3a. Determine which fuse pairs are to supply power to the Total Access 838.
3b. Remove the fuses from the Aand Bslots for the pair.
3c. Connect RET A, PWR A, RET B, and PWR B to the power connector. PWR refers to respective –48 VDC
or ±24 VDC power sources; RET refers to respective returns.
4. Apply power and check voltages.
WARNING: Installing fuses in the fuse and alarm panel at this stage will provide power to the Total Access
838. There will be power to pins and connectors on the rear panel and inside the Total Access 838.
Exercise caution to avoid electrical shock.
4a. Install appropriate fuses in the slots in the fuse and alarm panel that serves the Total Access 838.
4b. Using a voltmeter, verify that the operating voltage is within the specifications for A or B power feeds. For
more information, refer to Specifications on the back.
5. Connect the CRIT (critical), MAJOR, and MINOR alarm leads from the alarm panel to the Common (C),
Normally Open (NO), and Normally Closed (NC) wire-wrap terminals on the Total Access 838 rear panel as
required.
CONNECT AND LOGIN TO SYSTEM
Connect to the front panel RS-232, DB-9 connector labeled CONSOLE to log on and provision the Total Access
838 by way of VT100 terminal or VT100 terminal emulation software such as HyperTerminal or ProComm Plus.
Craft port defaults are as follows:
♦Data Rate: Auto
♦Asynchronous Data Format: 8-data bits, no parity, 1-stop bit, and no flow control
Press ENTER to activate the CLI.
NOTE: The default username and password are “ADMIN” and “PASSWORD” in all capital letters.

DESCRIPTION
The Total Access 838 SHDSL Ethernet in the First Mile (EFM) is a Metro-Ethernet Forum (MEF) compliant, EFM
bonded NTU designed for cost-effective deployment of voice and data services to small and medium size
businesses supporting up to eight two-wire SHDSL loops. The Total Access 838 accepts SHDSL or eSHDSL and
delivers 10/100Base-T Ethernet for customer LAN extension. The Total Access 838 terminates the SHDSL loops in
an RJ-21 connector and supports data rates from 192 kbps to 5.7 Mbps per copper pair. The Total Access 838
provides an aggregate data rate up to 45.6 Mbps over a single EFM bonding group.

♦MEF Compliant
♦One integrated EIA-232 configuration port (DCE)
♦Four integrated 10/100Base-T Ethernet ports
♦One SFP to support Gigabit Ethernet
♦Eight two-wire eSHDSL loops
♦WAN Protocol: IEEE 802.3ah EFM bonding
♦Command Line Interface (CLI)
♦Front panel LEDs
♦Wall mounting hardware included
♦Remote Management - EOC/CLI using Virtual Terminal, Telnet by way of Management VLAN
INSTALLATION AND TURN-UP
After unpacking the unit, inspect it for damage. If damage is noted, file a claim with the carrier and then contact
ADTRAN. For more information, refer to the warranty.
Follow the steps listed below to wallmount or rackmount the Total Access 838.
1. Attach mounting brackets to the side of the Total Access 838 in the correct orientation for either rackmount or
wallmount using the two screws provided for each bracket.
♦To rackmount the unit, use the appropriate rack-type screws to mount the Total Access 838 into the rack.
WARNING: Do not upset the stability of the equipment rack after installation is complete.
♦To wallmount the unit, secure the Total Access 838 to the wall with appropriate screws.
2. Connect the frame ground from the frame ground lug on the upper right rear panel of the Total Access 838 to
the equipment rack grounding screw or other appropriate grounding connection.
3. Make power connections to the Total Access 838.
NOTE: A readily accessible disconnect device, such as a rackmount fuse and alarm panel that is suitably
approved and rated should be incorporated into the fixed wiring.
Connect to a reliably grounded –48 VDC or ±24 VDC source that is electrically isolated from the AC
source.
The branch circuit overcurrent protection should be a slow-blow fuse or circuit breaker.
