Preparing your site

This section tabulates the following information:

The following table lists the dimensions of the filer.

Note
The next generation of filers and NetCache appliances is 10.5 inches (266.7 mm) high and requires 6U of rack space above or below the unit.

The filer weighs approximately 66 lbs (29.94 kg).

The following table lists the maximum environmental conditions that your site must meet to properly run or store your filer.

Environmental condition	Operating condition	Storage condition
Temperature range	50º F to 104º F (10º C to 40º C)	-4º F to 149º F (-20º C to 65º C)
Relative humidity (noncondensing)	10% to 90%	10% to 90% in original shipping container; otherwise, 50%.

The following table describes the recommended minimum clearance for the filer.

Recommended minimum clearance	U.S.	Metric
Front clearance	9 in.	22.9 cm

Rear clearance	30 in.	76.2 cm

Clearance in vertical rack space above filer for rear vents	0.5 in.	3.81 cm

You can order your filer for AC or DC power.

The following table lists the electrical requirements for AC power.

Condition	Requirement
AC power supply	100 to 240V AC single phase
Maximum rated current per AC input	5A at 100 to 240V AC
Typical current per AC input	2A at 100V AC (F810, F820, F825, and F840) 2.25A at 100V AC (F880)
Inrush current	25A maximum at 110V AC per power supply 30A maximum at 220V AC per power supply
Frequency	50 to 60 Hz

The following table lists the electrical requirements for DC power.

Condition	Requirement
DC power supply	-40 to -60V DC
Maximum rated current per DC input	5A at -40V
Typical current per DC input	4A at -48V DC (F810, F820, F825, and F840) 4.5A at -48V DC (F880)
Inrush current	15A/100 msec for 48Vin per power supply (for reference, 25A/100 msec for 78V)

The following table lists the power requirements for both AC and DC filers.

Power	Rating
Watts	300 maximum (with Power Factor correction)
BTU/hr	1025 maximum

The freestanding equipment rack must have

A width of 19 inches (48.26 cm)
Front installation rails compliant with EIA standard RS-310-C
Adequate space for air circulation directly above the filer ventilation holes
If you install a device above the filer, leave at least 0.5 inches (1.3 cm) of space directly above the ventilation holes. You can install equipment directly on the unvented area as long as it does not extend over and block the ventilation holes on the filer.
