Replacing Host Subsystem Components on the SRX1400 Services Gateway

To replace subsystem components of the services gateway, you must power down the services gateway.

The following topics provide instructions on how to replace host subsystem components:

Replacing a Routing Engine on the SRX1400 Services Gateway

The Routing Engine is located in the front slot labeled RE0 on the services gateway. Before you replace the Routing Engine, you must power off the services gateway.

To replace the Routing Engine:

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. For more information about ESD, see Preventing Electrostatic Discharge Damage to the SRX1400 Services Gateway.
Disconnect any cables connected to the AUX or USB ports.
Loosen the captive screws at each end of the Routing Engine faceplate.
Pull open the ejector handles to unseat the Routing Engine as shown in Figure 37.

Grasp the Routing Engine by the ejector handles and slide it 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.
Carefully align the sides of the replacement Routing Engine with the guides inside the chassis.
Slide the Routing Engine into the slot until you feel resistance, and then press the Routing Engine faceplate until it engages the connectors.
Press both of the ejector handles inward to seat the Routing Engine. See Figure 38
Figure 38: Installing the Routing Engine on the SRX1400 Services Gateway
Tighten the captive screws on the left and right of the Routing Engine.
Reconnect cables previously attached to the AUX or USB ports.

Power on the services gateway by pressing the Power button on the front panel of the SYSIOC for three to five seconds if the Routing Engine does not start automatically. Wait for the device to start. The OK/FAIL LED on the Routing Engine faceplate should blink green, then light steadily.

Note: The Routing Engine might require several minutes to boot. If after this time the OK/FAIL LED is red, remove and reinstall the Routing Engine. If the OK/FAIL LED remains red, the Routing Engine is not functioning properly. Contact your customer support representative.

Note: The memory of the POWER button state is maintained in the Routing Engine.

If the Routing Engine is replaced, the state of the new Routing Engine determines whether the device powers up automatically or needs the power button to be pressed to power up.
If a device was powered down using the power button, and the Routing Engine was subsequently transferred to another device, the new device will power up only when the power button is pressed.

To check the status of the Routing Engine:

Figure 40: Installing an NSPC in the SRX1400 Services Gateway

Power on the services gateway, as described in “Powering On the SRX1400 Services Gateway”. The OK/FAIL LED on the NSPC faceplate should blink green, then light steadily.

Note: If the OK/FAIL LED is red, remove and reinstall the NSPC. If the OK/FAIL LED remains red, the NSPC is not functioning properly. Contact your customer support representative.

Warning: Never lift the services gateway using the handles on the front panels of the NSPC or other CFM cards. The handles might come off, causing the chassis to drop and inflicting possible grave injury.

Replacing an I/O Card on the SRX1400 Services Gateway

IOCs are installed in the services gateway in the slot labeled CFM2. SFPs and XFPs support hot-removable and hot-insertable functionality. Removing an SFP or XFP transceiver does not interrupt IOC functioning, but the removed transceiver no longer receives or transmits data.

Note: We strongly recommend the use of Juniper Networks SFP and XFP transceivers. We cannot guarantee correct operation if other transceivers are used. The transceiver type can be different in each port, as long as a Juniper Networks transceiver is used.

To replace an IOC:

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. For more information about ESD, see Preventing Electrostatic Discharge Damage to the SRX1400 Services Gateway.

Disconnect any cables connected to the Ethernet ports, marking them so they can be reconnected in the proper location. If the IOC uses fiber-optic cable, immediately cover each transceiver and the end of each cable with a rubber safety cap. Arrange the disconnected cables in the cable management system to prevent the cables from developing stress points.

Warning: Do not look directly into a fiber-optic transceiver or into the ends of fiber-optic cables. Fiber-optic transceivers and fiber-optic cable connected to a transceiver emit laser light that can damage your eyes.

Caution: Do not leave a fiber-optic transceiver uncovered except when inserting or removing cable. The safety cap keeps the port clean and prevents accidental exposure to laser light.

Caution: Avoid bending fiber-optic cable beyond its minimum bend radius. An arc smaller than a few inches in diameter can damage the cable and cause problems that are difficult to diagnose.

