Abstract

A drive carrier for a cold plug device of an information handling system includes a handle, a first latch, and a second latch. The handle rotates between a locked position and an unlocked position. The first latch includes first and second ends, and slides between first and second positions. The handle is held in the locked position when the first latch is in the first position. The second latch includes first and second ends. The first end of the second latch is pivotally attached to the second end of the first latch and the second end of the second latch snap fits over a first end of the handle. The second latch prevents the first latch from sliding from the first position to the second position when the second end of the second latch is snap fitted over the first end of the handle.

First claim

What is claimed is:

1. A drive carrier for a device of an information handling system, the drive carrier comprising: a front portion to be placed in physical communication with a front portion of the device, wherein the device is a cold plug device to be inserted within a server, the front portion of the drive carrier including: a handle rotatable between a locked position and an unlocked position on a first side of the front portion of the drive carrier; a first latch including first and second ends, the first latch to slide between a first position and a second position on a second side of the front portion of the drive carrier opposite to the first side, wherein the handle is held in the locked position when the first latch is in the first position; and a second latch including first and second ends, the first end of the second latch pivotally attached to the second end of the first latch, and the second end of the second latch to snap fit over a first end of the handle, wherein the second latch prevents the first latch from sliding from the first position to the second position when the second end of the second latch is snap fitted over the first end of the handle.

2. The drive carrier of claim 1 , further comprising:
first and second side portions, the first side portion to be placed in physical communication with a first side portion of the device and the second side portion to be placed in physical communication with a second side portion of the device.

3. The drive carrier of claim 1 , wherein the driver carrier and the device are secured within a slot of the server when the handle is in the locked position.

4. The drive carrier of claim 1 , wherein the second latch is in a locked position when the second end of the second latch is snap fitted over the first end of the handle, and is an unlocked position is substantially perpendicular to the first latch.

5. The drive carrier of claim 4 , wherein the first latch further includes a spring to bias the first latch towards the first position.

6. The drive carrier of claim 5 , wherein a first force exerted on the second latch is transferred to the first latch via a connection point between the first and second latches.

7. The drive carrier of claim 6 , wherein the first latch transitions from the first position to the second position in response to the first forced exerted being greater than a second force of the spring.

8. The drive carrier of claim 1 , wherein the second end of the second latch includes an insert to receive a hook portion on the first end of the cam lever.

9. An information handling system comprising: a bay including a plurality of slots; a device to be inserted within one of the slots of the bay, wherein the device is a cold plug device to be inserted within the information handling system; and a device carrier to be in physical communication with the device, the device carrier including: a front portion to be placed in physical communication with a front portion of the device, the front portion of the drive carrier including: a handle to rotate between a locked position and an unlocked position on a first side of the front portion of the drive carrier; a first latch including first and second ends, the first latch to slide between a first position and a second position on a second side of the front portion of the drive carrier opposite to the first side, wherein the handle is held in the locked position when the first latch is in the first position; and a second latch including first and second ends, the first end of the second latch pivotally attached to the second end of the first latch, and the second end of the second latch to snap fit over a first end of the handle, wherein the second latch prevents the first latch from sliding from the first position to the second position when the second end of the second latch is snap fitted over the first end of the handle.

10. The information handling system of claim 9 , further comprising:
first and second side portions, the first side portion to be placed in physical communication with a first side portion of the device and the second side portion to be placed in physical communication with a second side portion of the device.

11. The information handling system of claim 9 , wherein the driver carrier and the device are secured within a slot of the server when the handle is in the locked position.

12. The information handling system of claim 9 , wherein the second latch is in a locked position when the second end of the second latch is snap fitted over the first end of the handle, and is an unlocked position is substantially perpendicular to the first latch.

13. The information handling system of claim 12 , wherein the first latch further includes a spring to bias the first latch towards the first position.

14. The information handling system of claim 13 , wherein a first force exerted on the second latch is transferred to the first latch via a connection point between the first and second latches.

15. The information handling system of claim 14 , wherein the first latch transitions from the first position to the second position in response to the first forced exerted being greater than a second force of the spring.

16. The information handling system of claim 9 , wherein the second end of the second latch includes an insert to receive a hook portion on the first end of the cam lever.
