WARNING
If an ADTRAN T200 HTU-C (p/n 1245006L6)
is used in the HR4 Shelf, the network
connections are made on the modular jacks,
and the customer connections are made on
the 50-pin CHAMP connector (see Figure 8).
Incorrect connections could result in injury
from high voltage present at the Network
interface.
3. INSTALLATION
The HR4 has four available slots for plug-in cards.
HTU-R units can occupy any available slot. Other
locally powered T400 plug-ins can be deployed in the
HR4. This requires use of an external -48 V supply.
4. MAINTENANCE
The ADTRAN HR4 requires no routine maintenance
to operate properly. Tests and maintenance for the
individual plug-ins should be connected in accordance
with the recommendations and procedures prescribed
by the manufacturer of specific plug-in.
ADTRAN recommends that repairs on the shelf not be
performed in the field. Repair services may be
obtained by returning damaged units to ADTRAN
(see Warranty and Customer Service).
5. SPECIFICATIONS
Specifications for the HR4 are listed in Table 1.
