The Cisco 10000 Edge Services Router (ESR) is a high capacity Layer 3 router optimized to support selected IOS software services at wire speed performance on thousands of DS1/T1 connections. Designed primarily for use in a telco central office environment, it provides interfaces that connect to large numbers of subscribers using low-speed circuits, and then funnels all of that subscriber traffic into a small number of high-speed trunk interfaces. The chassis has eight line card slots and two slots for Performance Routing Engine (PRE) modules.
The Cisco 10000 is designed to meet and exceed the most stringent ISP requirements for product availability and reliability. Its features include:
In addition to PRE Redundancy, SONET/SDH line cards can be configured for 1+1 APS to accommodate failure of either a line card or the transmission facility carrying trunk traffic to upstream equipment.
The Cisco 10000 ESR is designed to scale to unprecedented levels with plans to further increase scalability in future releases. Initial release provides support for up to:
For CT3 line cards, this equates to:
For channelized OC-12 line cards, this equates to:
The Cisco 10000 and power subsystem support the following key features:
The flash memory present on Cisco 10000 line cards is used to store a simple ROM monitor/boot loader. The loader executes following a system reset, line card reset, or line card insertion.
Line card images may also be stored in PRE flash memory or on an external TFTP server.
The PRE stores the system configuration in a 512KB NVRAM device. Configuration information read from NVRAM is buffered in RAM following initialization, and is written to the device when you save the configuration.
The Cisco 10000 ESR is Network Equipment Building Standards (NEBS) Level 3 compliant. This includes:
Less than 22 inches in height (you can configure up to three Cisco 10000 ESRs per 7-foot rack).
The chassis supports redundant AC or DC power, and contains:
At product introduction, the Cisco 10000 supports the following processor and interface cards:
All of the high performance processing engines in the PRE are based on advanced application specific integrated circuits (ASICs). These ASICs direct traffic to and from the router line cards.
Figure 1-1 shows the front panel of the PRE.
The front panel on the PRE contains three ports with RJ-45 connectors (see Figure 1-1):
Two PCMCIA Type II card slots can store the Cisco IOS image or a system configuration file on a flash memory card. The system can also boot from the software stored on the flash memory card. See "Removing the PCMCIA Flash Card" section for more information about inserting and removing flash cards from the PRE.
LEDs on the front panel of the PRE provide a visual indication showing the status of PRE operation (see Figure 1-1). The LEDs are separated into three categories:
Alarm relay contacts on the Cisco 10000 let you connect the router to a site alarm maintenance system. This allows critical, major, and minor alarms generated by the Cisco 10000 to be displayed on both the PRE front panel and to external visual or audible alarms connected to the system. See the "Connecting Alarm Indicators" section for more information about alarm connections.
Pressing the alarm cutoff (ACO) switch on the (primary) PRE during an alarm condition shuts off the external alarm, but does not deactivate the alarm LEDs on the PRE front panel. Alarm LEDs on the front panel are deactivated only after the condition that caused the alarm is corrected.
Table 1-1 describes the LEDs and switch on the PRE.

The Cisco 10000 ESR Channelized T3 line card supports 6 channelized DS3 ports per card.
Each DS3 port can be independently configured all the way from a clear channel T3 down to and including DS1 and DS0 connections on the same port, with a maximum of 128 channels per DS3 port.
Each channelized T3 line card can support any combination of DS3/DS1/DS0s up to 768 channels.
The Cisco 10000 can support up to 7 channelized T3 line cards, with a maximum capacity of 42 T3 connections or 1176 T1 connections per chassis. A fully loaded 7-foot rack can supports up to 126 T3 connections, or 3528 T1 connections.
Figure 1-2 shows the front panel for the channelized T3 line card.

The port uses a Gigabit Interface Converter (GBIC) that supports Gigabit Ethernet rates on a variety of gigabit Ethernet interface types (SX, LX/LH, ZX) which can be changed or upgraded at any time (see Table 1-6). The Cisco 10000 supports multiple GE line cards to support connectivity to multiple destinations and for network layer redundancy.
Figure 1-4 shows the front panel for the Gigabit Ethernet line card.

Warning Because invisible radiation may be emitted from the aperture of the port when no fiber cable is connected, avoid exposure to radiation and do not stare into open apertures. |
The following tables list the proper single mode or multimode optical fiber cables to use to connect your router to a network:
The Cisco 10000 chassis is designed for mounting in 19-inch or (optional) 23-inch equipment racks, and contains the following components:
Figure 1-8 shows a fully loaded chassis with redundant PREs, power entry modules (PEMs), and line cards.
The Cisco 10000 ESR uses a blower module (Figure 1-9) containing four fans to supply cooling air to the chassis.
The blower module is located at the top of the chassis and connects to a connector on the chassis.
1. Four internal fans draw cooling air into the front of the chassis and directs it across the internal components to maintain an acceptable operating temperature.
2. The air is exhausted through openings in the rear of the chassis.
Although the blower module supports hot-swapping and can be replaced without interruption to system operation, do not power down the system without the blower unit for more than a few minutes to prevent overheating.
The DC PEM provides filtering and supplies DC power to the chassis electronics (Figure 1-10). DC PEMs receive input power (-48 VDC from building centralized power source) through terminal block connections located on the rear of the chassis.
Table 1-9 describes the LEDs on the DC PEM.
| LED | Description |
|---|---|
Power (green) | PEM is powered on and is operational. |
Fault (yellow) | The PEM is not operating correctly (see the Cisco 10000 ESR Troubleshooting Guide). |
Miswire (yellow) | -48V and RTN (+) wires are reversed (see the "Troubleshooting Installation Problems" section). |
The AC PEM provides power conversion directly from the facility VAC input power (100-240 VAC) to the -48V VDC used internally by the system (Figure 1-11). AC power is delivered to the AC PEM from the VAC connection power cable to the power cord attached to the PEM.
Table 1-10 describes the LEDs on the AC PEM.
| LED | Description |
|---|---|
Power (green) | PEM is powered on and is operational. |
Fault (yellow) | The PEM is not operating correctly (see the Cisco 10000 ESR Troubleshooting Guide). |
