Upgrading an MX960 to Use the SCBE2-MX

date_range 06-May-21

arrow_backward

arrow_forward

Consider the following scenarios when upgrading an MX960 SCB-MX or SCBE-MX to use the SCBE2-MX:

Scenario 1: SCBE2-MX; Routing Engine with Junos OS Release 13.3R1 or later installed.

Replace the SCBs. Ensure you replace the Routing Engines at the same time.
Ensure that Enhanced IP or Enhanced Ethernet Network Services mode is configured before you power on the router.

Scenario 2: SCB-MX or SCBE-MX; existing Routing Engine with a Junos OS Release 13.3R1 or earlier installed.

Upgrade the Routing Engine (RE0 and RE1) software to Junos OS Release 13.3 or later.
Configure Enhanced IP or Enhanced Ethernet Network Services mode.
Replace the SCBs. Ensure that you replace the SCBs at the same time.

Scenario 3: Failed SCB-MX or SCBE-MX; Routing Engine with a Junos OS Release 13.3R1 or earlier installed.

Upgrade the software on the Routing Engine hosting the failed SCB-MX or SCBE-MX with Junos OS Release 13.3R1 or later.
Replace the SCBs. Ensure that you replace the SCBs at the same time.
Upgrade the software on the Routing Engine hosting the SCBE2-MX with Junos OS Release 13.3R1 or later.
Configure Enhanced IP or Enhanced Ethernet Network Services mode.

To upgrade the SCB-MX or SCBE-MX to SCBE2, perform the following steps:

Note:

You cannot upgrade to SCBE2-MX without powering off the MX960 router.

Prepare the MX960 Router for SCBE2-MX Upgrade

Verify that the system runs Junos OS Release 13.3 or later by issuing the show version command on the primary router.

content_copy zoom_out_map
user@host> show version
Model: mx960 
Junos Base OS Software Suite [13.3-yyyymmdd];
...

Note:

The SCBE2-MX is supported only on:

Junos OS Release 13.3 or later
Network Services Mode: Enhanced-IP

The latest software ensures a healthy system—that is, a system that comprises Routing Engines, control boards, and FPCs—before the upgrade.

For information about how to verify and upgrade the Junos OS, see the Junos OS Installation and Upgrade Guide.

Power Off the MX960 Router

Note:

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. The 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 MX960 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 MX960 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.
Carefully align the sides of the Routing Engine with the guides inside the opening on the SCBE2-MX.
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 MX960 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, or ETHERNET).
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 and DC OK LEDs light steadily, and the PS 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

Verify that the installation is successful and the SCBE2-MX is online by issuing the show chassis environment cb command:
```
user@host> show chassis environment cb 0
CB 0 status
State		Online
Temperature	30 degrees C / 86 degrees F
...
user@host> show chassis environment cb 1
CB 1 status
State		Online
Temperature	30 degrees C / 86 degrees F
...
```
Other details, such as, temperature, power, etc are also displayed along with the state.

Verify that the fabric planes come online correctly by issuing the show chassis fabric summary command:

content_copy zoom_out_map
user@host> show chassis fabric summary
Plane   State    Uptime
 0      Online   2 days, 19 hours, 10 minutes, 9 seconds
 1      Online   2 days, 19 hours, 10 minutes, 9 seconds
...

Verify that the backup Routing Engine is back online by issuing the show chassis routing-engine 1 command:
```
user@host> show chassis routing-engine 1
Routing Engine Status:
Slot 1:
Current State		Backup
...
```

Verify the SCBE2-MXs before you finish by issuing the show chassis hardware command:

content_copy zoom_out_map
user@host> show chassis hardware
Hardware inventory:
Item             Version  Part number  Serial number     Description
CB 0             REV 08   750-048307   CABC9829          Enhanced MX SCB 2
CB 1             REV 08   750-048307   CABC9828          Enhanced MX SCB 2
...

As shown in the example, the MX960 now has SCBE2-MXs.
