SUBJECT TO ELECTROSTATIC DAMAGE
OR DECREASE IN RELIABILITY.
HANDLING PRECAUTIONS REQUIRED.
Electrical cable compliance
Table 1 shows the Compliance Codes for HFAC. The
HFAC complies with the requirements covered under
UL 1950 third edition and is intended to be installed
in an enclosure with an Installation Code (IC) of “B”
or “E.”
NOTE
This product is intended for installation in
Restricted Access Locations Only. Input
current at maximum load is 1A at -48 VDC.
Maximum output at overcurrent condition is
165 mA at -190 VDC.
Configuration
Operation of the HFAC is influenced by three sets of
configuration option switches (see Figures 2 and 3).
Shelf Address
Two rotary switches (U38 and U39) are provided to
program the shelf’s address. In a system where
several shelves are under the common control of one
ADTRAN E220 HCOT-CTL System Controller, each
individual shelf must be programmed with a unique
shelf address. Addresses range from 00 to 99. In a
system that does not utilize the HCOT-CTL System
Controller, the shelf address is not used. To program
The HFAC supports the HTU-Cs / H2TU-Cs listed
below.
• 1242024L1 • 1242002L7
• 1242002L2 • 1242029L1
• 1242002L5 • 1242029L2
• 1242002L6 • 1244001L1
• 1245001L2 • 1246001L2
• 1245001L9 • 1221001L2
• 1245011L1
The differences in functionality when working with
list-specific HTU-Cs / H2TU-Cs or HREs / H2Rs, if
any, are called out in this practice. Also, the HFAC
has necessary interface software for communications
with the HCOT-CTL (ADTRAN p/n: 1240009L1,
1244051L1, 1221051L1). See appropriate HCOT
practices for installation and maintenance information.
The HFAC collects and presents performance
information for each circuit deployed in the shelf. It
also allows control of all provisioning information for
each circuit. The unit can also be configured to
provide advanced alarm processing features.
2. INSTALLATION
After unpacking the unit, inspect it for damage. If
damage is discovered, file a claim with the carrier,
then contact ADTRAN. See Warranty and Customer
Service.
