Abstract

A connector replacement method in a network element chassis includes obtaining physical access to a backplane in the network element chassis, while the network element chassis is deployed; powering down backplane connectors for replacement while other backplane connectors remained powered; removing the powered down backplane connectors with a connector removal tool; inserting a new set of backplane connectors in place of the removed, powered down backplane connectors with a connector insertion tool; and powering up the new set of backplane connectors.

First claim

What is claimed is:

1. A connector replacement method in a network element chassis utilizing associated tools, the connector replacement method comprising:
obtaining a connector insertion tool comprising a housing, a handle, a vise configured to move based on rotation of the handle, a push out block configured to move based on movement of the vise, and a plurality of pins on the push out block arranged based on backplane connectors for replacement and configured to push out the backplane connectors for replacement based on movement of the push out block;
obtaining a connector removal tool comprising a housing, a handle, a vise configured to move based on rotation of the handle, a push in block configured to move based on movement of the vise, and a connector block on the housing opposing the push in block;
at a location where the network element chassis is physically deployed and operating in-service, obtaining physical access to a backplane in the network element chassis;
powering down backplane connectors for replacement while other backplane connectors remained powered;
removing the powered down backplane connectors with the connector removal tool;
inserting a new set of backplane connectors in place of the removed, powered down backplane connectors with the connector insertion tool; and
powering up the new set of backplane connectors.

2. The connector replacement method of claim 1 , further comprising:
installing a backplane safety cover over the physical access for protection of the backplane and the other backplane connectors during operation on the backplane connectors for replacement.

3. The connector replacement method of claim 2 , wherein the backplane safety cover comprises an open portion for selective access to the backplane and one or more doors for selective access to the backplane connectors.

4. The connector replacement method of claim 1 , wherein the backplane connectors for replacement comprise fan connectors, and the method further comprising:
installing an externally powered temporary fan unit subsequent to powering down the backplane connectors for replacement, enabling cooling during the method while the network element chassis is in-service.

5. The connector replacement method of claim 4 , wherein the backplane connectors for replacement comprise fan connectors, and wherein temporary cooling is performed in the network element chassis while the backplane connectors for replacement are powered down.

6. A connector replacement method in a network element chassis utilizing associated tools, the connector replacement method comprising:
obtaining a connector insertion tool comprising a housing, a handle, a vise configured to move based on rotation of the handle, a push out block configured to move based on movement of the vise, and a plurality of pins on the push out block arranged based on backplane connectors for replacement and configured to push out the backplane connectors for replacement based on movement of the push out block;
obtaining a connector removal tool comprising a housing, a handle, a vise configured to move based on rotation of the handle, a push in block configured to move based on movement of the vise, and a connector block on the housing opposing the push in block;
at a location where the network element chassis is physically deployed and operating in-service, obtaining physical access to a backplane in the network element chassis;
powering down backplane connectors for replacement while other backplane connectors remained powered;
installing a backplane safety cover over the physical access for protection of the backplane and the other backplane connectors during operation on the backplane connectors for replacement;
removing the powered down backplane connectors with the connector removal tool;
inserting a new set of backplane connectors in place of the removed, powered down backplane connectors with the connector insertion tool; and
powering up the new set of backplane connectors.

7. The connector replacement method of claim 6 , wherein the backplane safety cover comprises an open portion for selective access to the backplane and one or more doors for selective access to the backplane connectors.

8. The connector replacement method of claim 6 , wherein the connector removal tool and the connector insertion tool are configured to operate on the powered down backplane connectors on one of a top portion of the backplane and a bottom portion of the backplane.

9. The connector replacement method of claim 6 , wherein the backplane connectors for replacement comprise fan connectors, and the method further comprising:
installing an externally powered temporary fan unit subsequent to powering down the backplane connectors for replacement, enabling cooling during the method while the network element chassis is in-service.

10. The connector replacement method of claim 9 , wherein the backplane connectors for replacement comprise fan connectors, and wherein temporary cooling is performed in the network element chassis while the backplane connectors for replacement are powered down.

11. A connector replacement method in a network element chassis utilizing associated tools, the connector replacement method comprising:
obtaining a connector insertion tool comprising a housing, a handle, a vise configured to move based on rotation of the handle, a push out block configured to move based on movement of the vise, and a plurality of pins on the push out block arranged based on backplane connectors for replacement and configured to push out the backplane connectors for replacement based on movement of the push out block;
obtaining a connector removal tool comprising a housing, a handle, a vise configured to move based on rotation of the handle, a push in block configured to move based on movement of the vise, and a connector block on the housing opposing the push in block;
at a location where the network element chassis is physically deployed and operating in-service, obtaining physical access to a backplane in the network element chassis;
powering down backplane connectors for replacement while other backplane connectors remained powered, wherein the backplane connectors for replacement comprise fan connectors;
installing an externally powered temporary fan unit subsequent to powering down the backplane connectors for replacement, enabling cooling during the method while the network element chassis is in-service;
removing the powered down backplane connectors with the connector removal tool;
inserting a new set of backplane connectors in place of the removed, powered down backplane connectors with the connector insertion tool; and
powering up the new set of backplane connectors.

12. The connector replacement method of claim 11 , further comprising:
installing a backplane safety cover over the physical access for protection of the backplane and the other backplane connectors during operation on the backplane connectors for replacement.

13. The connector replacement method of claim 12 , wherein the backplane safety cover comprises an open portion for selective access to the backplane and one or more doors for selective access to the backplane connectors.

14. The connector replacement method of claim 11 , wherein the connector removal tool and the connector insertion tool are configured to operate on the powered down backplane connectors on one of a top portion of the backplane and a bottom portion of the backplane.

15. The connector replacement method of claim 11 , wherein the backplane connectors for replacement comprise fan connectors, and wherein temporary cooling
