Chapter 3 Installing and Removing AC- and DC-Power-Supply Modules

Power-Supply Module Installation

Each DC-power input (A ± and B ±) is connected to both power-supply module 1 (PSU 1) and power-supply module 2 (PSU 2). The power-supply modules cannot be powered independently. DC inputs and returns are diode-isolated (Figure 3-9).

Preparing for Installation

Obtain these necessary tools and equipment:

•Ratcheting torque screwdriver with a number-2 and a number-1 Phillips head that exerts up to 15 inch-pounds (in-lb).

•Panduit crimping tool with optional controlled-cycle mechanism (model CT-720, CT-920, CT-920CH, CT-930, or CT-940CH).

•Wire-stripping tools.

•Copper ground wire (insulated or noninsulated) for the ground connection.

•Dual-hole, right-angle ground lug from the switch accessory kit (for the Cisco ME 3400E-24TS-M and the Cisco ME 3400EG-12CS-M).

•Dual-hole ground lug from the switch accessory kit (for the Cisco ME 3400EG-2CS-A).

•Four leads of 16-gauge copper wire.

•Four-position DC-terminal-block connector from the accessory kit.

•Amphenol PCD: ELFF0422S1 (Cisco part number 29-6063-0). http://www.amphenolpcd.com/

Grounding the Switch

To make sure that the equipment is reliably connected to earth ground, follow the grounding procedure instructions and observe these warnings:

Warning This equipment must be grounded. Never defeat the ground conductor or operate the equipment in the absence of a suitably installed ground conductor. Contact the appropriate electrical inspection authority or an electrician if you are uncertain that suitable grounding is available. Statement 1024

Warning When installing or replacing the unit, the ground connection must always be made first and disconnected last. Statement 1046
