Installing a Network Service Module

There are two methods for installing and removing NSMs: the Standard

Installation Method and the Hot Swap Installation Method. The software release running on your switch or router determines which of these two methods should be used.

If your switch or router is running Software Version 2.2.3 or earlier, follow the standard method. If your switch or router is running Software Version 2.3.1 or later, you can use the hot swap method.

To find out which software release your switch or router is running, use the command: show release

Standard Installation Method (for Software Version 2.2.3 or earlier):

Follow these steps to install or remove an NSM if the software release does not support hot swapping.

1.

Read the safety information

See the Safety and Statutory Information booklet for your switch or router. A copy of this booklet can be found on the CD-ROM that came with your switch or router, or at www.alliedtelesis.com/support/.

2.

If connected, disconnect the switch or router from its redundant power supply

3.

Disconnect the switch or router from the main power supply

If using the Standard Installation Method, be sure to disconnect the main power supply and the redundant power supply before installing an NSM.

Installing an NSM with this method when the switch or router is powered ON can damage the NSM.

4.

Remove the switch or router NSM-bay face-plate or existing NSM

If the switch or router does not have an NSM installed, remove the blank

NSM-bay face-plate by loosening the two M4 Phillips screws. See Figure 3 on page 5.

If an NSM is already installed, disconnect its network cables and TNV lines before removing it from the switch or router.

Remove the NSM by unscrewing both thumbscrews at the same time. As the thumbscrews are turned, they will push the NSM out of the bay.

If the NSM has extractor levers, moving them to the open position will

assist the removal process (Figure 2 on page 5).

Figure 2: NSM extractor levers.

Close

Open

When removing an NSM, take care to turn each thumbscrew by an equal amount to ensure the NSM does not become misaligned. Forcing a jammed thumbscrew may damage the NSM.

If a thumbscrew becomes tight, it must not be forced. Instead, screw it in or out slightly to loosen it and then try again, taking care to unscrew both thumbscrews at the same rate.

Keep the face-plate for future use. If you remove an NSM, replace the face-plate to prevent dust and debris from entering the switch or router and to maintain proper airflow.

Prepare the NSM

In an antistatic environment, remove the NSM from its packing material.

Be sure to observe ESD precautions.

Do not attempt to install an NSM without observing correct antistatic procedures. Failure to do so may damage the switch, router, or NSM. If you are unsure what the correct procedures are, contact your authorised Allied Telesis distributor or reseller.

6.

Slide the NSM into place

Slide the NSM into the NSM bay, making sure the ends of the thumbscrews are aligned with the screw holes on the switch or router.

If the NSM has extractor levers, they should be in the closed position

(Figure 2 on page 5).

7.

Secure the NSM

When the NSM has been firmly pushed into place, turn the NSM’s two thumbscrews to engage their threads. Tighten both thumbscrews at the same rate to pull the NSM into position.

The screws will tighten when the NSM panel is in its installed position. The thumbscrews should be firm but not over-tight.

If one thumbscrew becomes tight before the other, loosen it slightly before proceeding.

8.

Installing PICs in the AT-AR040 NSM

If you have PICs to install, install them now by following the Port Interface

Card Quick Install Guide. If there are more PIC bays than PICs, use the bays on the switch or router base unit first, then fill the NSM PIC bays starting with bay 0.

9.

Apply power to the switch or router by re-attaching the power cord

Check that the switch or router power LED lights green.

10. If you disconnected a redundant power supply, reconnect it

11. Verify the installation

Check the In Use LED. The In Use LED (on the switch or router rear panel) lights to indicate the NSM is installed, is receiving power, and is operational.

Use the show system command to verify the switch or router has recognised the NSM. If there is no NSM entry in the output, recognition has failed.

If the In Use LED fails to light or recognition fails, repeat the installation process, paying particular attention to steps 6 and 7.

If the reinstallation fails, see the Network Service Module Hardware Reference, which has further troubleshooting information.

Hot Swap Installation Method (for Software Version 2.3.1 or later):

WARNING: Failure to follow this procedure when hot swapping an NSM will cause the switch or router to crash, and may damage the switch or router and files stored in Flash.

The AT-AR040 NSM can be hot swapped with PICs installed in its PIC bays. There is no need to remove the PICs before hot swapping. See the NSM Hardware Reference for information on the operational characteristics of hot swapped interfaces.

C613-04019-01 REV J

Quick Install Guide 7

Follow these steps to hot swap an NSM.

1.

Prepare the NSM bay for hot swap

If the In Use LED (next to the NSM bay) is lit, use a pencil tip or similar object to press the recessed Hot Swap button. The In Use LED should go out and the Swap LED should light.

If the In Use LED remains lit or if neither the In Use or Swap LED are lit, the software release does not support hot swapping, and the Standard

Installation Method must be used.

Do not attempt to hot swap while the contents of Flash are being modified; for instance, during Flash compaction or when files are being loaded onto the switch or router. If the switch or router crashes while Flash is being modified, configuration files, software release files, feature licences and other files may be damaged.

2.

Prepare the NSM

In an antistatic environment, remove the NSM from its packing material.

Be sure to observe ESD precautions.

Do not attempt to install an NSM without observing correct antistatic procedures. Failure to do so may damage the switch, router, or NSM. If you are unsure what the correct procedures are, contact your authorised Allied Telesis distributor or reseller.

3.

Remove the switch or router NSM-bay face-plate or existing NSM

If the switch or router does not have an NSM installed, remove the blank

NSM-bay face-plate by loosening the two M4 Phillips screws. See Figure 3 on page 5.

If an NSM is already installed, disconnect its network cables and TNV lines before removing it from the switch or router.

Remove the NSM by unscrewing both thumbscrews at the same time. As the thumbscrews are turned, they will push the NSM out of the bay.

If the NSM has extractor levers, moving them to the open position will

assist the removal process (Figure 2 on page 5).

The screws will tighten when the NSM panel is in its installed position. The thumbscrews should be firm but not over-tight.

If one thumbscrew becomes tight before the other, loosen it slightly before proceeding.

6.

Installing PICs in the AT-AR040 NSM

If you have PICs to install, install them now by following the Port Interface

Card Quick Install Guide. If there are more PIC bays than PICs, use the bays on the switch or router base unit first, then fill the NSM PIC bays starting with bay 0.

7.

Return the NSM bay to use

Press the recessed Hot Swap button. The Swap LED will go out and the

In Use LED will light.

If the In Use LED lights only briefly and the Swap LED then lights continuously, the NSM is of a type the software release does not support.

8.

Verify the installation

Use the show system command to verify the switch or router has recognised the NSM. If there is no NSM entry in the output, recognition has failed.

If the In Use LED fails to light or recognition fails, repeat the installation process, paying particular attention to steps 4 and 5.

If the reinstallation fails, use the Standard Installation Method or see the

Network Service Module Hardware Reference, which has further troubleshooting information.
