EtherSHELF
The EtherSHELF, an optional 12 unit, 4U shelf is available for large-scale installations.
To mount an EtherNID in the EtherSHELF, L-shaped brackets must be attached to the left and
right side of the unit.
Grounding the EtherSHELF
Connect the EtherSHELF to a ground point on the rack as follows:
1. Turn OFF power to the shelf. However, to channel ESD voltages to ground, do not unplug
the power cable. Remove all network interface cables.
Warning: Before proceeding to the next step, ensure that power is removed from the DC
circuit. To ensure that all power is OFF, locate the circuit breaker on the panel board that
services the DC circuit, switch the circuit breaker to the OFF position, and then tape the
switch handle of the circuit breaker in the OFF position.
2. Strip one end of a 10-AWG wire to expose approximately 0.75 in. (20 mm).
3. Crimp the two-hole grounding lug around the exposed wire.
Attach brackets before mounting in the drawer.
