Section-5, Checking the prerequisites on the customer provided rack
Procedure
- Locate the customer provided rack.
- The rack internal depth (EIA front rail to rear rail) must be 720 - 780 mm (28.4" to 30.7").
- The rack must have an empty location of EIA 16U (48 rail holes). Note: 1U = 3 mounting holes. See Figure 1.
Figure 1. EIA unit mounting holes 
- The customer must provide two power connectors for the DS8882F mainline power cables. Note: It is strongly recommended the customer use two different power sources.
- If the source power connectors are external to the rack, the mainline power cables are 4.3 meters.
- If the source power connectors are internal to the rack, the mainline power cables are less than 2 meters.
- Is the optional Feature Code 1765 (keyboard/display, 1U tray) listed in ship group?
- The two management consoles require a VGA and USB connection to a
keyboard/display function in the rack. The connections can be shared. Attention: The 983 has one VGA and one USB connection for each management console. There are two management consoles.
- If the 983 is being installed in an IBM ZR1 server rack (Feature Code 0937) or IBM LR1 servicer rack (Feature Code 0938), the rack already contains a keyboard/display with KVM switch. The KVM switch connections require the VGA/USB to 25 pin serial adapter cable that is provided by Feature Codes 0937/0938. If the adapter cable is not in the ship group, stop and call the next level of support.
- If the rack does not have an existing keyboard/display function, and the ship group does not list Feature Code 1765, STOP THE INSTALLATION. Work with the customer and next level of support to resolve the problem.
