Remove a JNP10K-PWR-DC2 Power Supply
Before you remove a DC power supply from the router:
• Review how to prevent ESD damage. See "Prevention of Electrostatic Discharge Damage" on page
263 .
• Ensure that you have the following parts and tools available to remove a JNP10K-PWR-DC2 power
supply:
• Heat-protective gloves that can withstand temperatures from 158° F to 176° F (70° C to 80° C)
• Electrostatic discharge (ESD) grounding strap
• Phillips (+) screwdriver, numbers 1 and 2
• 13/32 in. (10 mm) nut driver or socket wrench
• Replacement power supply or a cover for the power supply slot
CAUTION: A working JNP10K-PWR-DC2 power supply can reach temperatures of
158° F to 176° F (70° C to 80° C) under running conditions. In order to avoid injury, do
not touch a running power supply with your bare hands.
CAUTION: Before you remove a power supply, ensure that you have power supplies
sufficient to power the router left in the chassis. See
"MX10004 Power Planning" on
page 88 and "Power Requirements for MX10004 Components" on page 88 .
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.
To remove a JNP10K-PWR-DC2 power supply from an MX10004 router:
1. Wrap and fasten one end of the ESD grounding strap around your bare wrist and connect the other
end of the strap to an ESD point on the chassis. An ESD point is located next to the protective
earthing terminal and below PSU 5 on the rear of the MX10004 (see
Figure 57 on page 149 ).
