Connecting the MX10008 to Power
The MX10008 router support both AC and DC power supplies. Additionally, MX10008 routers also support high-voltage alternating current (HVAC) and high-voltage direct current (HVDC) power supplies. To connect power to a MX10008 router, refer to the following procedures:
Do not mix power supply models in the same chassis in a running environment. DC and HVDC can coexist in the same chassis during the hot swap of DC for HVDC.
Connect the MX10008 to Earth Ground
To meet safety and electromagnetic interference (EMI) requirements and to ensure proper operation, you must connect the chassis to earth ground before you connect it to power.
You must install the MX10008 in a restricted-access location and ensure that the chassis is always properly grounded. The MX10008 has a two-hole protective grounding terminal provided on the chassis. See Figure 2. Under all circumstances, use this grounding connection to ground the chassis. For AC-powered systems, you must also use the grounding wire in the AC power cord along with the two-hole grounding lug connection. This tested system meets or exceeds all applicable EMC regulatory requirements with the two-hole protective grounding terminal.
Before you connect earth ground to the protective earthing terminal of an MX10008, ensure that a licensed electrician has attached an appropriate grounding lug to the grounding cable. Using a grounding cable with an incorrectly attached lug can damage the router.
Mount your router in the rack before attaching the grounding lug to the router. See Installing the MX10008 into a Rack.
Ensure that you have the following parts and tools available:
An electrostatic discharge (ESD) grounding strap (provided).
Protective earthing terminal lug (provided).
Grounding cable for your MX10008 (not provided)—The grounding cable must be 6 AWG (13.3 mm²), minimum 90° C wire, or as permitted by the local code.
Grounding lug for your grounding cable (provided)—This bracket attaches to the lower left corner of the MX10008 router chassis next to PSU 5, providing a protective earthing terminal for the router. The grounding lug required is a Panduit LCD6-10A-L or equivalent.
A Phillips screwdriver to tighten the two screws that are mounted on the chassis.
An AC-powered MX10008 gains additional grounding when you plug the power supply in the router into a grounded AC power outlet by using an AC power cord appropriate for your geographical location. See MX10008 Power Cables Specifications.
To connect earth ground to an MX10008 chassis:
- Verify that a licensed electrician has attached the cable lug (provided in the accessory kit) to the grounding cable.
- Connect the other end of the grounding cable to a proper earth ground, such as the rack in which the router is mounted.
- Attach an ESD grounding strap to your bare wrist, and
connect the strap to the ESD grounding point next to the earthing
posts (see Figure 1).
Figure 1: ESD Point for the MX100081—Grounding point
- Remove the two screws on the chassis using a Phillips screwdriver.
- Place the chassis grounding lug and cable over the PEM nuts with the cable connection pointing to the left. See Figure 2.
- Place the two screws over the grounding lug and grounding cable.
- Tighten the two 10-32 screws using a Phillips screwdriver applying torque between of 30.1 in.-lb (3.4 N-m) and 42.04 in.-lb (4.75 N-m).
- Dress the grounding cable and ensure that it does not touch or block access to other device components and that it does not drape where people could trip over it.
Connect AC Power to an MX10008
After you ground the chassis, connect the power supplies, and supply power to the chassis, the system initiates the power-on sequence. This sequence can start incrementally with a single power supply, but it is not recommended that you bring up an MX10008 system with at less than three power supplies.
Before you begin to connect power to the router, be sure you understand how to prevent ESD damage. See Prevention of Electrostatic Discharge Damage.
To connect AC power to an MX10008 chassis:
- Connect the chassis to earth ground (see Connect the MX10008 to Earth Ground).
To meet safety and electromagnetic interference (EMI) requirements and to ensure proper operation, an MX10008 must be adequately grounded before it is connected to power.
For installations that require a separate grounding conductor to the chassis, use the protective earthing terminal on the rear panel of the MX10008 to connect to the earth ground.
An MX10008 gets additional grounding when you plug the power supply in the router into a grounded AC power outlet by using the AC power cord appropriate for your geographical location. See MX10008 Power Cables Specifications.
- Install power supplies in the router and apply power. See How to Install a JNP10K-PWR-AC Power Supply or How to Install a JNP10K-PWR-AC2 Power Supply.
Connect DC Power to an MX10008
The overall process of bringing up a DC-powered chassis involves the proper cabling of the individual power supplies, adding the power supplies to the chassis, and supplying power. The power-on sequence can start incrementally with a single power supply, we recommended that you bring up an MX10008 system with at least three power supplies.
Each power supply input feed must be connected to a dedicated DC power source outlet.
Before you begin connecting power to the router, be sure you understand how to prevent electrostatic discharge (ESD) damage. See Prevention of Electrostatic Discharge Damage.
