s the race for the best AI technology heats up, manufacturers are turning to liquid immersion cooling to stabilise the servers of the future. While this technology provides far superior cooling properties compared to
traditional fans, it also brings a new set of challenges, particularly around maintenance. Server blades are packed extremely tightly in a small space and immersed in liquid coolant, which can make it difficult to remove a single blade for service. During maintenance, screws can be dropped and lost in the enclosure and hands can slip on slick metal as technicians try to lift heavy, liquid-covered hardware. These mishaps risk costly damage to server blades, and more importantly, loss of server uptime. In this AI race, the more time you spend running the better off you are, and every second counts. That is why Southco is introducing the RA Rack Attach. The RA Rack Attach replaces traditional screws that normally secure a server blade to a rack. Instead, those screws are used to attach the RA to the blade, and an integrated pawl secures the blade to the rack. This pawl retracts when a technician presses an integrated trigger in the Rack Attach handle, providing easy release from the rack, and a secure grip for the technician as they lift out the blade in one fluid motion. No more screws slowing down maintenance, and increased uptime for servers as they support the tech of the future.
While space is at a premium in these liquid cooled server racks, the RA Rack Attach barely takes up any, according to Southco. The device is only 7mm thick, but its steel construction enables it to support 50kg of weight. Technicians get a strong, ergonomic grip with

barely any space used by the Rack Attach. These features are said to “drastically decrease maintenance time and risk of damage and injury to technicians”. Implementing the Southco RA Rack Attach
means lower costs, increased uptime, and a leg up in the race to power the technology of the future.

FDB ELECTRICAL POWER PROTECTION DEVICES FOR CUSTOM PANEL BUILDING
P
ower protection panels from FDB Electrical are said to be known for their effectiveness and reliability – less so perhaps the availability of the specialist components offered by FDB. MD Gary Miles explains that these components enable electrical engineers to install their own power protection and/or earth monitoring circuits in housings of their choice to suit applications from domestic through industrial/office to MOD ready.
He pointed out that “as part of our commitment to electrical protection technologies the component range includes an online, ex-stock program of panel mounting components including RCDs, Earth Continuity Monitors and special- purpose electrical protection devices.” These comply with BS4293 and come in both AC and DC types. Components offer multi- range protection levels including pre-set and
user-adjustable types. Their solid-state circuitry provides immunity to voltage transients and DC components and associated core balance transformers are available in a range of sizes, and a panel meter is available (EFU10/M). Protective devices available from FDB include fully adjustable multi-function RCD’s, variable earth leakage relays, percentage earth fault relays together with a range of external toroidal CT’s up to 240mm diameter. Where a customer does not wish to produce the housed system themselves then FDB offer custom built panels and bespoke solutions designed and manufactured in-house to suit virtually any industrial application – they are proud to supply the UK Defence forces and support industries with this specialist protection equipment.
