Install and Remove PTX10008 Power System Components
PTX10008 routers support both AC, DC, high voltage alternating current (HVAC), and high voltage direct current (HVDC) power supplies. To install and remove the power supplies in a PTX10008 router, read the following sections. All power supply models are hot-insertable and hot-removeable field-replaceable units (FRUs). You can install up to six power supplies in the rear of the chassis in the slots provided along the left side.
If you are upgrading a JNP10008-SF fabric system to use JNP10K-PWR-AC2 power supplies, also upgrade your fans and fan tray controllers to ensure the proper airflow. JNP10K-PWR-AC2 power supplies require JNP10008-FAN2 and JNP10008-FTC2 cooling systems.
Use the same type of power supply in all slots. Do not mix power supply models in the same chassis.
See the heat symbol .
Wear heat-resistant hand gloves while accessing the fan tray and power
supply.
Install a JNP10K-PWR-AC Power Supply
Before you install a JNP10K-PWR-AC power supply in the router:
Ensure that you understand how to prevent ESD damage. See Prevention of Electrostatic Discharge Damage.
If the AC power source outlets have a power router, set them to the off (O) position.
Ensure that you have the following parts and tools available to install a JNP10K-PWR-AC power supply:
Electrostatic discharge (ESD) grounding strap
Phillips (+) screwdriver, number 1
Power cords appropriate for your geographical location. See PTX10008 Power Cables Specifications.

Replacement power supply or a cover for the power supply slot
CAUTION:Do not leave the power supply slot empty for a long time while the router is operational. Either replace the power supply promptly or install a cover over the empty slot.
Before you remove a power supply, ensure that you have power supplies sufficient to power the router left in the chassis. See PTX10008 Power Planning for JNP10008-SF3 Switch Fabric or PTX10008 Power Planning for JNP10008-SF Switch Fabric.
To remove a JNP10K-PWR-AC power supply from a PTX10008 router:
Install a JNP10K-PWR-AC2 Power Supply
Use the same type of power supply in all slots. Do not mix power supply models in a production chassis. The only time you are allowed to have two models concurrently running in a system is when you are in the process of swapping out all JNP10K-PWR-AC power supplies with all JNP10K-PWR-AC2 power supplies.
Protect yourself from severe burns by wearing heat-protective gloves when removing a running JNP10K-PWR-AC2 power supply from the chassis. The power supply can reach temperatures between 158°F and 176°F (70°C to 80°C) under running conditions.
Before you install a JNP10K-PWR-AC2 power supply in the chassis:
Ensure that you have followed all safety warnings and cautions.
Ensure that you understand how to prevent ESD damage. See Prevention of Electrostatic Discharge Damage.
If the AC or DC power source outlets have a power switch, set them to off (O). Ensure that you have the following parts and tools available to install a JNP10K-PWR-AC2 power supply:
Electrostatic discharge (ESD) grounding strap
Phillips (+) screwdriver, number 1
Power cables appropriate for your geographical location (for low-voltage installations) or input amperage (for high-voltage installations). See PTX10008 Power Cables Specifications. HVAC and HVDC connectors and lugs must be installed by a qualified electrician before installation.

To remove a JNP10K-PWR-AC2 power supply from a PTX10008 router:
Install a JNP10K-PWR-DC Power Supply
Before you install a JNP10K-PWR-DC power supply in the chassis:
Ensure that you have followed all safety warnings and cautions:
Warning:Before you perform DC power procedures, ensure there is no power to the DC circuit. To ensure that all power is off, locate the circuit breaker on the panel board that services the DC circuit, switch the circuit breaker to the off position, and tape the switch handle of the circuit breaker in the off position.
CAUTION:Before you connect power to the router, a licensed electrician must attach a cable lug to the grounding and power cables that you supply. A cable with an incorrectly attached lug can damage the router (for example, by causing a short circuit).
CAUTION:Do not mix AC and DC power supplies in the same chassis.
CAUTION:To meet safety and electromagnetic interference (EMI) requirements and to ensure proper operation, you must connect PTX10008 routers to earth ground before you connect them to power. For installations that require a separate grounding conductor to the chassis, use the protective earthing terminal on the router chassis to connect to earth ground. For instructions on connecting a PTX10008 router to ground using a separate grounding conductor, see Connect the PTX10008 Router to Earth Ground.
Note:The battery returns of the JNP10K-PWR-DC power supply must be connected as an isolated DC return (DC-I).
Ensure that you understand how to prevent ESD damage. See Prevention of Electrostatic Discharge Damage.
Ensure that you have the following parts and tools available to install a JNP10K-PWR-DC power supply:
Electrostatic discharge (ESD) grounding strap
DC power source cables (not provided) with the cable lugs (provided) attached.
The provided Panduit LCD4-14A-L, or equivalent, terminal lugs in a PTX10008 are sized for either 4 AWG (21.1 mm2) or 6 AWG (13.3 mm2) power source cables. When using all JNP10K-PWR-DC power supply modules in the chassis, the DC power source cables that you provide must be 6 AWG (13.3 mm²) stranded wire. We recommend that you install heat-shrink tubing insulation around the crimped section of the power cables and lugs.
Note:If you upgrade the JNP10K-PWR-DC to a JNP10K-PWR-DC2 and set the input mode to high (80 A), you must use 4 AWG (21.1 mm²) stranded wire. The 4 AWG (21.1 mm²) stranded wire should be rated 75° C, or per local electrical code.
Note:See the heat symbol
