The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

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.
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.
|
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.

Observe the guidelines in this section when removing or installing a power-supply module.
A power-supply module that is only partially connected to the switch disrupts the system operation.
 Warning |
Blank faceplates and cover panels serve three important functions: they prevent exposure to hazardous voltages and currents inside the chassis; they contain electromagnetic interference (EMI) that might disrupt other equipment; and they direct the flow of cooling air through the chassis. Do not operate the system unless all cards, faceplates, front covers, and rear covers are in place. Statement 1029 Avertissement : Les plastrons et les panneaux de protection remplissent trois fonctions importantes : ils protègent l’utilisateur des tensions et des flux électriques dangereux présents à l’intérieur du châssis; ils aident à limiter les interférences électromagnétiques (EMI) qui pourraient perturber d’autres appareils; enfin, ils dirigent la circulation d’air de refroidissement dans le châssis. Utilisez le système uniquement si les cartes, les plastrons, ainsi que les caches avant et arrière sont en place. Énoncé 1029 |
Warning |
Do not reach into a vacant slot while installing or removing a module. Exposed circuitry is an energy hazard. Statement 206 Avertissement : Évitez de toucher à un logement vide lors de l’installation ou du retrait d’un module. Les circuits exposés représentent un risque de décharge électrique. Énoncé 206 |
Warning |
Only trained and qualified personnel should be allowed to install, replace, or service this equipment. Statement 1030 Avertissement : Toute installation, tout remplacement ou toute réparation de cet équipement doit être effectué par un personnel qualifié et compétent. Énoncé 1030 |
Warning |
Avoid using or servicing any equipment that has outdoor connections during an electrical storm. There may be a risk of electric shock from lightning. Statement 1088 Avertissement : es équipements pourvus de connexions extérieures ne doivent pas être utilisés ni entretenus pendant un orage. La foudre est susceptible de provoquer des décharges électriques. Énoncé 1088 |
Follow the guidelines and procedures in this section to install a power-supply module in the PSU1 or PSU2 slot.
Warning |
The covers are an integral part of the safety design of the product. Do not operate the unit without the covers installed. Statement 1077 Avertissement : Les couvercles font partie intégrante de la sécurité du produit. N’utilisez pas l’unité si les couvercles ne sont pas installés. Énoncé 1077 |
Warning |
This unit might have more than one power supply connection. All connections must be removed to de-energize the unit. Statement 1028 Avertissement : Il se peut que cet appareil ait plus d’une connexion de bloc d’alimentation. Pour mettre l’appareil hors tension, vous devez débrancher toutes les connexions. Énoncé 1028 |
 Caution |
Equipment installation must comply with local and national electrical codes. Attention : l’installation de l’appareil doit respecter les codes électriques nationaux et locaux. |
