MX10003 Chassis

MX10003 Chassis Description

The router chassis is a rigid sheet metal structure that houses all the other router components. Figure 1 shows the front of the fully configured chassis. The chassis measures 5.21 in. (13.23 cm) high, 17.6 in. (44.7 cm) wide, and 30 in. (76.2 cm) deep. The chassis installs in standard 800-mm or 900-mm deep open rack, 19-in. equipment racks, or telco open-frame racks. The total weight of a fully loaded router: up to 157.4 lb (71.4 kg) for an AC-powered chassis, and up to 163.4 lb (74.1 kg) for a DC-powered chassis. For more information, see MX10003 Router Physical Specifications.

CAUTION:

Before removing or installing components, attach an ESD strap to an ESD point, and place the other end of the strap around your bare wrist. Failure to use an ESD strap could result in damage to the hardware components.

MX10003 Front and Rear Panel Components

The front panel on the front of the router enables you to view status and troubleshooting information at a glance. The front panel contains LEDs for the router components, online/offline and reset buttons, auxiliary and console ports, clocking ports, and ports for the 10-Gigabit Ethernet MIC.

MX10003 Cable Management Bracket Description

The cable management bracket (see Figure 5) consists of dividers and installs on the front of the chassis. The cable management bracket enables you to route the cables outside the router and away from the RCBs, MICs, and MPCs.

Figure 5: Cable Management Bracket

The air filter unit is installed on the cable management brackets. Before installing the air filter unit, ensure that the cable management brackets are already installed on the front of the router. Figure 6 shows the air filter unit along with the cable management brackets installed on the router.

Alarm LEDs on the MX10003 Front Panel

One alarm LED located on the front panel of the RCB. A red light indicates a critical condition that can result in a system shutdown, and a yellow light indicates a less severe condition that requires monitoring or maintenance.

Table 3 describes the alarm LED in more detail.

Note:

Only the primary RCB drives the LED to show the status of the chassis.

Table 3: Alarm LEDs on the MX10003 Front Panel
Color	State	Description
Red	On steadily	Major alarm—Indicates a critical condition that can cause the router to stop functioning. Possible causes include component removal, failure, or overheating.
Yellow	On steadily	Minor alarm—Indicates a serious but nonfatal error condition, such as a maintenance alert or a significant increase in component temperature.
Red	Blinking	Both major and minor alarms—Indicates that both major and minor alarm conditions are present.
-	Off	No alarms are present.
