Cisco 10000 ESR AC Power Entry Module Installation This publication contains instructions for installing the AC Power Entry Module (PEM) in the Cisco 10000 Edge Services Router (ESR). If you are not familiar with the Cisco 10000 router, see the Cisco 10000 ESR System Description, and the Cisco 10000 ESR Hardware Installation Guide for additional information.
Product Description Product Description The AC PEM provides power conversion directly from the facility VAC input power (100 VAC to 240 VAC) to the –48V VDC used internally by the system (see Figure 1). AC power is delivered to the AC PEM from the VAC connection power cable to the power cord attached to the PEM. AC PEM POWER FAULT 30004 Figure 1 There are two PEM bays in the chassis; however, you only need one PEM to power the router. You can install an additional PEM for power redundancy.
Prerequisites and Preparation Prerequisites and Preparation Before you perform any of the procedures in this guide, Cisco recommends that you: • Read the safety guidelines in the next section and review the electrical safety and ESD-prevention guidelines in the Cisco 10000 ESR Hardware Installation Guide. • Ensure that you have all of the necessary tools and equipment before beginning the installation (see the “Installation Guidelines” section on page 4).
Installation Guidelines Warning This warning symbol means danger. You are in a situation that could cause bodily injury. Before you work on any equipment, be aware of the hazards involved with electrical circuitry and be familiar with standard practices for preventing accidents. To see translations of the warnings that appear in this publication, refer to the Regulatory Compliance and Safety Information document that accompanied this device.
Adding or Replacing an AC PEM Adding or Replacing an AC PEM This section describes how to add or replace an AC PEM in the Cisco 10000 chassis. It contains the following procedures: • Removing the Front Cover, page 5 • Installing a Second AC PEM, page 7 • Replacing an AC PEM, page 12 • Troubleshooting the Installation, page 19 Removing the Front Cover Use the following procedure to remove the front cover from the system.
Adding or Replacing an AC PEM Step 2 Remove the cover by lifting it up slightly and then pulling it toward you (Figure 3). Figure 3 Removing the Front Cover FANS OK FAN FAILURE MULTIFAN FAILURE When hot CAUTION removal swapping this fan be done and replaceme tray, system in under two nt must shutdown minut will occures or .
Adding or Replacing an AC PEM Installing a Second AC PEM Use the following procedure to install a second AC PEM in the bottom power bay for redundancy. Step 1 Attach an antistatic wrist strap to your wrist and to an ESD socket on the chassis, or to a bare metal surface on the chassis or frame (Figure 4).
Adding or Replacing an AC PEM Step 2 Loosen the captive screws to remove the blank cover from the bottom power bay (Figure 5). Figure 5 Removing the Blank Cover FANS OK FAN FAILURE MULTIFAN FAILURE When hot CAUTION removal swapping this fan be done and replacem tray, system in under two ent must shutdow minu n will occutes or r.
Adding or Replacing an AC PEM Step 3 Install the new AC PEM all the way into the power bay to ensure a secure connection to the backplane, and then tighten the captive screws (Figure 6). Figure 6 Installing an AC PEM FANS OK FAN FAILURE MULTIFAN FAILURE When hot CAUTION removal swapping this fan be done and replacem tray, system in under two ent must shutdow minu n will occutes or r.
Adding or Replacing an AC PEM Step 4 Connect the power cord from the PEM to your power cord that connects to the facility VAC input. Step 5 Set the AC power cord connectors in a cord strain relief (canoe) to prevent them from accidently disconnecting (Figure 7).

Adding or Replacing an AC PEM Replacing an AC PEM Use the following procedure to replace an AC PEM. Note Step 1 The illustrations in this guide show how to replace the AC PEM from the bottom power bay. The procedure is the same to replace an AC PEM in the top power bay. Attach an antistatic wrist strap to your wrist and to an ESD socket on the chassis, or to a bare metal surface on the chassis or frame (Figure 9).
Adding or Replacing an AC PEM Step 2 Caution Power off the PEM you are replacing (Figure 10). Do not power off both AC PEMs in a redundant system or the system shuts down and all data traffic stops. Only power off the AC PEM you are replacing.

Adding or Replacing an AC PEM Step 4 Loosen the captive screws on the PEM and remove the PEM from the chassis using the handle on the faceplate (Figure 12). Figure 12 Removing an AC PEM FANS OK FAN FAILURE MULTIFAN FAILURE When hot CAUTION removal swapping this fan be done and replacem tray, system in under two ent must shutdow minu n will occutes or r.
Adding or Replacing an AC PEM Step 5 Install the new PEM all the way into the power bay to ensure a good connection to the backplane, and tighten the captive screws on the PEM (Figure 13). Figure 13 Installing an AC PEM FANS OK FAN FAILURE MULTIFAN FAILURE When hot CAUTION removal swapping this fan be done and replacem tray, system in under two ent must shutdow minu n will occutes or r.
Adding or Replacing an AC PEM Step 6 Connect the power cord from the PEM to the power cord that connects to the facility VAC input. Step 7 Set the AC power cord connectors in a cord strain relief (canoe) to prevent them from accidently disconnecting (Figure 14).
