Installing Power Supplies - HP FlexNetwork HSR6800 Installation Manual

IMPORTANT:
• The resistance reading should be smaller than 5 ohms between the chassis and the ground.
• To guarantee the grounding effect, use the grounding cable provided with the router to connect to
the grounding strip in the equipment room.
To connect the grounding cable:

1.
Attach the two grounding screws to the two-hole lug end of the grounding cable.

Installing power supplies

The HSR6802 and HSR6804 routers each provide two power supply slots. An HSR6808 router
provides four power supply slots. Slots except the Slot 1 (PWR1) are provided with filler panels. The
routers support both AC (PSR650-A and PSR1200-A) and DC (PSR650-D and PSR1200-D) power
supplies, but AC and DC power supplies cannot work together. The power supplies in use must be of
the same specification.
Before you install a power supply, make sure the power switch is off and the grounding cable is
reliably grounded.
The procedures for installing power supplies are the same. This section uses a PSR650-A as an
example.
To install a power supply:
Face the front of the router and locate the slot to be used.
1.
Loosen the captive screws with a Phillips screwdriver to remove the filler panel from the slot.
2.
Keep the removed filler panel for future use.
Skip this step if you install the power supply in the PWR1 slot.
Holding the handle of the power supply with one hand and supporting the bottom of the power

supply with the other hand, insert the power supply slowly along the slide rails until it makes
close contact with the backplane.
Use a Phillips screwdriver to fasten the captive screws on the two sides of the power supply.
