[. . . ] Remove the chassis rear component cover by loosening the screws on the corners of the cover and pulling it straight out from the chassis. Remove the SFM, as described in the M40e and M160 router hardware guides. Take the SFM offline by doing one of the following: ! Use the following CLI command: user@host> request chassis sfm slot slot-number offline ! Press and hold the offline button on the SFM faceplate at the rear of the router until the SFM OK LED turns off (about 5 seconds). 4. Replace the SFM with one that you know works. Bring the SFM online by doing one of the following: ! Use the following CLI command: user@host> request chassis sfm slot slot-number online ! Press and hold the offline button on the SFM faceplate until the green OK LED lights (about 5 seconds). 6. Reinstall the rear component cover and tighten the screws to secure it to the chassis. See "Display the SFM Summary Status" on page 349. 356 ! Verifying SFM Failure Chapter 26: Monitoring the SFMs Getting SFM Hardware Information Steps To Take To get the hardware information you need to return a failed SFM, follow these steps: 1. Display SFM Hardware Information on page 357 2. Locate the SFM Serial Number ID Label on page 357 Step 1: Display SFM Hardware Information Action To display the SFM hardware information, use the following CLI command: user@host> show chassis hardware Sample Output user@host> show chassis hardware Item Version Part number Chassis [. . .

Step 2: Locate the SFM Serial Number ID Label Action To locate the SFM serial number ID label, look on the left side of the SFM top panel (see Figure 147). Figure 147: SFM Serial Number ID Label Serial number ID label 1618 Getting SFM Hardware Information ! 357 JUNOS Internet Software Network Operations Guide: Hardware Replacing the SFM The SFMs are hot-removable and hot-insertable. You can remove and replace SFMs without powering down the router or disrupting the routing functions. However, you must take an SFM offline before replacing it. Inserting or removing an SFM causes a brief interruption in forwarding performance (about 500 ms) as the Packet Forwarding Engine reconfigures the distribution of packets across the remaining SFMs. Action To replace an SFM, see "Return the Failed Component" on page 86, or the procedure to return a field-replaceable unit in the M40e or M160 router hardware guide. 358 ! Replacing the SFM Chapter 27 Monitoring the MCS You monitor and maintain the Miscellaneous Control Subsystem (MCS) to provide control and monitoring functions for router components and to provide SONET/SDH clocking for the M40e and M160 routers. (See Table 86. ) Table 86: Checklist for Monitoring the MCS Monitor MCS Tasks Understanding the MCS on page 360 Checking the MCS Status on page 362 1. Check the MCS Environmental Status on page 362 show chassis environment mcs Command or Action 2. Check the MCS Status from the Craft Interface on page 363 show chassis craft-interface 3. Check the MCS LEDs on page 364 Check the LEDs on the MCS faceplate. Verifying MCS Failure on page 365 1. Check the MCS Fuses on page 365 The M40e and M160 router fuses are located in a fuse box at the rear of the midplane, behind the lower rear impeller assembly. Remove the MCS and replace it with one that you know works. 2. Perform an MCS Swap Test on page 366 Getting MCS Hardware Information on page 367 1. Display the MCS Hardware Information on page 367 2. Locate the MCS Serial Number ID Label on page 368 show chassis hardware Look at the bottom left of the MCS board. See "Return the Failed Component" on page 86, or follow the procedure in the M40e or M160 router hardware guide. Returning the MCS on page 368 ! 359 JUNOS Internet Software Network Operations Guide: Hardware Understanding the MCS Purpose Inspect the MCS to ensure that control and monitoring functions for router components and SONET/SDH clocking for the router function normally.
