Selecting the Type of Management Access
You will likely use different methods to implement management access to the system during the initial
startup and reload operations and during normal operations, although technically the same methods might
be used. Before gathering the items needed to complete the hardware installation, decide which methods to
use for each type of connection, so that the necessary terminals or PCs, LAN equipment, modems, and
cables are available. Table 3-9 lists the equipment requirements for each type of connection.
The following sections describe the types of management access in detail:
• Access During the Initial Startup and Reload Operations
• Access During Normal Operations
• Management Access Options
Warning Risk of electrical shock. The system uses DC power sources, which can cause severe injury. To
reduce the risk, the DC power sources must be installed only in restricted access areas
(dedicated equipment rooms, equipment closets, or the like) in accordance with Articles
110-17, 110-26, and 110-27 of the National Electric Code, ANSI/NFPA 70. Connect the chassis
to a –48 VDC source that is reliably connected to earth.
Warning Risk of electrical shock. After the power cables are connected to the chassis and the fuse panel,
the system is fully powered on. To reduce the risk, always remove the fuses for both the A- and
B-side power sources in the fuse panel before connecting the power cables to the chassis.
Warning Risk of electrical shock. Improper grounding can result in an electrical shock. To reduce the
risk, this equipment must be connected to a protective ground in accordance with the
instructions provided in this guide.
Warning Risk of electrical shock. There are mechanical and electrical shock hazards present throughout
the system if one or more of the cards is removed. To reduce the risk, only qualified personnel
are allowed to service the system.
Laser Risk of severe damage to your eyes. All versions of the optical SFPs are Class 1 devices, which
use lasers to convert electrical signals to optical signals that can damage your eyes. To reduce the
risk when working with optical SFPs, keep the connectors covered until you are ready to connect
the fiber-optic cables. When you remove a cover, do not stare into or directly view the laser beam
emerging from the connector.
Warning Risk of personal injury. This equipment does not provide safety isolation between any port that
is connected to a digital network termination point and any other port to which terminal
equipment may be connected. To reduce the risk, disconnect the telecommunications network
cables before removing the card to which they are connected.
