Foundry Networks M2404F, M2404C manual Grounding the Switch

Foundry NetIron M2404C/M2404F Metro Access Switches

For each DC power block a set of a minimum 2x18AWG cables shall be used with suitable end terminal legs matching the conductor’s gauge. Use a RED lead to for the positive conductor and a BLACK lead for the negative conductor. It is recommended that only UL listed components be used for the DC power connections.

CAUTION	For a DC system, use a grounding wire of at least 10 American Wire
	Gauge (AWG). The 10 AWG wire should be attached to an agency-
	approved crimp connector, crimped with the proper tool. The crimp
	connector should allow for securement to both ground screws on the
	enclosure.
CAUTION	For the DC input circuit to the system, make sure there is a Listed 10 amp
	circuit, minimum -48Vdc, double pole, on the input to the terminal block.
	The input wiring for connection to the product should be Listed copper
	wire, 18 AWG, marked VW-1, and rated minimum 90 deg. C.

NOTE	There is no connection needed for GND. Only the ground wire is connected to
	the Grounding Stud.

Grounding the Switch

WARNING Before connecting power to the switch, make sure that both grounding posts in the rear panel are firmly connected to a reliable ground through a #10 AWG grounding wire terminated by a UL-listed two-hole long-barrel 5/8 10 AWG compression lug with hole size and spacing as shown in Figure

15below.

The Burndy YAZV10-2TC14or an equivalent UL-listed two-hole compression lug is recommended.

To connect the switch to the ground, proceed as follows:

1.Prepare a minimum #10 AWG grounding wire terminated by a crimped two-hole lug with hole diameter and spacing as shown in Figure 15. Use a suitable crimping tool to fasten the lug securely to the wire. Adhere to your company’s policy as to the wire gauge and the number of crimps on the lug.
