Hardware Installation Manual 34 Document #: LTRT-10764
Mediant 500 MSBR
To earth the device:
1. Connect an electrically earthed strap of 16 AWG wire (minimum) to the chassis'
earthing screw (located on the rear panel), using the supplied washer.
2. Connect the other end of the strap to a protective earthing. This should be in
accordance with the regulations enforced in the country of installation.

5.2 Connecting to WAN
This section provides a description on how to cable the WAN port. The cabling procedure
depends on the ordered WAN interface:
Copper Gigabit Ethernet (GbE) – see Section 5.2.1 on page 34
Fiber-optic GbE – see Section 5.2.2 on page 35
ADSL/2+ and VDSL2 – see Section 5.2.3 on page 37
3G Cellular WAN modem – see Section 5.2.4 on page 39
Note: The device supports multiple WAN redundancies, where multiple WAN interfaces
can serve as backups for the primary or a backup WAN interface. For example, if the
main WAN interface is Copper GbE and it fails, the device switches over to the SHDSL
WAN interface. If this WAN interface also fails, the device switches over to the 3G WAN
interface, and so on. For configuring WAN redundancy, refer to the MSBR Series CLI
