How to Replace an NMS (Netra Modular System) Switch

Solution

CAP PROBLEM OVERVIEW:

The Netra modular system can have up to six Ethernet switches. They work as redundant pairs and can only be purchased in configurations of 2, 4, or 6. Replacing one of a redundant pair can be done such as to not impact node and data network operation of a live system. However, due to the complexity of this operation, you might want to replace switches during a scheduled maintenance or non-peak usage period.

DISPATCH INSTRUCTIONS

WHAT SKILLS DOES THE ENGINEER NEED:
Netra Modular System Training

TIME ESTIMATE: 60 minutes

TASK COMPLEXITY: 3

FIELD ENGINEER INSTRUCTIONS

It is recommended before arriving on site to review the process in the service manual supplement as it contains graphic and additional information that is too large or too complex to fix into this text only CAP.

Tools Needed:
#3 Phillips screwdriver - recommended magnetic with 6" minimum shaft.  A 12-16" works best on this system.

WHAT STATE SHOULD THE SYSTEM BE IN TO BE READY TO PERFORM THE RESOLUTION ACTIVITY? :

NOTE:  DO NOT CONNECT THE POWER CORDS UNTIL INSTRUCTED.

Remove an Ethernet Switch

1. Follow the safety and ESD precautions.

2. Locate the faulty switch. Slots are marked on the right side of the frame, both front and rear.

3. If  ASR is configured, deactivate the switch ASR asset.

4. Power down the switch.

5. At the front of the system:

a. Remove the filler panel at the faulty switch’s level.

Note – Depending on the switch location, it may be helpful to remove several filler panels.

Note – If removing the switch at level 35, and a node is not installed at level 34, remove the filler panel at level 34.

b. To keep the power cords out of the way, carefully make a loop and pull the cable through the above rail slot and out of the switch rail slot then tie it up. You cannot tie it up to its own rail as it is being removed with the switch.

Note – Power cords feed through the mounting brackets and can easily fall into the side panels when removed. Securing them with ties prevents you from having to pull them out of the side panel.

c. Disconnect the switch power cords from the power supplies.

6. At the rear of the modular system:

a. Locate the switch to be replaced (LEDs are not lit).
b. Remove all cables from the switch ports, noting the locations for later when installing the replacement switch. The cable ends are labeled with the switch and switch port numbers.

Caution – The switch is on slide rails. Do not remove the rail screws at the rear.

Caution – Do not attempt to remove the switch from the rear of the system.

c. If removing a switch at slot 37:
  i. Separate the fiber cables from the fiber cable tray.
  ii. Remove the fiber cable tray.
  iii. Remove the fiber cable tray brackets.

7. At the front of the modular system:

a. Remove the screws that attach the mounting brackets to the modular system cabinet.

Caution – In the next step, be sure to support the switch, because the switch is supported by the rails only until it is about 10" from being removed. After that, if unsupported, it will fall.

b. Carefully slide the switch completely out, and take it to an antistatic workbench.

8. On an antistatic workbench:

a. Remove the rail guides and mounting brackets from the faulty switch.
b. Install the rail guides and mounting brackets on the replacement switch.
c. Transfer the transceivers from the faulty switch to the same ports on the replacement switch.

9. Install the replacement switch.

Install an Ethernet Switch

1. Follow the safety and ESD precautions.

2. If installing a switch that has another component directly below and a component directly above, remove both of that switch’s rails at the rear of the modular system.

Note – Do not remove these rails if the slot below the switch is empty.

3. At the front of the modular system:

Caution – If installing a switch at slot 35 and a node is not present in slot 34, take extra precautions that rear slide rails are engaged as you insert the switch.

a. Carefully slide the replacement switch completely in.
b. Feed the power cords through the mounting bracket.

NOTE:  DO NOT PLUG IN THE POWER CORDS YET.

c. Tighten the screws that attach the mounting brackets to the modular system cabinet.
d. Install the filler panels,

4. At the rear of the modular system:
a. Reconnect all cables to the switch ports. The locations you noted when removing the faulty switch. Data cables are labeled Uxx, PT-xx, where xx is the port number.
b. Connect the NET MGT and NET SER cables.
c. Connect the switch power cords from the power supplies.
d. If you removed switch rails, reinstall them.
e. If you removed the switch at slot 37:

i. Reinstall the fiber cable tray.
ii. Reattach the fiber cables to the tray.

5. Refer to the switch documentation to power on the unconfigured switch, and, if needed, update the firmware.

You might need to obtain a patch release (such as 21378426) with the .pkg images for SP and HOST to update and configure the new switch. In the switch README, find the instructions to update the firmware on the switch.

6. Re-activate the switch in ASR if needed.