Loosen the captive screws at each end of the IOC faceplate.
Grasp the IOC by its handle and slide it halfway out of the chassis. See Figure 41.
Figure 41: Removing an I/O Card from the SRX1400 Services Gateway
Place one hand underneath the SPC to support it and slide it completely out of the chassis.
Place the IOC on the antistatic mat. If you are not reinstalling an IOC into the emptied slot within 30 minutes, install a blank panel over the slot to maintain proper airflow in the card cage.
If you need to replace the transceivers, see Replacing SFP and XFP Transceivers on I/O Cards on the SRX1400 Services Gateway; otherwise, continue with step 10.
Carefully align the sides of the replacement IOC with the guides inside the chassis.
Slide the IOC into the slot until you feel resistance, and then press the IOC faceplate until it engages the connectors.
Tighten the captive screws on the left and right of the IOC faceplate. See Figure 42.
Figure 42: Installing an IOC on the SRX1400 Services Gateway

If the IOC uses fiber-optic cable, remove the rubber safety cap from each transceiver and cable.

Insert the appropriate cables into the cable connector ports on each IOC.
Caution: Do not let fiber-optic cable hang free from the connector. Do not allow fastened loops of cable to dangle, which stresses the cable at the fastening point.
Caution: Avoid bending fiber-optic cable beyond its minimum bend radius. An arc smaller than a few inches in diameter can damage the cable and cause problems that are difficult to diagnose.

Power on the services gateway, as described in Powering On the SRX1400 Services Gateway. The OK/FAIL LED on the IOC faceplate should blink green, then light steadily.

Note: If the OK/FAIL LED is red, remove and reinstall the IOC. If the OK/FAIL LED remains red, the IOC is not functioning properly. Contact your customer support representative.

Warning: Never lift the services gateway using the handles on the front panels of the IOCs or other CFM cards. The handles might come off, causing the chassis to drop and inflicting possible grave injury.

Replacing a System I/O Card on the SRX1400 Services Gateway

The system I/O card (SYSIOC) is installed in the front of the SRX1400 Services Gateway.

To replace a SYSIOC:

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. For more information about ESD, see Preventing Electrostatic Discharge Damage to the SRX1400 Services Gateway.
Disconnect any cables attached to the console or management ports.
Loosen the captive screws at each end of the SYSIOC faceplate.
Pull open the ejector handles to unseat the SYSIOC.
Grasp the SYSIOC by the ejector handles and slide it halfway out of the chassis. See figure Figure 43

Power on the services gateway, as described in Powering On the SRX1400 Services Gateway.
The SYSIO LED on the SYSIOC faceplate should blink green, then light steadily.
Note: If the SYSIO LED is red, remove and reinstall the SYSIOC. If the SYSIO LED remains red, the SYSIOC is not functioning properly. Contact your customer support representative.
Check the status of the SYSIOC by using the show chassis environment fpc 0 command.

Caution: Do not let fiber-optic cable hang free from the connector. Do not allow fastened loops of cable to dangle, which stresses the cable at the fastening point.

Caution: Avoid bending fiber-optic cable beyond its minimum bend radius. An arc smaller than a few inches in diameter can damage the cable and cause problems that are difficult to diagnose.

Replacing SFP and XFP Transceivers on I/O Cards on the SRX1400 Services Gateway

The small form-factor pluggable transceivers (SFPs) and XFPs are optical transceivers that are installed in IOC. SFPs and XFPs are hot-insertable and hot-removable. Removing an SFP or XFP does not interrupt IOC functioning, but the removed SFP or XFP no longer receives or transmits data.

To replace an SFP or XFP transceiver:

Have ready a replacement transceiver or a transceiver slot plug, an antistatic mat, and a rubber safety cap for the transceiver.
Attach an electrostatic discharge (ESD) grounding strap to your bare wrist and connect the strap to one of the ESD points on the chassis.
Label the cables connected to the transceiver so that you can reconnect them correctly later.
Warning: Do not look directly into a fiber-optic transceiver or into the end of a fiber-optic cable. Fiber-optic transceivers contain laser light sources that can damage your eyes.
Remove the cable connector plugged into the transceiver.
Carefully drape the disconnected cables to prevent the cable from developing stress points.
Caution: Avoid bending fiber-optic cable beyond its minimum bend radius. An arc smaller than a few inches in diameter can damage the cable and cause problems that are difficult to diagnose.
Pull the ejector handle out from the transceiver to unlock the transceiver.
Caution: Make sure that you open the ejector handle completely until you hear it click. This prevents damage to the transceiver.
Use needlenose pliers to pull the ejector handle out from the SFP.
Grasp the transceiver ejector handle and pull the transceiver approximately 0.5 in. (1.3 cm) out of the IOC.
Using your fingers, grasp the body of the transceiver and pull it the rest of the way out of the IOC.
