If both power supplies have failed, the system temperature might have exceeded the threshold, causing the system to shut down. See "Troubleshooting the M7i Power System When the LEDs on All M7i Power Supplies Are Blinking or Off" on page 81. If the fan tray has failed, it must be replaced for the router to operate normally.

Replacing most FRUs requires minimal router downtime. The router uses the following types of FRUs: · Hot-removable and hot-insertable FRUs--You can remove and replace these components without powering down the router or disrupting the routing functions. Hot-pluggable FRUs--You can remove and replace these components without powering down the router, but the routing functions of the system are interrupted when the component is removed. · Table 14 on page 85 lists the FRUs for the M7i router.

Upgrading or downgrading a CFEB device requires a system reboot, as described in 86 Copyright © 2010, Juniper Networks, Inc. Chapter 15: Replacing M7i Hardware Components "Upgrading and Downgrading the CFEB and CFEB-E" on page 88. To replace the CFEB or CFEB-E, perform the following procedures: · · · Removing the M7i CFEB and CFEB-E on page 87 Installing the M7i CFEB and CFEB-E on page 88 Upgrading and Downgrading the CFEB and CFEB-E on page 88 Removing the M7i CFEB and CFEB-E To remove the CFEB or CFEB-E (see Figure 32 on page 87): 1. Place an electrostatic bag or antistatic mat on a flat, stable surface. 2. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis. 3. Press and hold the ONLINE/OFFLINE button on the faceplate of the CFEB or CFEB-E until the green OK LED turns off, which takes about 5 seconds. 4. Loosen the thumbscrew on each ejector locking tab (shown in Figure 4 on page 10), using a Phillips screwdriver if necessary. 5. Pull the ends of the ejector handles outward until they are nearly perpendicular to the faceplate of the CFEB or CFEB-E. 6. Grasp the ejector handles and pull firmly to slide the CFEB or CFEB-E about halfway out of the chassis. 7. Place one hand under the CFEB or CFEB-E to support it, slide it completely out of the chassis, and place it on the antistatic mat or in the electrostatic bag. CAUTION: When a CFEB or CFEB-E is out of the chassis, do not hold it by the ejector handles. Do not stack CFEBs or CFEB-Es on top of or under other components. Place each one individually in an electrostatic bag or on its own antistatic mat on a flat, stable surface. Figure 32: Removing the CFEB or CFEB-E Copyright © 2010, Juniper Networks, Inc. 87 M7i Multiservice Edge Router Hardware Guide Installing the M7i CFEB and CFEB-E To install the CFEB or CFEB-E (see Figure 33 on page 88): 1. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis. 2. Verify that the ends of the ejector handles are pulled outward to a position nearly perpendicular to the faceplate of the CFEB or CFEB-E. 3. Place one hand under the CFEB or CFEB-E to support it and grasp one of the ejector handles at the front with the other hand. 4. Align the rear of the CFEB or CFEB-E with the guides inside the chassis and slide it in completely. 5. [. . . ] If you do not have these materials, contact your Juniper Networks representative about approved packaging materials. 2. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist and connect the strap to one of the ESD points on the chassis. Verify that the router is attached to a proper earth ground. 3. See "Powering Off the M7i Router" on page 60. [. . . ]
