Chapter 5. Drives
5.1. Requirements for DE6000H drive replacement
Before you replace a drive, review the requirements and considerations.
5.1.1. Shelf types
You can replace a drive in a 24-drive shelf, in a 60-drive shelf, or in a drive drawer.
This procedure applies to IOM12 and IOM12B drive shelves, and DCM and DCM2 drive shelves.
This procedure is for like-for-like shelf IOM hot-swaps or replacements. This
means you can only replace an IOM12 module with another IOM12 module or
replace an IOM12B module with another IOM12B module. (Your shelf can have
two IOM12 modules or have two IOM12B modules.)
24-drive shelves
The figures show how the drives are numbered in each type of shelf (the shelf’s front bezel or end
caps have been removed).
Drive numbering in a DE6000H (2U24) controller shelf or DE240S drive shelf
60-drive shelves
Both the DE6000H (4U60) controller shelf and the DE240S drive shelf consist of five drive drawers
that each contain 12 drive slots. Drive drawer 1 is at the top, and drive drawer 5 is at the bottom.
