Unstacking Servers Unstacking Servers If internal access (for maintenance or component removal and replacement, etc.) is required to a stacked server (with the possible exception of the top server), the stack must be unstrapped and the servers unstacked to remove the cover of the unit for which internal access is required (target server). NOTE HP will not support the stacking of any other A-Class server. CAUTION In order to remain within weight limitations and to prevent tipping, do not stack servers more than six high. Each server weighs approximately 23 kg (50 lbs). DO NOT lift more than one server at a time. Always use the strap when stacking servers, regardless of the number. Hewlett-Packard will not support or warrant servers that are damaged as a result of being improperly strapped or stacked more than six servers high. Follow the steps listed below: Step 1. Pull the flat end of the strap out of the loop end and pull the Velcro® pieces apart. WARNING DO NOT attempt to lift the server by the front bezel. The plastic bezel is attached by pressing it onto four ball-tipped posts located on the front of the server cover and pulls off with very little pressure. The bezel WILL NOT support the 23 kg (50 lb) weight of the server. Failure to observe this precaution will cause damage to the server and may cause personal injury. Step 2. Carefully remove the servers in the stack, one at a time, until the target server is reached. TIP At this point, a decision to remove the target server or leave it in place to work on it can be made. Removing the target server will allow you to restack the remaining servers and continue using them while the target server is being repaired. Chapter 109
