Maintaining MX480 Switch Control Boards
Replacing an MX480 Switch Control Board
Before replacing a Switch Control Board (SCB), read the guidelines in Operating and Positioning the MX480 SCB Ejectors.
Removing an MX480 SCB-MX
- Take the host subsystem offline.
- Place an electrostatic bag or antistatic mat on a flat, stable surface.
- Attach an ESD grounding strap to your bare wrist and connect the strap to one of the ESD points on the chassis.
- Rotate the ejector handles simultaneously counterclockwise to unseat the Switch Control Board.
- Grasp the ejector handles, and slide the Switch Control Board about halfway out of the chassis.
- Place one hand underneath the Switch Control Board to support it, and slide it completely out of the chassis.
- Place the Switch Control Board on the antistatic mat.
- If you are not replacing the Switch Control Board now, install a blank panel over the empty slot.

Installing an MX480 Switch Control Board
- Wrap and fasten one end of the ESD grounding strap around your bare wrist, and connect the other end of the strap to the ESD point on the chassis.
- Carefully align the sides of the Switch Control Board with the guides inside the chassis.
- Slide the Switch Control Board into the chassis until you feel resistance, carefully ensuring that it is correctly aligned.
- Grasp both ejector handles, and rotate them simultaneously clockwise until the Switch Control Board is fully seated.
- Place the ejector handles in the proper position, horizontally and
toward the center of the board.

Upgrading an MX480 to Use the SCBE-MX
This topic describes how to upgrade your MX960, MX480, or MX240 router to use the SCBE-MX without taking the router offline. This “in-service” upgrade only works for MX routers with DPC, MS-DPC, MPC1, MPC2, or MPC3 line cards. If your MX router has another type of line card, you’ll need to take the router offline before you do the upgrade.
Junos OS does not support in-service upgrades to the SCBE-MX on routers with an MX-MPC3E-3D or MX-MPC3-3D MPC. If your MX router has these MPCs, you’ll need to shutdown the system before you do the upgrade. An in-service upgrade can result in service disruption.
Prepare for the Upgrade
Before you do the upgrade, open a telnet session to the master Routing Engine CLI operational mode and issue the configure exclusive command. This command locks the configuration to prevent accidental changes during the upgrade process.
To prevent traffic loss during the upgrade process, we recommend that you operate the line cards at 50% line rate. This 50% limit must be maintained per PFE on each line card.
To prepare the MX480 router for the Enhanced MX Switch Control Board (SCBE-MX) upgrade:
- Verify that the system runs Junos OS Release 11.4 or later
by issuing the show version command on the master router.
user@host> show version
Model: mx480 Junos Base OS Software Suite [11.4-20110530];
Note The MX SCBE-MX is supported only in Junos OS Release 11.4 or later.
The latest software ensures a healthy system—that is, Routing Engines, control boards, and FPCs—before the upgrade.
- Verify that SCB-MX boards are installed:
user@host> show chassis hardware
Item Version Part Number Serial Number Description
CB0 REV 07 710-021523 ABBC8281 MX SCB CB1 REV 07 710-021523 ABBC8323 MX SCBSCB-MX details are displayed as above, along with other hardware components. The MX480 router has only two SCB-MXs and each SCB-MX has four fabric planes.
- Establish console connections to both Routing Engines. You can use a telnet session to connect to the router console by issuing the <router name>-con command. For example, if the router name is juniper, you can connect to RE0 and RE1 consoles by issuing the telnet juniper-con and telnet juniper1-con commands.
- Ensure that graceful switchover (GRES), commit synchronize
(required for nonstop routing), and nonstop routing (NSR) are enabled
or configured by running the set chassis redundancy graceful-switchover,
set system commit synchronize, set routing-options nonstop-routing commands.
Note These commands are mandatory for this upgrade and may be removed, if desired, after the upgrade.
- Set the upgrade flag on, and start the SCB-MX upgrade
by issuing the set chassis state cb-upgrade on command.
user@host# configure
user@host# set chassis state cb-upgrade on
user@host# commit
- Determine the order to replace the existing SCB-MXs with
upgraded ones. SCB 0 is associated with RE0, and SCB 1 is associated
with RE1.
Note Do not add or remove any router hardware during the upgrade procedure.
Upgrade the SCB-MX in the Backup Routing Engine
The MX480 has two slots for the SCB-MX—that is, SCB 0 and SCB 1—and these correspond to RE0 and RE1 respectively, where SCB 1 is the first SCB-MX.
To upgrade the SCB-MX in the backup Routing Engine:
- Power down the backup Routing Engine from the master Routing Engine by issuing the request system power-off other-routing-engine command.
