Mounti ng the PDX218
In addition to having room to make cable connections, the PDX218 requires six inches (15.25 cm) of clearance behind the rear pa nel for connectors and cable bends. Adequate air flow must also be assured around the chassis to provide sufficient cooling. (Operating ambient temperature will affect the amount of air circ ulation required to keep the PDX218 within its temperature limitations.)
1. Pull the slide-out section to the full y extende d position. See Figure 2-5.
WARNING: To prevent injury, two people are required to lif t the PDX218. The
!
PDX218 is too heavy for one person to install in the rack. WARNING: To prevent seriou s injury , in sure that the rack i s anc hored to the f loo r
!
so that it cannot tip over when the PDX218 is extended out of the rack.
2. Insert the ends of the chassis sections into the slide-out sections.
3. Push the chassis toward the rack until the chas sis sections lock int o the intermediate sections.
4. Press the stop latches in the intermediate sections and push the chassis toward the rack until the latches sna p into their holes.

Power Conne ctions

Power Sou r ce
The PDX218 operates from a single-phase power source having one of its current-carryi ng conductors a t or near earth ground (the neutra l conductor). A fuse on the line conductor provides over-current protection. Grass Valley Group does not recommend connection to systems whose power source has both current carrying conductors live with res pect to ground, such as phase-to-phase in multi-phase systems.
Source Power Frequency and Voltage Ranges
The PDX218 operates at line frequencies of 50 or 60 Hz at nominal voltages from 100 to 240 VAC. Table 2-1 lists the power cord shipped with the PDX 218. Figure 2-10 shows the location of the power cord connec tor and the power switch.

Creating a File System on the PDX218
Now that the PDX218 is connected to the Profile system, you must use the Profile Disk Utility to conf igure the disk driv es to stor e media by cre ating a file syste m (also called making a data set in t he Profi le Disk Util ity). Refe r to the Profile Family User Manual, “Using the Profile Disk Utility”, for detailed inf ormation about creating a file system on the PDX218 disk drives. In addition, c onsider the following when crea ting file systems with the Profile Disk Utility:
• When one PDX218 chassis is connected to a Profile system, the disk drives can be grouped in the following ways:
- You can create a you a single file system including all externa l disk drives and
internal disk drives ( if installed).
- You can create a single ex tern al file syst em whi ch includes all eigh t extern a l
disk drives and a single interna l file system which includes all inte rnal drives (if installed).
• When two PDX 218 chassis are connected to a Profile system, the disk drives can be grouped the following ways:
- You can create a single file s ystem including al l exter na l di sk dri ve s and al l
internal disk drives ( if installed).
- You can create a single external file system which includes all sixteen external
disk drives. If internal disk drives are installe d, you c an create a single internal file system.
- You can create two external file syste ms, eight disk driv es each. Each eight disk
file system include s four disks from both PDX218 chassis. If internal disk dr ives are installed, you can also cre ate a single internal file system.
• If you are connecting the PDX218 to a Profile system with internal disk drives smaller than 18GB, you may want to create two file systems. When creating a file system, the Profile system limits the usable disk space of the larger drives to the size of the sma llest drives in the file s ystem. For exampl e, if you are connecting the PDX218 to a PDR100 with 4 GB disks, configure the PDX218 as a separate file system. Making one file system including the internal 4GB drives and the external 18GB drives, limits the PDX218 storage capacity because the Profile system recognizes the drive s in the PDX218 chassis as only 4GB drives.
• Some thir d party control software does not recognize internal and external file systems. In this case, you must create one file system which includes all internal and external disk drives.
• Oper ating the PDX218 with the Profile Video File Server requires Profile system software 2.2.X greater than 2.2.4, 2.4.X greater than 2.4.4, or 2.5.X and greater.

Maintenance

There is no specifically require d periodic maintenance for the PDX218. Cleaning the exterior is on an “as needed” basis. Checking and cleaning or replacing the air filter will depend on the operating envir onment. Procedures for doing these tasks are discussed below.
WARNING: To avoid damage to the unit, if a liquid of any kind is spilled onto the
!
PDX218, immediately turn power Off and insure that both the inside and the outside are completely dry before re-applying power.

Cleaning

Clean the PDX218 often enough to prevent dust or dirt from acc umulating. Dirt acts as a thermal insulating bla nket that prevents effective heat dissipation, and can provide high-resi stance electrical l eakage paths between conduc tors or components in a humid environment.
Exterior
Clean the dust from the outside by wipi ng with a sof t cloth or small brush . A brush is especially usefu l to remove dust from around the connectors. Hardened dirt may be removed with a cl oth dampened i n wa ter or a 50 % isopropyl al cohol sol ution . Do not use an abrasive cl ea ne r.
Interior
!
Clean the inter ior by lo osening a ccumulate d dust with a dry, soft br ush. Onc e the dir t is loosened, remove it with low-pre ssure air (high-velocity air can damage some parts). Remove hardene d dirt or grease wit h a cotton-tipped applica tor dampened with a solution of mild detergent and water. Do not use an abrasive cleaner. If the circuit board assembly must be removed for cleaning, follow the removal/replacement instructions.
After cleaning, a llow the int erio r to thor oughly dry bef ore appl ying power to the unit .
CAUTION: Do not allow w ater to get inside any enclosed assembly or component. Do not clean any plastic material s with organic cleanin g solvents, such as benze ne, toluene, xylene, aceton e, or similar compounds, because they may damage the plastic.
