Figure 10 Connecting the grounding cable to the grounding hole of router
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 as long as possible.
Installing a power supply
CAUTION:
•
Do not install AC and DC power supplies on the same router.
•
Power supplies on a router must be the same model.
Each of an HSR6802 and an HSR6804 router provides 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
Before you install the 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:
1.
Face the front of the router and locate the slot to be used.
2.
Loosen the captive screws with a Phillips screwdriver to remove the filler panel from the slot.
Keep the removed filler panel for future use.
Skip this step if you install the power supply to the PWR1 slot.
3.
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.
4.
Use a Phillips screwdriver to fasten the captive screws on the two sides of the power supply.
