4Installing a Brocade NetIron XMR 32000 routerUsing the insertion or extraction toolDue to the high density of cables that the Brocade NetIron XMR 32000 router can support, it maybe difficult to insert and remove the RJ45 and optical connectors. An insertion or extraction toolhas been provided in the Brocade NetIron XMR 32000 accessory kit to make this task easier. Referto Figure 194.FIGURE 194Insertion or extraction Tool211 Hooked tab 2 Stepped tabUse the tool to grasp the boot or the plug of the modular connector at the narrow end (the endclosest to the attached cable), and insert the connector into the proper interface module. Graspingthe boot or plug at the wide end during insertion may cause the tool to be difficult to release andremove.When using the tool to extract the boot or plug of a modular connector, cover the entire length ofthe boot or plug with the tool. Notice that one end of the tool has a “hook” side. Use this side tocompress the locking tab while you remove the connector.Brocade NetIron XMR 32000 cable managementBrocade NetIron XMR 32000 cable management is designed to ensure access to the powersupplies at the bottom of the router, and to keep the air inlet clear in the center of the router (this isessential for proper cooling). Cable management hardware at the top, bottom and sides of therouter help you route the cables in the proper direction.In general, cables from the outer interface modules are routed horizontally and away from therouter. Cables from the remaining modules in the upper half of the router are routed up, thenoutwards along the channels.The modules in the lower half of the router are routed downwards, above the power supplies.Figure 195 shows the cable routing, with the upper and lower cable management covers removedfor clarity.Cable management notesThe following rules apply when setting up cable management for a heavily- or fully-loaded system:• All cables must be firmly connected, supported, and contained.• Use cable cinches, spaced approximately every 24 inches, to secure all of the cables for eachmodule into a single bundle. This is especially important at the ends nearest the moduleconnections. Each cable cinch holds up to 8 MRJ21 cables, or 48 RJ45 cables.280 Brocade MLX Series and NetIron XMR Hardware Installation Guide53-1002373-02
