AT-AR048 Support
Maximum DS3 packet forwarding rates are achieved only when the AT-AR048 is
installed in a Rapier 48w switch, or a Rapier 24iswitch whose serial number ends
with the letter N or higher. If maximum DS3 performance is not required, you can
install the AT-AR048 in any Rapier 24iwhose serial number ends with the letter J or
higher. You can find the serial number on the underside of the switch, as shown in
the following figure.

Hot Swapping
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 system
The following installation procedure describes how to install an NSM using either
installation method.
Hot swapping an AT-AR040
Caution You cannot install PICs into an AT-AR040 NSM that has power applied to
it. This includes NSMs that have been deactivated using the hot swap button, but not
physically removed from the switch or router. To ensure that all power is removed
from the NSM bay, you must either physically remove it from the switch or router
using the hot swap method, or disconnect all power sources to the switch or router.
If you are installing an AT-AR040 NSM and you have PICs to install, follow the Port
Interface Card Installation and Safety Guide. You can download this document from
www.alliedtelesis.com/support/software/. 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.
You can hot swap the AT-AR040 NSM with PICs already installed in its PIC bays.
There is no need to remove the PICs before hot swapping. See the Network Service
Module Hardware Reference for information on the operational characteristics of hot
swapped interfaces. You can download this document from
www.alliedtelesis.com/support/software/.

Installation and Safety Guide 7
613-000610 Rev B
Installing a Network Service Module
Warning Failure to follow this procedure when hot swapping an NSM will cause the
switch or router to halt, and may damage it and any files stored in flash memory.
1. Read the safety information.
See the Installation and Safety Guide or Safety and Statutory Information
Booklet for your switch or router. You can download this document
www.alliedtelesis.com/support/software/.
2. If you are not hot swapping, remove power to the switch or router.
Warning Be sure to disconnect the main power supply and the redundant
power supply before installing the NSM. Installing an NSM with the switch or
router powered on can damage the NSM or base unit.
3. If you are hot swapping, prepare the NSM bay.
Warning 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 halts while flash is being
modified, configuration files, software release files, feature licenses and other
files may be damaged.
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 nor Swap LED are lit, the
software release does not support hot swapping, and you must install the NSM
with the switch or router powered off.
4. Remove the faceplate or existing NSM.
If the switch or router does not have an NSM installed, remove the blank
faceplate by loosening the two captive screws, as shown in the following figure.

613-000610 Rev B
If an NSM is already installed, disconnect all network cables and TNV lines
before removing the NSM from the switch or router.
Remove the NSM by unscrewing both captive screws at the same time. As the
captive screws 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, as shown in the following figure.
When removing an NSM, take care to turn each captive screw by an equal
amount to ensure the NSM does not become misaligned. Forcing a jammed
captive screw may damage the NSM.
If a captive screw 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 captive
screws at the same rate.
Keep the faceplate for future use. If you remove an NSM, replace the faceplate
to prevent dust and debris from entering the switch or router and to maintain
proper airflow.
5. Prepare the NSM.
In an antistatic environment, remove the NSM from its packing material. Be
sure to observe ESD precautions.
Warning 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 captive screws
are aligned with the screw holes on the switch or router.
If the NSM has extractor levers, they should be in the closed position.
7. Secure the NSM.
When the NSM has been firmly pushed into place, turn the two captive screws
to engage their threads. Tighten both captive screws at the same rate to pull
the NSM into position.
The screws will tighten when the NSM panel is in its installed position. The
captive screws should be firm but not over-tight.
If one captive screw becomes tight before the other, loosen it slightly before
proceeding.
8. If you are not hot swapping, apply power to the switch or router.
Re-attach the power cord, and reconnect any redundant power supply. Check
that the switch or router power LED lights green.
Check the In Use LED on the switch or router rear panel. The In Use LED
lights to indicate the NSM is installed, is receiving power, and is operational.
9. If you are hot swapping, 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 not supported by the current software release.
10. Verify the installation.
Use the show system command to verify that the switch or router has
recognised the NSM. If the NSM does not appear in the list of boards at the top
of the display, or the In Use LED fails to light, then the switch or router has not
recognised the NSM. Likely reasons are:
• Your switch or router does not support the NSM. See “Compatible Switches
and Routers” on page 4.
• The NSM is not installed correctly. Repeat the installation process, paying
particular attention to steps 6 and 7.
If the installation still fails, see the Network Service Module Hardware Reference,
which has further troubleshooting information.
