This chapter describes how to remove and install a new or replacement power supply. Your switch ships with at least one power-supply
module (AC or DC, depending on your order).
The power-supply modules are field-replaceable units (FRUs) and are hot-swappable when deployed in nonhazardous locations.
For translations of the safety warnings in this chapter, see the Regulatory Compliance and Safety Information for the Cisco IE9300 Rugged Series Switches on Cisco.com.
Power Supply Modules
This section contains information about the power supply modules compatible with the switch.
All the power supply modules in the following table are compliant for hazardous environments.
Table 1. Power Supply Modules
Model
Description
PWR-RGD-LOW-DC-H
Low voltage DC.
PWR-RGD-AC-DC-H
AC and high-voltage DC.
PWR-RGD-AC-DC-250
AC and high-voltage DC.
PWR-RGD-AC-DC-400
AC and high-voltage DC.
Note
For detailed specifications of the products in the preceding table, see the Cisco Catalyst IE9300 Rugged Series Switch data sheet.
The 250- and 400-watt power supplies provide a higher PoE power budget on IE9310 and IE9320 systems that support PoE. These
higher capacity supplies are also compatible with optical and non-PoE copper systems, although the higher capacity is not
necessary for operation.
Note
The power supplies in the preceding table are recommended for new installations. The older PWR-RGD-LOW-DC and PWR-RGD-AC-DC
power supplies (without the -H suffix) are supported for users who already own them. However, these older supplies are not
approved for use in hazardous locations and must not be used in HazLoc applications.
The following illustration shows a PWR-RGD-AC-DC-H power supply. The PWR-RGD-LOW-DC-H power supply appears identical; the
only visual difference is the label. The PWR-RGD-AC-DC-250 power supply is similar to the other power supplies. However, it
extends 30 mm (1.18 inches) from the rear of the switch. The PWR-RGD-AC-DC-400 switch also is similar to other power supplies, but extends 39.88 mm (1.57 inches) from the rear of
the switch.
