Notes:  
1.    Either slimline doors or acoustical doors must be selected by the customer during the order process. 
2.    Door options determine which doors are included with your Eserver pSeries 655. See “Eserver pSeries 655 
Doors and Covers.”
 
  
Eserver pSeries 655 Doors and Covers 
Covers are an integral part of the Eserver pSeries 655 and are required for product safety and EMC 
compliance. The following rear door options are available for the Eserver pSeries 655: 
v   ″Enhanced Acoustical″  Cover Option 
 This feature provides a low-noise option for customers or sites with stringent acoustical requirements 
and where a minimal system footprint is not critical. The Acoustical cover option consists of a special 
front and rear doors which are approximately 250 mm (10 in.) deep and contain acoustical treatment 
that lowers the noise level of the machine by approximately 7 dB (0.7 B) compared to the Slimline 
doors. This reduction in noise emission levels means that the noise level of a single Eserver pSeries 
655 system with Slimline covers is about the same as the noise level of five Eserver pSeries 655 
systems with acoustical covers. 
v   ″Slimline″  Cover Option 
 This feature provides a smaller-footprint and lower-cost option for customers or sites where space is 
more critical than acoustical noise levels. The Slimline cover option consists of a front door, which is 
approximately 100 mm (4 in) deep, and a rear door, which is approximately 50 mm (2 in) deep. No 
acoustical treatment is available for this option.
Note:   For declared levels of acoustical noise emissions, refer to “Declared Acoustical Noise Emissions” on 
page 97. 
Moving the System to the Installation Site 
The customer should determine the path that must be taken to move the system from the delivery location 
to the installation site. The customer should verify that the height of all doorways, elevators, and so on are 
sufficient to allow moving the system to the installation site. The customer should also verify that the 
weight limitations of elevators, ramps, floors, floor tiles, and so on are sufficient to allow moving the
