Juniper Networks M10i manual Removing a PIC, Services Command Reference

Chapter 13: Replacing Hardware Components

PICs are hot-removable and hot-insertable. A removed PIC no longer receives or transmits data, and removing or inserting a PIC briefly interrupts forwarding of traffic through the remaining PICs.

To replace a PIC, perform the following procedures:

■Removing a PIC on page 97

■Installing a PIC on page 99

Removing a PIC

To remove a PIC, follow this procedure (see Figure 35):

1.Place an electrostatic bag or antistatic mat on a flat, stable surface to receive the PIC. If the PIC connects to fiber-optic cable, have ready a rubber safety cap for each transceiver and cable.

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. Make sure the router is attached to a proper earth ground. For more information about ESD, see “Preventing Electrostatic Discharge Damage” on page 140.

3.If the PIC has multiple cable connector ports, label the cable connected to each port, to make it easier to reconnect the cables correctly.

4.Use one of the following methods to take the PIC offline:

■Press and hold the PIC offline button until its failure indicator LED lights, which usually takes about 5 seconds. The failure LED is usually red; for more information, see the M10i Internet Router PIC Guide. The offline button for each PIC is located on the HCM and is labeled with the PIC slot number. The PICs in FPC 0 are located on the upper HCM, and the PICs installed in FPC 1 are located on the lower HCM.

■Issue the following CLI command:

user@host>request chassis pic fpc-slot fpc-slotpic-slot pic-slotoffline

For more information about the command, see the JUNOS System Basics and

Services Command Reference.

5.Disconnect the cables from the PIC. If the PIC uses fiber-optic cable, immediately cover each transceiver and the end of each cable with a rubber safety cap.

WARNING: Do not look directly into the ends of fiber-optic cables or into the transceivers on the interface faceplate. Single-mode fiber-optic cable and the interfaces
