MX10004 Chassis
Learn about the MX10004 router chassis, the field replaceable units (FRUs), and the physical specifications of each component.
MX10004 Chassis Physical Specifications
The MX10004 modular chassis is a rigid sheet-metal structure that houses the other router components. You can mount up to six MX10004 routers in a standard 19-in. 4-post rack (42 U), provided that the rack can bear the combined weight and that adequate power and cooling is available. See Figure 1 to help identify the major components. See Table 1 for the physical specifications of the chassis of these components.

1 — RCBs | 3 — Line cards |
2 — Status panel |
The handles on each side of the chassis are not for lifting the chassis. These handles facilitate the fine-tune positioning of the chassis on the base brackets. Do not use the handles to lift the chassis, even when the chassis is empty. See Mount the Juniper Networks MX10004 Router Using the JNP10004-RMK-4POST Rack-Mount Kit or Mount the Juniper Networks MX10004 Router Using the JNP10K-RMK-4PST-XT Rack-Mount Kit for instructions about properly moving a loaded chassis.

MX10004 Field-Replaceable Units
Field-replaceable units (FRUs) are router components that you can replace at your site. The router uses the following types of FRUs:
Hot-insertable and hot-removable—You can remove and replace these components without powering off the router or disrupting the routing function.
Hot-pluggable—You can remove and replace these components without powering off the router, but the routing function is interrupted until you replace the component.
Table 2 lists the FRUs and their types for the MX10004 routers.
FRU | Type |
---|---|
Power supplies | Hot-insertable and hot-removable. |
Fan trays | Hot-insertable and hot-removable. |
Fan tray controllers | Hot-insertable and hot-removable. |
Routing and Control Boards (RCBs) | Redundant configuration:
Base configuration: Removal of the RCB causes the router to shut down. To prevent traffic disruption, take the chassis offline. If a temporary disruption is acceptable, you can install a replacement RCB in the second slot. The system restarts to elect a primary RCB and a backup RCBs If necessary, you can manually switch the primary and backup RCB using the |
Switch Fabric Boards (SFBs) | SFBs are hot-insertable and hot-removable. We recommend that you take SFBs offline before removing them to avoid traffic loss while the router fabric is being reconfigured. Use the following command: request chassis sfb slot slot-number offline |
Line cards | Hot-insertable. We recommend that you take line cards offline before removing them. Use the following command: request chassis fpc slot slot-number offline |
Optical transceivers | Hot-insertable and hot-removable. |
Line cards are not part of the base or redundant configuration. You must order them separately.
If you have a Juniper Care service contract, register any addition, change, or upgrade of hardware components at https://www.juniper.net/customers/support/tools/updateinstallbase/. Failure to do so can result in significant delays if you need replacement parts. This note does not apply if you replace an existing component with the same type of component.
MX10004 Status Panel
The MX10004 status panel shows the overall status of the chassis.
The MX10004 chassis ships with an enhanced power bus to future-proof the chassis for potential power growth.
The status panel indicates the chassis status through a set of five bicolor LEDs. It has an Azure blue stripe along the left side of the LEDs. See Figure 2 for a chassis status panel.

Table 3 describes the status panel LEDs.
