This chapter provides instructions for the installation of the optional cable management tray that you can use to route cables in an open-rack, non-redundant configuration:
You will need to obtain the optional cable management tray kit and one each BXM T3/E3 cable bracket kit for each BXM T3/E3 card.
Step 2 Install left and right brackets, using two nuts to secure each bracket, Figure 12-1.
Step 2 Lower the tray into the lower rest position Figure 12-3.
You should raise the tray only when necessary to access the Power Entry Modules (PEMs), typically for replacement or to install a second PEM. Figure 12-4 shows the tray in the raised position.
To raise the tray to provide access to the PEMs:
Step 2 With two hands, pull the tray towards yourself and up.
Step 3 Raise the tray to the upper position and lower it onto the upper slots.
To attach the BXM T3/E3 cable bracket to each BXM T3/E3 card as shown in Figure 12-5:
Step 2 Place the bracket in position as shown.
Step 3 Screw in and tighten the captive screw.
Step 4 Insert one end of the cable tie through the hole in the bracket.
To route the cables as shown in Figure 12-6 and Figure 12-7:
Step 2 Dress the cables upward to provide a service loop.
Step 3 Bundle the cables by using cable ties.
Step 4 Wrap the cable strap around the cables and secure them to the cable management bracket.
Note To disconnect cables from a card, pull on the cable connector locking sleeve as you pull the cable connector away from the card connector. |
To route cables as shown in Figure 12-8:
Step 2 Route cables from the cards through the cable clamps on the cable management tray.
Step 3 Secure the cable management tray to the cable tray brackets by inserting and tightening securing screw, one to each bracket.
Figure 12-9 shows how to raise the cable management tray with cables in place, to provide access to the Power Entry Modules (PEMs).