- Verify that the Routing Engine is powered down by issuing
the show chassis routing-engine 1 command. The slot of
the Routing Engine may be 0 or 1, and is shown as 1 in this example:
user@host> show chassis routing-engine 1
Routing Engine Status: Slot 1: Current State Present
Ensure that the Current State is Present, which indicates that the Routing Engine is offline.
- Take the fabric plane offline by issuing the request chassis fabric plane 4 offline command. SCB 1 has four fabric planes numbered, 4, 5, 6, and 7.
- Verify that the fabric plane 4 is offline by issuing the show chassis fabric summary command.
user@host> show chassis fabric summary
Plane State Uptime 4 Offline 5 Online 1 hour, 15 minutes, 35 seconds
- Take the remaining fabric planes offline by issuing the request chassis fabric plane 5/6/7 offline command—that is, by changing the fabric plane number each time. Verify that the fabric planes are offline by issuing the command given in Step 2.
- Take the SCB-MX in slot 1 offline by issuing the request chassis cb offline slot 1 command.
- Verify that SCB-MX is offline:
user@host> show chassis environment cb 1
CB 1 status: State Offline Power 1 Disabled Power 2 Disabled
- Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.
- Remove and replace the SCB-MX in slot 1 on the router with the SCBE-MX. Use the replacement procedure described in Replacing an MX480 Switch Control Board.
- Verify that the installation is successful and the SCBE-MX
is online:
user@host> show chassis environment cb 1
CB 1 status State Online Temperature 30 degrees C / 86 degrees F
- Verify that the fabric planes come online correctly:
user@host> show chassis fabric summary
Plane State Uptime 4 Online 2 minutes, 25 seconds 5 Online 2 minutes, 15 seconds 6 Online 2 minutes, 3 seconds 7 Online 1 minute, 49 seconds
- Verify that the backup Routing Engine is back online:
user@host> show chassis routing-engine 1
Routing Engine Status: Slot 1: Current State Backup
- Verify the alarms:
user@host> show chassis alarms
Alarm Time Class Description 2011-06-01 13:26:56 EDT Major CB fabrics are of mixed types
As only one SCB-MX has been upgraded, the alarm indicates that the SCB-MXs are of mixed type. This alarm is cleared after all the control boards are upgraded.
Upgrade the MX480 SCB-MX in the Master Routing Engine
- Issue the request chassis routing-engine master switch command so that the backup RE becomes the master RE. This ensures a Graceful RE Switchover (GRES) to gracefully switch between the master and backup Routing Engines.
- Log in to the new master Routing Engine after the switchover.
- Switch the configuration mode to ensure that you are still in configure exclusive mode by issuing the exit command and then the configure exclusive command, from the old master Routing Engine.
- Log in to the current master Routing Engine again and issue the configure exclusive command.
- Power down the backup Routing Engine from the master Routing Engine by issuing the request system power-off other-routing-engine command.
- Issue the show chassis routing-engine 0 command
to verify that the Routing Engine is powered down.
user@host> show chassis routing-engine 0
Routing Engine Status: Slot 0: Current State Present
Verify that the Current State is Present, which indicates that the Routing Engine is offline.
- Take the first fabric plane of the backup Routing Engine offline by issuing the request chassis fabric plane 0 offline command. SCB0 has four fabric planes numbered, 0, 1, 2, and 3.
- Issue the show chassis fabric summary command
to verify that the fabric plane is offline.
user@host> show chassis fabric summary
Plane State Uptime 0 Offline 1 Online 3 minutes, 45 seconds
Verify that the state of plane 0 is Offline.
- Take the remaining fabric planes offline by issuing the request chassis fabric plane 1/2/3 offline command—that is, by changing the fabric plane number each time. Verify that the fabric planes are offline by issuing the command given in Step 4.
- Take the SCB-MX in slot 0 offline by issuing the request chassis cb offline slot 0 command.
- Verify that the control board is offline:
user@host> show chassis environment cb 0
CB 0 status: State Offline Power 1 Disabled Power 2 Disabled
- Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.
- Remove and replace the offline SCB-MX on the router with the SCBE-MX. Use the replacement procedure described in Replacing an MX480 Switch Control Board.
- Verify that the installation is successful and SCB 0 is
online by issuing the show chassis environment cb 0 command:
user@host> show chassis environment cb 0
CB 0 status State Online Temperature 30 degrees C / 86 degrees F
Other details, such as power, are also displayed along with the state.
