor of the at least one network magnetic assembly is less than a first specific length.

A protective cover includes a base, a first member, and a second member. The base includes a sliding portion in an axis direction of the base. The first member includes a first sliding slot and a first fixing portion. The first fixing portion is fixed on a casing of an electronic device. The first sliding slot cooperates with the sliding portion to make the first member slide on the base in the axis direction between a position the first member overlapping the base and a position the first member being stretched out from the base, so as to adjust a length of the protecting cover. The second member is disposed on the base and includes a second fixing portion. The second fixing portion is used for being fixed on the casing.

An arc-resistant switchgear enclosure has a vent opening and a vent flap. Normally the vent flap is open to allow air to circulate through the enclosure. However, in the event of an arc fault explosion in the enclosure, the vent flap is forced to close by the explosion. As the vent flap closes, a flexible latch member moves along a keeper and prevents the vent flap from reopening. In some embodiments, the latch member contacts the keeper and props the vent flap open for normal operation.

A server enclosure includes an enclosure body, a connecting member, and a loading member. The enclosure body includes a bottom wall and two sidewalls extending from the bottom wall. The two sidewalls is substantially parallel to each other. The connecting member includes a top panel and two resisting panels extending from the top panel. The top panel is substantially parallel to the bottom wall. The loading member includes a bottom panel substantially parallel to the top panel and two connecting panels extending from the bottom panel. A cross section of the loading member, taken along a plane parallel to the sidewall, is U-shaped. The bottom panel is secured on the top panel. The loading member is secured between the two sidewalls.
