MX10008 Chassis

 

MX10008 Chassis Physical Specifications

The MX10008 modular chassis is a rigid sheet-metal structure that houses the other router components. You can mount up to three MX10008 routers in a standard 19-in. 4-post rack (42 U) rack provided the rack can handle the combined weight and there is adequate power and cooling. Table 1 summarizes the physical specifications of the chassis. See Figure 1.

Warning

The handles on each side of the chassis facilitate the fine-tune positioning of the chassis on the mounting brackets. Do not use the handles to lift the chassis, even when the chassis is empty. See Mounting an MX10008 in a 4-Post Rack Using a Mechanical Lift or Manually Mounting an MX10008 in a 4-Post Rack for instructions for properly moving a loaded chassis.

Field-Replaceable Units in an MX10008

Field-replaceable units (FRUs) are router components that you can replace at your site. Routers use these 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 MX10008 routers.

Table 2: FRUs in an MX10008 Router

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 Board (RCB)

Redundant configuration:

  • Master RCB is hot-pluggable.

  • Backup RCB is hot-insertable and hot-removable.

Base configuration:

  • Removal of the RCB causes the router to shut down. You can install a replacement RCB in the second slot. The system restarts to select a master and backup. If necessary, you can switch the master and backup using the request chassis routing-engine master switch command.

See MX10008 Components and Configurations.

Switch Fabric Boards (SFBs)

Hot-insertable and hot-removable.

We recommend that you take the SFBs offline before removing them to avoid traffic loss while the router fabric is being reconfigured. You can take SFBs offline by using the request chassis sib (offline | online) slot slot-number command.

Line cards

Hot-insertable and hot-removable.

We recommend that you take line cards offline before removing them. You can take line cards offline by using the request chassis fpc slot slot-number offline command.

Note: Line cards are not part of the base configuration or redundant configuration. You must order them separately.

Optical transceivers

Hot-insertable and hot-removable.

See MX10008 Optical Transceiver and Cable Support for the Junos OS release in which the transceivers were introduced.

Note

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.

MX10008 Status Panel LEDs

The status panel of the MX10008 routers has two purposes:

  • Shows the overall status of the chassis

  • Indicates the type of power bus internal to the chassis

Some chassis ship with an enhanced power bus to support the power needs of higher wattage line cards.

The status panel indicates chassis status through a set of five bi-color LEDs. See Figure 2 for a chassis status panel with the standard power bus.

Figure 2: Status Panel on the Chassis with the Standard Power Bus

Chassis with enhanced power bus has the same set of five bi-color LEDs, but also have an azure blue line to indicate the enhanced power bus (see Figure 3).

Alarms

Red

On steadily

Major (red)—Indicates a critical situation on the device that has resulted from one of the following conditions. A red alarm condition requires immediate action.

  • One or more hardware components have failed.

  • One or more hardware components have exceeded temperature thresholds.

  • An alarm condition configured on an interface has triggered a critical warning.

Yellow

On steadily

Minor (yellow or amber)—Indicates a noncritical condition on the device that, if left unchecked, might cause an interruption in service or degradation in performance. A yellow alarm condition requires monitoring or maintenance. For example, a missing rescue configuration generates a yellow system alarm.

MX10008 Optional Equipment

The MX10008 router supports the cable management system as an optional equipment.

The cable management system (see Figure 4) enables you to route optical cables away from the line card ports for better airflow through the chassis. Using this optional system also makes it easier to use cable ties or strips to organize the cabling.

Figure 4: Cable Management System
 Cable Management System

The cable management system comprises a set of handle extensions and a tray that snaps to the extensions (see Figure 5) for an individual line card. The handle extensions can be used with or without the cable tray. It is not necessary to remove the handle extensions if you want to remove a line card.

Cables are draped across or under the handle extensions and then secured with cable wraps (see Figure 6).