- Verify that the fabric planes come online correctly by
issuing the show chassis fabric summary command:
user@host> show chassis fabric summary
Plane State Uptime 0 Online 2 minutes, 5 seconds 1 Online 1 minute, 55 seconds 2 Online 1 minute, 43 seconds 3 Online 1 minute, 33 seconds
- Verify that the backup Routing Engine is back online by
issuing the show chassis routing-engine 0 command:
user@host> show chassis routing-engine 0
Routing Engine Status: Slot 0: Current State Backup
- Verify the alarms by issuing the show chassis alarms command:
user@host> show chassis alarms
Alarm Time Class Description 2011-06-01 13:26:56 EDT Major CB fabric links require upgrade/training 2011-06-01 12:10:41 EDT Major Require a fan tray upgrade
The major alarm has changed from
CB fabrics are of mixed types
toCB fabric links require upgrade/training
, as a SCB-MX requires training to change the link speed from 3G to 6G for the SCBE-MX. This alarm is displayed until the 3G to 6G link transition is completed.
Complete the SCBE-MX Upgrade
- Verify if there are any MPCs running at 3G instead of
6G:
user@host> request chassis fabric upgrade-bandwidth info
Slot State 0 Upgrade not supported 1 Needs upgrade 2 Empty 3 Empty 4 Empty 5 Empty
In this example, the results indicate that slot 0 does not support the upgrade and slot 1 needs to be upgraded.
Note The SCBE-MX line card supports only DPC, MS-DPC, MPC1, MPC2, and MPC3 line cards for the upgrade-bandwidthcommand. If line cards that do not support the upgrade-bandwidthcommand are present in the chassis during the SCB-MX to SCBE-MX upgrade, the request chassis fabric upgrade-bandwidth commands will return Upgrade not supported for the slot(s) that contain the unsupported line card(s).
- Issue the request chassis fabric upgrade-bandwidth
fpc all command to upgrade the bandwidth of all MPCs. If you
want to control the MPC line card upgrade, go to Step 3.
Caution Use this command only if you are not concerned with the slot upgrade order or if only one old MPC is present in the chassis. Running this command may result in a loss of traffic across the MPC. Using this method may increase the traffic loss, because it does not consider any redundancy or graceful switchover strategies that you may have configured on the system.
- Issue the request chassis fabric upgrade-bandwidth fpc slot 1 command to upgrade the MPC in slot 1.
- Verify that the MPC is upgraded:
user@host> request chassis fabric upgrade-bandwidth info
Slot State 0 Upgrade not supported 1 Upgraded 2 Empty
- Verify the fabric plane state for all MPCs:
user@host> show chassis fabric summary
Plane State Uptime 0 Spare 21 seconds 1 Spare 12 seconds 2 Online 12 minutes 3 Online 12 minutes 4 Online 30 minutes 5 Online 30 minutes
- Verify the state of the MPCs:
user@host> show chassis fabric fpcs
FPC 1 PFE #0 Plane 0: Links ok Plane 1: Links ok Plane 2: Plane enabled Plane 3: Plane enabled Plane 4: Plane enabled Plane 5: Plane enabled PFE #1 Plane 0: Links ok Plane 1: Links ok Plane 2: Plane enabled Plane 3: Plane enabled Plane 4: Plane enabled Plane 5: Plane enabled PFE #2 Plane 0: Links ok Plane 1: Links ok Plane 2: Plane enabled Plane 3: Plane enabled Plane 4: Plane enabled Plane 5: Plane enabled PFE #3 Plane 0: Links ok Plane 1: Links ok Plane 2: Plane enabled Plane 3: Plane enabled Plane 4: Plane enabled Plane 5: Plane enabled
Fabric plane details of all MPCs are also displayed.
- Verify if the show chassis fabric summary command
output shows fabric planes in the 'check' state. This indicates that
the fabric plane has an error. You can try to recover the fabric plane
to normal operation by issuing the request chassis fabric plane
<#> offline command, followed by the request chassis
fabric plane <#> online command, where <#> equals the
fabric plane in error.
Note After you issue the request chassis fabric plane <#> offline and request chassis fabric plane <#> online commands, issue the show chassis fabric summary command to verify that the fabric plane errors are rectified and to verify the current state of the fabric planes.
- Verify if there are any major alarms:
user@host> show chassis alarms
Alarm Time Class Description 2011-06-01 13:37:43 EDT Minor Require a fan tray upgrade 2011-06-01 13:37:26 EDT Minor Backup RE Active
In this example, the major alarms are no longer displayed, and the upgrade is successfully completed.
- Disable the upgrade configuration by issuing the set chassis state cb-upgrade off command and then the commit command.
- You can delete that command by issuing the delete
chassis state cb-upgrade command and then the commit command.
Warning Deleting the chassis state cb-upgrade on configuration before disabling the SCB-MX upgrade using the set chassis state cb-upgrade off command can cause unexpected errors in the fabric.
- Verify the SCBE-MXs are installed by issuing the show chassis hardware command:
user@host> show chassis hardware

For information about how to verify and upgrade the Junos OS, see the Junos OS Installation and Upgrade Guide.
Power Off the MX480 Router
After turning off the power supply, wait at least 60 seconds before turning it back on.
