[. . . ] For more information about the causes of alarms, see "M40e Chassis and Interface Alarm Messages" on page 147. FPC--For each of the FPC slots in the router, there are two LEDs and an offline button located on the craft interface directly above the slot. The green LED labeled OK and the red LED labeled FAIL indicate FPC status. For more information, see "FPC LEDs and Controls on the M40e Craft Interface" on page 38. Host module--Two sets of LEDs at the upper right corner of the craft interface indicate the status of the two host modules. Each set includes three LEDs--a green one labeled MASTER, another green one labeled ONLINE, and a red one labeled OFFLINE.

To view a more detailed description of the alarm cause, issue the show chassis alarms CLI command: user@host> show chassis alarms There are two classes of alarm messages: · Chassis alarms--Indicate a problem with a chassis component such as the cooling system or power supplies, as described in Table 18 on page 148. Interface alarms--Indicate a problem with a specific network interface, as described in Table 19 on page 148. · In both Table 18 on page 148 and Table 19 on page 148, the text in the column labeled "LCD Message" appears in the LCD. The text in the column labeled "CLI Message" appears in the output from the show chassis alarms command.

Figure 77 on page 150 shows the location in the fuse box of the fuse for each component. The labels shown in the figure do not appear on the actual fuses (the clear cover on every fuse reads BUSS GMT-X), but a table on the surface of the midplane below the fuse box displays the same information. Copyright © 2010, Juniper Networks, Inc. 149 M40e Multiservice Edge Router Hardware Guide Figure 77: Fuse Locations in the Fuse Box When a fuse has blown but the power supplies are still delivering power to router, the yellow LED adjacent to the fuse lights. For vertically oriented fuses (in the groups labeled J241 through J244 in Figure 77 on page 150), the LED is located below the fuse; for horizontally oriented fuses (in the group labeled J240), it is to the left of the fuse. NOTE: The LEDs are each about 0. 1in. They might be difficult to see when not lit. A blown fuse can cause a component to fail even though it is correctly installed and the power supplies are functioning.
