Replacing A Modular Drive Bay Assembly - Cisco UCS C260 Installation And Service Manual

Installing or Replacing Server Components

Replacing a Modular Drive Bay Assembly

This server allows modular configuration of the drive bays, so that you can use one or two drive bays
depending on your needs.
Each drive bay assembly includes the chassis-steel drive bay, the attached drive backplane, and a
transition card (expander or nonexpander version) that provides connection to your RAID controllers
and the motherboard.

Each of the two modular chassis drive bays can hold up to eight 2.5-inch drives.
Each drive backplane connects to one transition card. The transition card connects the drive
backplane to the motherboard and connects to cables from your RAID controller.
The transition card is available in two versions:
– Nonexpander—Two internal connections to the RAID controller card are required to control
eight drives. This version includes two connectors for the cables from your RAID controller.
One of the connectors allows control of drives 1 through 4 on the backplane. The other
connector allows control of drives 5 through 8 on the backplane.
Expander—One internal connection to the RAID controller card is required to control eight
–
drives. This one connectors allows control of drives 1 through 8 on the backplane.
To use more than eight 2.5-inch drives in the server (up to 16), two drive bay modules are required,
each with its own backplane and transition card.
