Abstract

A digital data handling unit has a manually graspable part operable for removal of the unit from a digital data handling host. The manually graspable part includes an illuminable portion which, when illuminated, serves to distinguishably identify a particular digital data handling unit. The illuminable portion may be an illuminable strip. The digital data handling unit may be one of a data processing unit, a data storage unit, a data controller subsystem unit or a data communication unit.

First claim

What is claimed is:

1. A component rack, comprising:
a plurality of vertically aligned slots configured to receive digital data handling units, and to couple the digital data handling units to a host computer;
a plurality of digital data handling units inserted into the plurality of vertically aligned slots, each digital data handling unit including a front surface that is visible and accessible when inserted into one of the slots;
each of the plurality of digital data handling units includes a latching mechanism that lockingly retains the digital data handling unit in a slot, and a handle that is linked to the latching mechanism and is manually accessible at the front surface of the digital data handling unit when the digital data handling unit is inserted in a slot;
the handle is moveably attached to the digital data handling unit by a hinged attachment point at one end of the handle that allows the unattached end of the handle to be moved from a position adjacent to the front face of the digital data handling unit outward from the front face of the digital data handling unit;
the handle is operated such that by moving the handle outward from the front face of the digital data handling unit, the latching mechanism unlocks the digital data handling unit in the slot to enable the removal of the digital data handling unit from the component rack;
the handle further includes an illuminable portion that is visible at the front face of the digital data handling unit, wherein illuminating the illuminable portion is controlled by a processor in the digital data handling unit to indicate that the digital data handling unit is in an operational state suitable for removal from the component rack, and to further indicate the particular handle to operate to remove the digital data handling unit from the component rack.

2. A component rack in accordance with claim 1 , wherein the illuminable portion covers a substantial portion of the first part of the handle that is visible when the digital data handling unit is inserted into a slot.

3. A component rack in accordance with claim 2 , wherein the substantial portion is at least 10 percent.

4. A component rack in accordance with claim 1 , wherein the illuminable portion comprises an illuminable strip.

5. A component rack in accordance with claim 1 , wherein the illuminable portion is illuminated in response to an abnormal condition of the digital data handling unit.

6. A component rack in accordance with claim 1 , wherein the illuminable portion comprises one of: a fiber optically illuminated portion, a liquid crystal display portion, or a light emitting diode portion.

7. A component rack in accordance with claim 1 , wherein the illuminable portion illuminates in a plurality of colors, wherein different colors indicate different operational states of the digital data handling unit.
