This chapter covers the following topics:
This chapter explains how to install a single shelf MAX TNT. If you are installing a multishelf system, read this chapter and Chapter 3, "Performing Basic Configuration," before installing your system.
Table 2-1 lists the sections describing installation tasks you might need to perform, and provides a brief description of each.
Table 2-1. MAX TNT installation overview
Before you install the MAX TNT, make sure you have the following:
- Phillip-head screwdriver to install the MAX TNT slot cards.
- Anti-static wrist straps and mats.
- Suitable location with adequate power.
- At least one active T1 or E1 line set up for bidirectional calling. (Bidirectional calling allows you to test the MAX TNT hardware by having the MAX TNT dial out on one channel and answer on another channel.)
- Local workstation with VT100 terminal-emulation software. (You must assign an IP address through a connection to the serial port of the MAX TNT. Later, you can use Telnet to configure the system.)
- Workstation on a different subnet, from which you can ping the MAX TNT to verify the configuration.
- IP address for the MAX TNT.
- Default gateway for the MAX TNT, if your set up requires one.
The MAX TNT allows you to freely mix and match the various types of expansion cards with few restrictions. Here is information to help determine power requirements:
- You can install a maximum of six digital modem cards in a single MAX TNT shelf.
- The most power consumed by any of the MAX TNT cards is 40 watts, dual-height or single-height. Therefore you can plan for 640 watts for a fully-loaded MAX TNT shelf.
- For AC power, provide power via two dedicated 120 VAC/20 A outlets with a dedicated ground.
The MAX TNT package contents vary, depending on the base unit and slot cards you order. The first step after opening the package is to verify that you have the system you ordered. Figure 2-1 shows a standalone MAX TNT shelf. A multishelf system combines multiple interleaved shelves in a chassis.

Figure 2-1. Standalone shelf front panel
Verify that the package also contains the following items:
- Power cable.
- Personal Computer Memory Card International Association (PCMCIA) cards.
- Rack mounting kit for mounting the MAX TNT in a 19- or 23-inch rack.
- Any slot cards you ordered with the system. If you ordered them separately, check the separate packaging.
If you are missing any items, contact your MAX TNT distributor.
Figure 2-2 shows the back panel of a standalone shelf. The shelf controller is always slot 17. The remaining slots are numbered 1 through 16. (For information about a installing a slot card in a slot, see the chapter about the card, later in this manual.)

Figure 2-2. Back panel of the MAX TNT
Before you begin installing the hardware, you need some understanding of the ports and other items on the MAX TNT shelf controller. Refer to Figure 2-3 and Table 2-2 for the location and function of each element on the shelf controller.

Figure 2-3. MAX TNT shelf-controller backpanel
Table 2-2. Description of shelf-controller backpanel items
The lights (also called LEDs) on the MAX TNT back panel can be helpful if you experience a problem, especially if it occurs shortly after power on. Figure 2-4 shows the location of the lights on the back panel, and Table 2-3 describes them.

Make sure the switch is not set to 0. Figure 2-5 shows an acceptable setting. (In a multishelf system, each shelf must have a unique setting.)
Caution: If the rotary switch is set to 0, the MAX TNT will not operate correctly.

Figure 2-5. Verifying the rotary switch setting
Also, make sure the PCMCIA card is inserted in the first PCMCIA slot.
Caution: Do not remove the PCMCIA flash card while the MAX TNT is running. Doing so
can damage the card and require its replacement.
Before installing the MAX TNT in a rack, you must install the MAX TNT rack ears as illustrated in Figure 2-6. These rack ears should come with your unit. If you do not receive them, contact your Ascend reseller. Apply 7 to 8 in/lbs of torque to each screw.

Figure 2-6. Installing the MAX TNT rack ears
You can mount the MAX TNT in either a 19- or 23-inch rack. A single MAX TNT shelf has the dimensions shown in Figure 2-7.

Figure 2-7. MAX TNT dimensions
Insert the unit in the rack and secure it as shown in Figure 2-8. If you need more information, refer to the instructions that came with your rack.
You need not concern yourself with air gaps between MAX TNT shelves on a rack, because the MAX TNT fans sufficiently cool each shelf.

Figure 2-8. Mounting the MAX TNT in a rack
If your MAX TNT package includes slot cards that are not already installed in your MAX TNT, insert the cards now. Proceed as follows:
- Hold the slot card with the panel facing you and the lock screw on the left, and insert the
card into the open slot as shown in Figure 2-9.

Figure 2-9. Inserting a slot card into a MAX TNT
- Push the card along the internal card guides until jackscrew on the right side of the card
panel is seated in the hole in the MAX TNT backpanel. The panel of the slot card should
touch the back panel of the MAX TNT.
Caution: Do not force the slot card into the slot. Doing so can damage the card or slot
connector.
Tighten the lock screw on the left side of the card, as shown in Figure 2-10.
All MAX TNT slot cards are hot-swappable, meaning that you can safely insert or remove cards while the MAX TNT power is on.

Figure 2-10. Tightening slot card lock screws
All MAX TNT systems have an Ethernet port on the shelf-controller. This Ethernet port is designed for out-of-band management and light traffic loads. It is not intended to be the primary Ethernet interface for the system. If your MAX TNT will be routing heavy Ethernet traffic use an Ethernet card.
If do not need a LAN interface, skip this section and proceed to Connecting a workstation to the serial port.
To connect the MAX TNT to your LAN, plug Ethernet LAN cables into one of the unit's Ethernet ports. Figure 2-11 shows the Ethernet LAN cable connected to the shelf controller Ethernet interface for out-of-band management.

Figure 2-11. Connecting Ethernet cable
To perform the initial configuration of the MAX TNT, you must connect a cable to MAX TNT serial port.
- Connect a serial cable from your workstation to the MAX TNT as shown in Figure 2-12.

Figure 2-12. Connecting a serial cable to MAX TNT
- Set the terminal emulation package in your communications software as follows:
- 9600 bps
- Direct connection
- 8 data bits
- No parity
- 1 stop bit
- No flow control
To power on the MAX TNT:
- Position yourself so that you can watch the lights on the back panel while you view the
monitor display.
- Turn on the power to the unit. After a few minutes, the terminal emulator should display
the following messages (if it does not, press Ctrl-L to refresh the screen):
*** TNT, unconfigured unit***
