Before you begin

• 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.

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.

Checking the package contents

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.

Understanding the back panel

Understanding the shelf-controller backpanel

Figure 2-3. MAX TNT shelf-controller backpanel

Table 2-2. Description of shelf-controller backpanel items

Backpanel item	Description
Uplink/Downlink	Ports for intershelf communications.
UTP port	Ethernet port to connect Unshielded Twisted-Pair (UTP) Ethernet LAN cable to the MAX TNT.
Serial port	Ethernet port to connect Shielded Twisted-Pair (STP) Ethernet LAN cable to the MAX TNT.
PCMCIA slots	Two flash PCMCIA slots, labeled 1 and 2.
DRAM upgrade slot	PCMCIA slot for DRAM upgrades.
Shelf-Select rotary switch	This switch is used for MAX TNT multishelf configurations. Each shelf in a multishelf system must have its rotary switch set to a unique number. (See Chapter 4, "Installing a Multishelf System," for information about configuring a multishelf system.)

The lights on the shelf-controller back panel

Figure 2-4. Location of the MAX TNT lights

Table 2-3. MAX TNT lights

Lights	Description
1	Green. On when the unit has power.
2	Green. On for any functioning shelf in a multishelf system, whether it is configured as master or slave.
3	Yellow. Behaves as follows: On after you reset the unit Off after the unit passes Power-On Self Test (POST) and is running Blinks if a fatal error has occurred
4	Yellow. This is the multishelf alarm light. If the master shelf goes down (if, for example, the multishelf cable is removed), this light goes on, on each slave shelf, after about nine seconds. Note that on the master shelf, this alarm light does not go on.
5	Green. On when Power Supply A is installed and working.
6	Green. On when Power Supply B is installed and working.
7	Yellow. On when Power Supply A is installed and a fault occurs.
8	Yellow. On when Power Supply B is installed and a fault occurs.
9	Green. On when an Ethernet 10Base-T link has been established.
10	Green. On when an Ethernet AUI link has been established.
11	Green. On when the Ethernet link is active.
12	Green. On when the Ethernet link is active and link integrity has been confirmed.
13	Green. On when there is Ethernet activity between MAX TNT shelves.
14	Yellow. On when an Ethernet collision occurs.

Verifying the rotary switch setting and PCMCIA card

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.

Rack mounting the MAX TNT

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

Installing a slot card

1. 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

1. 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

Connecting the MAX TNT to the LAN

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

Connecting a workstation to the serial port

To perform the initial configuration of the MAX TNT, you must connect a cable to MAX TNT serial port.

1. 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

1. 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

Powering on the MAX TNT

To power on the MAX TNT:

1. Position yourself so that you can watch the lights on the back panel while you view the monitor display.

2. 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***
   The system date is: Thu Aug 11 12:34:39 1997
   If incorrect, please enter the proper value using this command:
   date yymmddhhmm
   Please configure these profiles:
   SYSTEM
   IP-GLOBAL
   IP-INTERFACE
   LOG
   SERIAL
   for your operating environment.
   TNT>
   

3. Check the PCMCIA flash-card file system to verify that there are no errors on the card or in its contents:

   ffs check in progress for card 1...
   Dir 1 not in use
