1RU. These dimensions do not include the rack-mount brackets.
You can mount the router in a standard (ETSI) 19-inch (48.3 cm) equipment rack or 600mm ETSI rack
or a 23-inch ETSI rack.
The Cisco ASR 901 10G router includes the following hardware features:
•Eight T1/E1 RJ45 ports.

Power Supply
Figure 1-3 Cisco ASR 901 10G Router—Rear View
Note The grounding architecture of this product is DC-isolated (DC-I) for DC-powered products.
DC-powered products have a nominal operating DC voltage of 48 VDC. Minimal steady state DC
operating voltage is 19.2 VDC.
LEDs
The Cisco ASR 901 10G chassis and interface modules contain LEDs to assist in troubleshooting. For
more detailed description of the LEDs, see the “Reading the LEDs, page A-4.
Power Supply
The Cisco ASR 901 10G router is equipped with an internal -24/-60 Volts Direct Current (VDC). The
router is provided with a single AC power supply or DC (1+1 Redundant) power supply. The power input
connectors are located at the front left-side side of the router. The DC power connector has the standard
A and B feeds for DC redundancy. The DC power supply is compatible with the range of DC input
voltages specifically available at cell sites.
See Table 1-1 for the DC power supply specifications and Table 1-2 for the AC power supply
specifications.
Safety Precautions
Observe the following general safety precautions and recommendations in planning the source power
requirements for the Cisco ASR 901 10G router (for additional safety information, see the “Safety
Guidelines” section on page 2-1:
•Check the power at your site before router installation (and periodically after installation) to ensure
clean power (free of spikes and noise) is being received.
•Always disconnect the power source and unplug the power cable before working on the router.

Chapter 1 Introduction
Power Supply
•Install proper grounding for the site to avoid damage from lightning and power surges.
Warning To avoid electric shock, do not connect safety extra-low voltage (SELV) circuits to telephone-network
voltage (TNV) circuits. LAN ports contain SELV circuits, and WAN ports contain TNV circuits. Some
LAN and WAN ports both use RJ-45 connectors. Use caution when connecting cables. Statement 1021
Warning There is the danger of explosion if the battery is replaced incorrectly. Replace the battery only with
the same or equivalent type recommended by the manufacturer. Dispose of used batteries according
to the manufacturer’s instructions. Statement 1015
Warning This unit might have more than one power supply connection. All connections must be removed to
de-energize the unit. Statement 1028
Warning The intrabuilding ports of the equipment or subassembly MUST NOT be metallically connected to
interfaces that connect to the OSP or its wiring. These interfaces are designed for use only as
intrabuilding interfaces (Type 2 or Type 4 ports as described in GR-1089-CORE), and require isolation
from the exposed OSP cabling. The addition of primary protectors is not sufficient protection in order
to connect these interfaces metallically to OSP wiring.
Warning To comply with the Telcordia GR-1089 NEBS standard for electromagnetic compatibility and safety,
connect the (Management Ethernet) ports only to intra-building or unexposed wiring or cable. The
intrabuilding cable must be shielded and the shield must be grounded at both ends. The intra-building
port(s) of the equipment or subassembly must not be metallically connected to interfaces that connect
to the OSP or its wiring. These interfaces are designed for use as intra-building interfaces only (Type
2 or Type 4 ports as described in GR-1089-CORE) and require isolation from the exposed OSP cabling.
The addition of Primary Protectors is not sufficient protection in order to connect these interfaces
metallically to OSP wiring.

Power Supply
Warning This product requires surge protection as part of the building installation. To comply with the
Telcordia GR-1089 NEBS standard for electromagnetic compatibility and safety, an external surge
protective device (SPD) is required at the AC power service equipment.
The Cisco ASR 901 10G router uses two 3-pin connectors (part number 27-1892-01) for DC input to the
power supply. The terminal block is part of the accessory kit (part number 53-3438-01), which ships with
the Cisco ASR 901 10G router.
The Cisco ASR 901 10G router uses a single 3-pin connector (29-1609-01) for AC input to the power
supply.
The ground wire connects to a 2-hole lug, which connects to the corresponding mounting point. With the
connector installed in the chassis, the pins numbered from left to right are 1, 3, and 2, respectively.
Figure 1-4 shows the pinout configurations for the connector, based on the power source.
Note You can use connector A or B or both.

Environmental Monitoring Temperature Sensor
Figure 1-4 Power Supply Connector Pinouts
Environmental Monitoring Temperature Sensor
The Cisco ASR 901 10G router has a temperature sensor to detect overtemperature conditions inside the
chassis. The overtemperature detection trips at 70°C. This condition is reported to the processor as an
interrupt, where the software generates the appropriate alarms. If the router reaches a temperature of
90°C, the power supply cycles itself to prevent the router from exceeding the maximum temperature
while being powered up.
Note Auxiliary port is not supported.

Router Interface Numbering
Cisco ASR 901 10G Router
Each network interface on a Cisco ASR 901 10G 10G router is identified by a slot number and a port
number, explained in this sequence:
•Logical slot numbers starts from 0 for all built-in interfaces. The numbering format is Interface
type Slot number/Interface number.Interface (port) numbers begin at logical 0 for each interface
type.
•Logical interface numbering for 10G SFP+ ports runs from 0/0 through 0/1. Ports are numbered
bottom to top.
•Logical interface numbering for T1/E1 ports on the TDM interface module runs from 0/0 through
0/7. Ports are numbered bottom to top, left to right.
•Logical interface numbering for the built-in ethernet ports runs from g0/0 through g0/3, the combo
