ADTRAN MX2820 Quick Start Manual

MX2820
23 INCH
CHASSIS
CLEI: M3M1W00B_ _
DESCRIPTION
The MX2820 chassis houses multiple M13 multiplexers that consolidate T1/E1 signals
into T3 circuits. The MX2820 (P/N 1186001L2) houses nine redundant M13 multiplexers.
The MX2820 chassis also houses a single SCU that provides management capabilities to
the MX2820 system.
Features of the MX2820 include:
I
1:1 redundancy
I
Hot-swappable MUX cards
I
Embedded SNMP and Telnet management
I
Simplified configuration through the VT100 terminal menu structure
I
Meets the requirements for NEBS Level 3 compliance
TURN-UP STEPS
1. Attach mounting ears.
2. If necessary at this point, attach cable tie bar.
3. Mount chassis in rack.
Warning: Care should be taken not to upset the stability of the equipment rack.
4. Remove appropriate fuses from fuse panel.
5. Remove metal cover from the right side of the back panel.
Note: Silkscreen on cover references the following connections:
6. Wire wrap CHAIN posts and MIN alarm relay posts and route wire downward.
7. If STS-1, wire wrap CLKB and CLKA posts and route wire downward.
8. Wire wrap ACO posts and route wire downward.
9. Wire wrap AUX3, AUX2, and AUX1 alarm input posts and route wire downward.
10. Wire wrap MAJ and CRIT alarm posts and route wire downward.
11. Connect frame ground on barrier strip.
Caution: Per GR-1089-CORE October 2002, Section 9, MX2820 system is designed and
intended only for installation in a DC-C (common) bonding and grounding
system. The chassis ground wire must be of equal or greater ampacity than the
wire connected to the VDC return.
The MX2820 system is not intended or designed for installation in a DC-I
(isolated) bonding and grounding system.
Note: A readily accessible disconnect device, such as a rackmount fuse and alarm panel

that is suitably approved and rated should be incorporated in the fixed wiring.
SUBJECT TO ELECTROSTATIC DAMAGE
OR DECREASE IN RELIABILITY.
HANDLING PRECAUTIONS REQUIRED.

Note: Connect to a reliably grounded VDC source, which is electrically isolated
from the AC source.
12. Connect RET B, PWR B, RET A, and PWR A on barrier strip.
Note: PWR = Respective –48 VDC or ±24 VDC source, RET = respective return
13. Insert appropriate fuses into fuse panel.
14. Using a voltmeter, verify that the operating voltage is within specifications
for A & B power.
15. Remove appropriate fuses from panel and replace the metal cover that was
removed in step 5.
16. Insert appropriate fuses into panel, and if not done in step 2, attach cable
tie bar.
17. Connect 10/100BaseT Ethernet and NTWK MGMT X.25 interfaces.
18. Route DSX-3 coax and tie to upper tie bar.
19. Route DSX-1 IN cables below upper tie bar and tie to upper tie bar.
20. Route DSX-1 OUT cables beneath lower tie bar and tie to lower tie bar.
