1. An electronic device configured to be mounted in a housing of a cluster, the electronic device comprising:
a rear body that houses a mother board configured to be powered by the cluster;
a front tray that houses an electronic board having at least one socket,
the front tray comprising a horizontal panel for receiving the electronic board and at least one fastening member for mounting at least one expansion card, each expansion card of the at least one expansion card having an edge connector and a fastening portion,
the edge connector of the each expansion card comprising pins and is configured to be plugged into a socket of the at least one socket on the electronic board,
each fastening member of the at least one fastening member comprising a latch for securing a mounting of the each expansion card, wherein the each fastening member is located at a periphery of the front tray along a lateral edge of the horizontal panel of the front tray,
the latch being slidable horizontally and comprising a spring configured to force the latch in a locking position, such that locking of the latch in the locking position is automatic;
wherein
the electronic board is connected to the mother board by at least one flexible cable,
the front tray is mounted slidable relatively from the rear body between a close position and an open position in which the front tray is at least partially removed from the housing of the cluster while keeping the rear body into the housing of the cluster so that the each expansion card is configured to be mounted and unmounted from the electronic board without powering off the electronic device,
the fastening portion of said each expansion card and the each fastening member of the front tray are located on a same side of the electronic device,
the latch is located at the periphery of the front tray along an outer edge of the horizontal panel of the front tray, such that the latch is configured to be accessible by an operator when the front tray is in the open position, and such that the latch is configured to be slid to free the fastening portion of the each expansion card to unmount the each expansion card without powering off the electronic device,
due to the edge connector being plugged into the socket on the electronic board and upon sliding the latch, the each expansion card is configured to tilt to allow said operator to remove said each expansion card from the socket of the electronic board to unmount said each expansion card.
