GRF 400/1600 Getting Started - 1.4 Update 2
v
Important safety instructions
The following safety instructions apply to the GRF router models GRF-4-AC, GRF-4-DC,
GRF-16-AC, and GRF-16-DC except as noted:
1
Read and follow all warning notices and instructions marked on the product or included in
the manual.
2
Do not attempt to service this product yourself, as opening or removing covers and/or
components may expose you to dangerous high voltage points or other risks. Refer all
servicing to qualified service personnel.
3
The maximum recommended ambient temperature for all GRF router models is 104˚
Fahrenheit (40˚ Celsius). Care should be given to allow sufficient air circulation or space
between units when the GRF chassis is installed in a closed or multi-unit rack assembly
because the operating ambient temperature of the rack environment might be greater than
room ambient.
4
Slots and openings in the GRF cabinet are provided for ventilation. To ensure reliable
operation of the product and to protect it from overheating, maintain a minimum of 4
inches clearance on the top and sides of the GRF 400 router, and a minimum of 6 inches
on the top and sides of the GRF 1600 router.
5
Installation of the GRF 400 or 1600 in a rack without sufficient air flow can be unsafe.
6
If a GRF router is installed in a rack, the rack should safely support the combined weight
of all equipment it supports.
- A fully loaded, redundant-power GRF 400 weighs 38.5 lbs (17.3 kg).
- A fully loaded, single-power GRF 400 weighs 32.5 lbs (14.6 kg).
- A four card, redundant-power GRF 1600 weighs 147 lbs (66.2 kg).
- A four card, single-power GRF 1600 weighs 127 lbs (57.2 kg).
7
The connections and equipment that supply power to GRF routers should be capable of
operating safely with the maximum power requirements of the particular GRF model. In
the event of a power overload, the supply circuits and supply wiring should not become
hazardous.
8
Models with AC power inputs are intended to be used with a three-wire grounding type
plug - a plug which has a grounding pin. This is a safety feature. Equipment grounding is
vital to ensure safe operation. Do not defeat the purpose of the grounding type plug by
modifying the plug or using an adapter.
9
Prior to installation, use an outlet tester or a voltmeter to check the AC receptacle for the
presence of earth ground. If the receptacle is not properly grounded, the installation must
not continue until a qualified electrician has corrected the problem. Similarly, in the case
of DC input power, check the DC ground (s).
10
If a three-wire grounding type power source is not available, consult a qualified electrician
to determine another method of grounding the equipment.
11
Models with DC power inputs must be connected to an earth ground through the terminal
block Earth/Chassis Ground connectors. This is a safety feature. Equipment grounding is
vital to ensure safe operation.
