Installing the NHP160 Line Interface Card
BROADway supports up to two NHP160 sixteen port T1/E1 line interface cards installed in slots UIP-
1 and UIP-2. If you plan to support NHP160 redundant operation, you must install an NHP160 card in
slot UIP-2, even if there is no NHP160 card installed in slot UIP-1 (the last four ports on the NHP160
in UIP-2 are designated the protection ports for both slots).
Cabling and Inserting the NHP160 Line Interface Card
Before inserting the NHP160 line cards into the BROADway system, you must seat the NHP160 cable
into its SCSI connector on the card. The NHP160 cards are cabled directly from a port on the line card
itself. The electrical cables are dressed to the left hand side of the chassis.
To cable and insert the NHP160 cards:
1. Attach the NHP160 cables to each NHP160 card.
2. Insert the NHP160 card into the chassis. Open the ejector tabs and slide the card into its proper
slot until you feel resistance, then push to close the ejector tabs into their locking position
against the metal rails. Check that the card is firmly in place by applying pressure to the ejector
tabs to seat the card fully into the chassis.
WARNING! W HEN INSTALLING OR REPLACING BROAD WAY HARDWARE , ALWAYS ADHERE
TO GOOD PRACTICE WITH RESPECT TO ESD PROCEDURES — USE A REGULARLY AND PROPERLY
TESTED GROUNDING STRAP .
3. Dress the cables through the cut-outs in the metal chassis on the left hand side of the system.
Ensure that you leave enough slack in the NHP160 cable to enable the fan tray to be removed
without interference.
