After you install the RackNest 2/14 in your 19" rack (refer to the RackNest’s manual), take these steps to install a line driver card in the RackNest:
1.Insert the card into an empty slot on the RackNest (see Figure 4-3). Do not use excessive force. If the card does not go in easily, remove the card, realign it with the RackNest’s enclosure guides, and push it into place.
NOTE
When the RackNest 2/14 is ON, personnel are not exposed to any voltage over 30V on any card or accessible area of the nest. Still, take all reasonable precautions to avoid electric shock.
2.Tighten the nut on the top of the card.
3.Push the bottom of the card as far into the RackNest as it will comfortably go, to ensure that its card-edge connector makes full contact with the RackNest’s.
4.Run an appropriate cable from your DTE to the corresponding DB25 connector (“J1”) on the back of the RackNest:
•ME445C-530(RS-530) units: You can use standard RS-530 (DB25 male- to-male) cable. Refer to Table 4-2 for more information.
•ME445C-35 (V.35) units: Either this cable needs to be specially pinned (see Table 4-3) and have a DB25 male connector at the RackNest end and an M/34 male connector at the DTE end, or you need to use a correctly pinned, short DB25-male-to-M/34-female cable or similar adapter to patch between the V.35 (M/34 male-to-male) cable and the RackNest’s DB25 connector. Call Black Box for a quote on this type of cable.
•ME445C-X21 (X.21) units: Either this cable needs to be pinned for RS-530 to X.21 (see Table 4-5) and have a DB25 male connector
at the RackNest end and a DA15 (“DB15”) male connector at the DTE end, or you need to use a correctly pinned, short DB25-male-to-DA15- female cable or similar adapter to patch between the X.21 (DA15 male-to-male) cable and the RackNest’s DB25 connector. Call Black Box for a quote on this type of cable.
5.If you haven’t already done so, install the remote RackNest 2/14. Repeat steps 1 through 4 at the remote site.
