Task 002: Installing the 19” Fan Tray
The 19" fan tray is necessary for a chassis housing one or more 10306
or 10224 CO modem cards. The fan tray is installed under each
BS1900 shelf and contains six forced-air cooling fans to ensure
sufficient cooling for operation. Use this procedure only to connect fan
trays for use with the 10306 or 10224 CO modem cards. The following
instructions are for installation of the -48 V DC and 110/220 V AC
(switch selectable) fan trays.
Step
Procedure
1.)
Seat the fan tray at the bottom of the rack, leave room for at least
1 RU (Rack Unit) of air entry, then mount the two (2) side brackets
(19” mounting ears) to secure the tray in the shelf. (For 23” racks,
use 23” adapter ears.) Brackets are adjustable for flush and mid-
mounting. Refer to Figure 2-2, "Fan Tray Mounting," on page 39.

WARNING: POSSIBLE EQUIPMENT DAMAGE! AC Fan
Trays are shipped with an air filter frame. To
ensure proper airflow, the frame must be
installed. DO NOT install an air filter for the
AC Fan Tray, only the frame.
