T1 Modem Bank Power Supply Installation/Replacement
The T1 Modem Bank operates with either a single power supply installed or with two power supplies installed. Dual
power supplies allow a T1 Modem Bank to share load balancing so that one power supply can take over if the other
power supply becomes inoperable. To install a power supply (or supplies) into a new T1 Modem Bank unit, or to
replace or add a power supply in an existing T1 Modem Bank unit, follow the directions in this section. See “Power
Supply Removal” on page 73 if you need instructions for removing a power supply from a T1 Modem Bank.
