MAINTENANCE

The Total Access 1248 does not require routine hardware

maintenance for normal operation. Do not attempt repairs in

the field. Repair services may be obtained by returning the

defective unit to ADTRAN. Refer to the warranty for further

information. Field support for software is provided through

upgrade facilities.

Fan Modules

Four fans are installed in the Total Access 1248 in a removable

module to maintain the hardware within proper operating

temperature tolerances. With the exception of the filter, the fan

module is not field serviceable. The fan module (P/N

1179675G1) is field replaceable and is available from

ADTRAN.

To remove a fan module, perform the following steps:

1. Loosen the screw that holds the fan module in place.

2. Remove the fan module by pulling it straight out of the

chassis.

To install a new fan module, perform the following steps:

1. Insert the new fan module by pushing it straight into

the chassis.

2. Tighten the screw that holds the fan module in place.

Fan Filters

The Total Access 1248 fan module comes with a single fan

filter. The filter is designed to remove particles from the air

before it is pushed through the system.

Replacement filters are available from ADTRAN individually

(P/N 1179676G1) and in quantities of 20 (P/N 1179676G2).

The filter should be inspected at least every 90 days and

replaced as necessary.

To replace a filter, remove the fan module, remove the old filter

material and tuck the new filter in, ensuring that the edges of

the filter are behind the metal tabs provided to hold the filter.

COMPLIANCE

The Total Access 1248 is NRTL listed to the applicable UL

standards. The Total Access 1248 meets or exceeds all appli-

cable requirements of NEBS, Telcordia GR-63-CORE, issue 3,

and GR-1089-CORE, issue 4. The Total Access 1248 is

intended for deployment in EEC’s, in Pedestals, directly in the

OSP, and in locations where the NEC applies. Install the Total

Access 1248 in a restricted access location.

This device complies with Part 15 of the FCC rules. Operation

is subject to the following two conditions:

1. This device may not cause harmful interference.

2. This device must accept any interference received,

including interference that may cause undesired

operation.

Changes or modifications not expressly approved by ADTRAN

could void the user’s authority to operate this equipment.

♦ Electrostatic Discharge (ESD) can damage electronic

modules. When handling modules, wear an antistatic

discharge wrist strap to prevent damage to electronic

components. Place modules in antistatic packing

material when transporting or storing. When working on

modules, always place them on an approved antistatic

mat that is electrically grounded.

♦ Per GR-1089-CORE, Section 9, the Total Access 1248 is

designed to be deployed in DC-C (common) configuration

or DC-I (isolated) installation.

♦ Per GR-1089-CORE the Total Access 1248 is designed

and intended for installation as part of a Common

Bonding Network (CBN). The Total Access 1248 is not

designed nor intended for installation as part of an

Isolated Bonding Network (IBN).

♦ The Total Access 1248 frame ground terminal must be

connected to a reliable earth ground.

♦ Connect to a reliably grounded –48 VDC source which is

electrically isolated from the AC source. The branch

circuit overcurrent protection shall be a fuse or circuit

breaker rated minimum –48 VDC, Maximum 3A.

NOTE

♦ The POTS and ADSL+POTS ports are classified as Type 1, 3,

and 5 as defined in Appendix B of GR-1089-CORE, Issue

4 and meet the lightning and power fault criteria with

any primary protector that meets any of the voltage

limits of GR-974-CORE or GR-1361-CORE (i.e., carbon

blocks, gas tubes, solid states, etc.). Solid-state primary

protectors are not recommended as they could affect the

signal integrity of the ADSL.

♦ Current limiting protectors are not required.