- On the external management device connected to the Routing
Engine, issue the request system halt both-routing-engines operational mode command. This command shuts down the Routing Engines
cleanly, so that their state information is preserved. (If the router contains
only one Routing Engine, issue the request system halt command.)
user@host> request system halt both-routing-engines
- Wait until a message appears on the console confirming that the operating system has halted.
- Attach an electrostatic discharge (ESD) grounding strap to your bare wrist and connect the strap to one of the ESD points on the chassis.
- Move the AC input switch on the chassis above the AC power
supply or the DC circuit breaker on each DC power supply faceplate
to the off
(O)
position.
Remove the MX480 Routing Engine
- Remove the cables connected to the Routing Engine.
- Place an electrostatic bag or antistatic mat on a flat, stable surface.
- Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.
- Loosen the captive screws on the top and bottom of the Routing Engine.
- Flip the ejector handles outward to unseat the Routing Engine.
- Grasp the Routing Engine by the ejector handles, and slide it about halfway out of the chassis.
- Place one hand underneath the Routing Engine to support it, and slide it completely out of the chassis.
- Place the Routing Engine on the antistatic mat.
Install the MX480 Routing Engine into the SCBE2-MX
- Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.
- Ensure that the ejector handles are not in the locked position. If necessary, flip the ejector handles outward.
- Place one hand underneath the Routing Engine to support it.

- Slide the Routing Engine into the SCBE2-MX until you feel resistance and then press the faceplate of the Routing Engine until it engages the connectors.
- Press both of the ejector handles inward to seat the Routing Engine.
- Tighten the captive screws on the top and bottom of the Routing Engine.
- Connect the management device cables to the Routing Engine.
Power On the MX480 Router
- Verify that the power supplies are fully inserted in the chassis.
- Verify that each AC power cord is securely inserted into its appliance inlet.
- Verify that an external management device is connected
to one of the Routing Engine ports (
AUX
,CONSOLE
, orETHERNET
). - Turn on the power to the external management device.
- Switch on the dedicated customer-site circuit breakers. Follow the ESD and safety instructions for your site.
- Attach an ESD grounding strap to your bare wrist and connect the strap to one of the ESD points on the chassis.
- Move the AC input switch on the chassis above the AC power
supply or the DC circuit breaker on each DC power-supply faceplate
to the off

position. - Check that the AC or the DC power supply is correctly
installed and functioning normally. Verify that the
AC OK
andDC OK
LEDs light steadily, and thePS FAIL
LED is not lit.Note After a power supply is powered on, it can take up to 60 seconds for status indicators—such as the status LEDs on the power supply and the show chassis command display—to indicate that the power supply is functioning normally. Ignore error indicators that appear during the first 60 seconds.
If any of the status LEDs indicates that the power supply is not functioning normally, repeat the installation and cabling procedures.
- On the external management device connected to the Routing
Engine, monitor the startup process to verify that the system has
booted properly.
Note If the system is completely powered off when you power on the power supply, the Routing Engine boots as the power supply completes its startup sequence. Normally, the router boots from the Junos OS on the CompactFlash card.
After turning on a power supply, wait at least 60 seconds before turning it off.
Complete the SCBE2-MX Upgrade

Upgrading an MX240, MX480, or MX960 Router to Use the SCBE3-MX
Upgrade the Routing Engine
If you are upgrading to the SCBE3-MX from an SCBE2-MX or older SCB, the Routing Engine must be upgraded to the first supported Junos release for the SCBE3-MX (18.4R1) before you install it in the SCBE3-MX. Also, we recommend that you update the recovery snapshot with the 18.4R1 or later image before you begin the upgrade. If the Routing Engine fails to boot from the primary image, it will attempt to boot from the recovery image. Since the older recovery image does not support the SCBE3-MX, the Routing Engine will crash if it attempts to boot from the old recovery image.
If you plug the Routing Engine into the SCBE3-MX without first upgrading Junos to 18.4R1 or later, Junos might crash and go to a db prompt. Should this occur, you’ll need to recover the router by copying the Junos software image for the 18.4R1 or later release and then booting from the USB drive to install 18.4R1 Junos on the SCBE3-MX. The USB install will wipe out the router configuration and all user files on the Routing Engine.
To upgrade the Routing Engine while it’s plugged into an SCBE2-MX or older SCB:
- Download the software related to your MX Series Routing Engine.
- If you have not already done so, connect to the console port on the switch from your management device, and log in to the Junos OS CLI.
- (Optional) Back up the current software configuration to a second storage option. See the Junos OS Installation and Upgrade Guide for instructions on performing this task.
- Install the new software.
- Reboot the Routing Engine and wait for it to boot with the new Routing Engine image.
- Install the SCBE3-MX into the Router Chassis. See:
