Routine maintenance
Routine maintenance in the Media Platform consists primarily of cleaning the air
filters on a scheduled basis, and removing accumulated dust and dirt from the
equipment on an as-needed basis. In addition to the cleaning, the Emergency Repair
Disk should be updated routinely as part of any hardware or software installation.
Cleaning or replacing air filters
In order to operate in all environmental conditions, the Profile XP and PAC216
require clean, unrestricted internal air flow. For both units, internal fans pull air into
the chassis through filters in the front panel. The air then flows across the boards and
power supply and exhausts from the chassis through the rear panel and right side panel
in the case of the PAC216.
The Profile XP uses one large filter and two small filters, and the PAC216 uses a
single filter. Check these air filters frequently for dust and grime buildup. Much of the
buildup of dust and lint can be removed through the front panel with a portable
vacuum cleaner. However, frequent cleaning ensures adequate, clean cooling air to
the equipment.
Cleaning the filters
The air filters supplied with this Profile XP and PAC216 can easily be cleaned and
used again. Wash them in warm water and mild detergent. Make sure the filters are
dry before reinstalling them and powering up the Profile XP or PAC216.
Additional air filters
Additional air filters can be ordered directly from Grass Valley. See the Replaceable
Parts Lists in Chapter 11 for the part numbers.
Removing and replacing the Profile XP filters
Removal of the air filters for cleaning or replacement requires removal of the front
panel, but does not require shutting down the Profile XP. To remove the Profile XP
air filters:
1. Grasp the front panel at both sides and snap loose from the chassis as shown on
page 84.
2. Remove the large filter from the mounting posts on the inside of the panel cover;
detach the small filters from the two access doors. The small filters are each held
in place by six hook and loop fasteners.
3. Install the cleaned or replacement filters.
4. Position the front panel cover at the chassis so that the cover alignment posts
engage the holes in the chassis; snap the front panel cover onto the chassis.
