Before You Begin
The article below provides information about safe practices to consider before working with electrical equipment.
Two side-by-side pairs will be treated as a single FlexBay (Figure 1). The backplane consists of two pairs, so it must be replaced on a FlexBay basis.

Removal Instructions

| 1 | Phillips screwdriver with shaft length × 20cm (+2×200) |
| 2/3 | 2.0/2.5mm Plus Driver |
Note: Be aware that using a large Phillips or Flat Head screwdriver may result in damage to the head of the screws. This would make their removal impossible without specialty tools, that are not available to our onsite engineers.
The following parts will be required to replace SATA/SAS with PCIe SSD.
- [575-BBSH] - M.2 Module for FlexBay incl. carrier 58/78/7920 Towers (Kit)

- [750-ABDF] - Convert HDD FlexBay to PCIe SSD FlexBay 58/78 Towers (Kit)
