Are universal rails provided with rack mount appliances?


This answer differs by system Generation.  

Current Generations:  All Generation 9 and 10  Rack Mountable appliances ship with included Rail Kits for standard racks.  Alternate Rail Kits are available for Full Rack Depth Gen 9 and 10 appliances as noted in the chart below.  All optional rail systems for Generation 9 and 10 appliances can be acquired directly from Dell or Dell resellers and are not stocked by Unitrends/Kaseya.  

Desktop Models ION and ION Plus as well as 10002 do not come with or support rails

Generation 7 and 8:  

Half Rack Class: (6xx or 8002-8012)

These systems do not come with rail kits.  These appliances mount to racks using the included rack "ears" and should be stabilized on a rack shelf.  An optional traditional rail kit is available from SuperMicro and can be purchased through numerous vendors, but is not carried by Unitrends.  

Full Rack Class (1U or larger) and and MAX appliances

These come with standard depth square-hole standard rack rails.  These rail kits are compatible with universal 4 post square-hole racks of expected depths.  Alternative rail kits to conform to racks that do not meet the stated mounting requirements conveyed in the 10.0 edition of the site preparation guide may be available from SuperMicro directly for some chassis models for additional purchase from 3rd party.

If you are unable to locate suitable rails for your 3rd party rack:  You may use a certified/approved rack shelf rated for not less than the Unitrends Appliance listed weight support designed for your non-standard rack.  

Warning:  Do not stack other equipment or servers on top of a mounted Unitrends appliance, the rails are rated ONLY for the listed weight of the appliance and must not support additional equipment placed above.    

Proper server racking instructions for heat dissipation as well as easy ability to slide forward and remove covers from systems for maintenance assume each system will be racked such that there is 1u of free space above and below each system.  Placing systems directly in contact on rails above Unitrends Appliances would result in a necessity to de-rack the unit for internal service.  Systems mounted with static rails or shelves may be best with additional vertical space above as they cannot slide forward.  

For older generation appliances, see the Site preparation Guide that was shipped with your appliance release and reference the Chassis Number for your model.  If you cannot locate this guide or have an older chassis not listed here covered by an active support contract, please contact Unitrends support and we can look that information up for you.  Again, Unitrends does not directly sell alternate rail kits, you will need to contact a 3rd party reseller to acquire those components.  


Rail Kit Warranty:  Rail kits, as with other boxed accessories not contained within the chassis of the Unitrends Appliance, are not covered by any warranty from Dell services, Unitrends, or Kaseya for Generation 9/10 systems.  These items are considered free accessories and are not part of the licensed unit's terms. Out-of-box damage to individual components is covered by Dell and will usually result in entire unit replacement if there is any damage to items inside the shipping container.  If rail kits are damaged on initial receipt, customers will be expected to assist Unitrends in providing suitable evidence to the shipper in a timely fashion to file a shipping damage claim and Unitrends will replace at its option the entire server system and not components individually.  Unitrends does not stock rail kits separately from new server chassis systems and therefore cannot send replacement kits on their own.  No physical damage to rail kits is provided of any kind of warranty other than damage caused in initial product shipping confirmed within the timeframes required by the shipper to file such claims (usually 24 hours from receipt).  We strongly encourage our customers to open and inspect package contents and verify unit functions within 1 day of accepting delivery as we cannot warranty system damage outside that period.  Rail kits are fragile and care must be taken using a minimum of 2 persons to safely rack a sever unit without causing damage to the rails.  Damage incurred when attempting to assemble or install the kit is NOT covered.  Customers will be responsible for acquire replacements through authorized dell retailers or dell's sales website for any damaged kits other than damage occurring in shipping and filed within the carrier's claims period.
