Hardware Setup and Non-Managed Use
The 3240S supports the T1 and E1 I/O cards. This chapter describes the switch and jumper settings
and LEDs for the system and the I/O cards. If you choose to use the 3240S as a non-managed system,
it will be ready for operation at the end of the setup and installation.
Before installing the 3240S, unpack it and its accessories; save the shipping carton and packing
material for reuse. Inspect the 3420S and shipping carton; if it is damaged, file a claim with the
freight carrier. Canoga Perkins is not liable for damage in shipment.
Setting Up I/O Cards
The 3240S supports T1 and E1 I/O cards.
Physical Slots and Time Slots
The 3240S divides the front-end bandwidth into four logical time slots; each card, either T1 or E1,
uses two time slots. You can insert a card in either physical slot, but each card can communicate only
with the card that uses the same time slots in another 3240S. Each pair of time slots can be used only
once. In general, set the card in physical slot 1 to time slots 1 and 3; set the card in physical slot 2 to
time slots 2 and 4. To avoid confusion, the management software flags an error if cards with the
same time slots are in different physical slots, although it does not affect system operation.
T1X, 4-Port I/O Card
Each T1X card supports four T1 channels and either Binary 8 Zero Substitution (B8ZS) or Alternate
Mark Inversion (AMI) line coding, uses two time slots, and uses one physical slot in a chassis. The
T1X card includes four connectors, all either female DA-15 or RJ-48C and configured as DCE.
Chapter 5 lists all connector pin assignments.
To set up the T1X card, see Figure 5 and follow these steps:
1. Set the time slot at jumper W32. Set both ends of the same link to the same time slot. Install the
jumper for time slots 1 and 3. Remove the jumper for time slots 2 and 4.
2. Switches SW1 and SW3 control the line length and line coding for the ports:
•
Port 1: Line coding, SW1, 4; line length, SW1, 1-3
•
Port 2: Line coding, SW1, 8; line length, SW1, 5-7
•
Port 3: Line coding, SW3, 4; line length, SW3, 1-3
•
Port 4: Line coding, SW3, 8; line length, SW3, 5-7
